===== Load env file =========

load_dotenv() HUGGINGFACE_TOKEN = os.getenv(“HUGGINGFACE_TOKEN”)

if not HUGGINGFACE_TOKEN: raise ValueError(“HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.”)

===== Load YAML Config =====

with open(“config_article.yml”, “r”, encoding=“utf-8”) as file: config = yaml.safe_load(file)

api_info = config[“API”] workflow_steps = config[“workflow”] persona_steps = config[“persona_workflow”] prompts = config[“prompts”] rag_queries = config[“rag”] parameters = config[“parameters”]

✅ Dictionary to Store Dynamically Generated Inputs

generated_inputs = {}

Dictionary to store RAG results with metadata

rag_results = {}

===== Initialize Hugging Face LLM =====

model_url = api_info[“model_url”] api_token = HUGGINGFACE_TOKEN llm = HuggingFaceAPI(api_url=model_url, api_token=api_token)

===== INITIALIZE RAG ==================

===== Initialize RAG Retriever ====

Load embedding model

embedding_model = SentenceTransformer(‘all-MiniLM-L6-v2’)

===== Define paths =========

scientific_path = config[‘rag’][‘scientific’][‘json’] scientific_faiss = config[‘rag’][‘scientific’][‘faiss’] scientific_meta = config[‘rag’][‘scientific’][‘embeddings’]

diary_path = config[‘rag’][‘diary’][‘json’] diary_faiss = config[‘rag’][‘diary’][‘faiss’] diary_meta = config[‘rag’][‘diary’][‘embeddings’]

# Load indices when needed

diary_folder = os.path.join(master_folder, “sample_texts”)

# Load texts from folders

scientific_texts = load_texts_from_folder(scientific_folder)

diary_texts = load_texts_from_folder(diary_folder)

Init retriever class

#rag_retriever = RagRetrieve(embedding_model, llm, scientific_texts, diary_texts, scientific_index, diary_index) rag_retriever = RagRetrieveWithMeta(embedding_model, scientific_faiss, scientific_meta, diary_faiss, diary_meta)

as you can see this is aiming to execute a chain. The chain is meant to make it write an article with a specific structure. What i want to do now is to offer the option to have a chain or a chat version. so when the user starts the gradio app they should pick one o[tion and then the corresponding ui should unfold. how will i do this?

ChatGPT

To provide an option for users to choose between Chain Execution and Chat Mode, you’ll need to:

1. Add a Selection Dropdown or Radio Buttons at Startup to let users pick a mode.
2. Dynamically Show the Corresponding UI based on their selection.

---

Steps to Implement This:

1. Add a Dropdown or Radio Button at the Beginning
   • The user picks between “Structured Article Generation” (Chain Execution) and “Conversational Mode” (Chat Mode).
2. Use Conditional UI Rendering
   • Use gr.update(visible=True/False) to dynamically show the selected UI.

---

Updated Gradio Implementation:

Modify your gr.Blocks() layout to include a selection at the start.

import gradio as gr

# Function to show the appropriate UI based on user selection
def show_selected_mode(mode):
    if mode == "Structured Article Generation":
        return gr.update(visible=True), gr.update(visible=False)
    elif mode == "Conversational Mode":
        return gr.update(visible=False), gr.update(visible=True)
    return gr.update(visible=False), gr.update(visible=False)

# ✅ Start Gradio UI

    gr.Markdown("# 🌲 **AI Writing Assistant**")

    # 1️⃣ Selection Dropdown to Choose Mode

        label="Choose Mode",
        interactive=True
    )
    confirm_button = gr.Button("Confirm Selection")

    # 2️⃣ Chain Execution UI (Initially Hidden)

    # Functionality: Show UI based on selection
    confirm_button.click(show_selected_mode, inputs=[mode_selection], outputs=[chain_ui, chat_ui])

    # ✅ Launch Gradio
    demo.launch()

---

How This Works

1. The app starts with only the selection UI.
2. The user picks a mode and clicks “Confirm Selection”.
3. Based on the mode:
   • Chain Execution UI is shown for structured article writing.
   • Chat UI is shown for freeform conversation.
4. The rest of the app proceeds as before.

---

Next Steps

• Add specific logic inside the Chat UI to allow interactive conversations.
• Ensure that both workflows (chain execution and chat) are handled properly.
• Customize UI elements further based on the needs of each mode.

You

so i need to have ALL of the gradio ui elements on one script?

ChatGPT

Yes, all Gradio UI elements must be defined in a single script to properly manage visibility and interactivity. However, you can modularize the code by defining functions for each UI section and controlling their visibility dynamically.

How to Structure the Code

1. Define UI Sections Inside gr.Blocks():

   • Have all UI elements inside a single gr.Blocks() scope.
   • Use gr.update(visible=True/False) to dynamically toggle visibility.

2. Use Conditional Rendering:

   • A radio button or dropdown at the start lets users choose between Chain Execution and Chat Mode.
   • A button click event updates the UI to show the relevant section.

---

Example of a Clean and Modular Structure

import gradio as gr

# Function to show either Chain UI or Chat UI
def show_selected_mode(mode):
    if mode == "Structured Article Generation":
        return gr.update(visible=True), gr.update(visible=False)
    elif mode == "Conversational Mode":
        return gr.update(visible=False), gr.update(visible=True)
    return gr.update(visible=False), gr.update(visible=False)

# ✅ Start Gradio UI
with gr.Blocks() as demo:
    gr.Markdown("# 🌲 **AI Writing Assistant**")

    # 🔹 MODE SELECTION: User picks between Chain or Chat mode
    mode_selection = gr.Radio(
        ["Structured Article Generation", "Conversational Mode"],
        label="Choose Mode",
        interactive=True
    )
    confirm_button = gr.Button("Confirm Selection")

    # 🔹 CHAIN EXECUTION UI (Initially Hidden)
    with gr.Column(visible=False) as chain_ui:
        gr.Markdown("## 📄 **Structured Article Generation**")
        start_button = gr.Button("Generate Persona")
        persona_display = gr.Textbox(label="Persona", interactive=False, lines=10, max_lines=10)
        start_conversation_btn = gr.Button("Start Generation Process", visible=False)

        with gr.Column(visible=False) as refinement_elements:
            gr.Markdown("### ✏️ **Refine Persona**")
            refinement_prompt_box = gr.Textbox(label="Edit Persona Refinement", interactive=True,
                                               lines=10, max_lines=10)
            refine_button = gr.Button("Refine Persona")

        with gr.Column(visible=False) as chat_interface:
            chatbox = gr.Chatbot(label="Tree's Perspective Chat")
            prompt_box = gr.Textbox(label="Modify Prompt Before Sending", interactive=True, lines=6)
            next_step_btn = gr.Button("Next Step")
            download_btn = gr.Button("📥 Download History", variant="secondary")
            file_output = gr.File(label="Download your history here")

    # 🔹 CHAT UI (Initially Hidden)
    with gr.Column(visible=False) as chat_ui:
        gr.Markdown("## 💬 **Conversational Mode**")
        chatbox = gr.Chatbot(label="Chat Mode")
        user_input = gr.Textbox(label="Enter message", interactive=True, lines=2)
        send_button = gr.Button("Send")

    # 🔹 Functionality: Show UI based on selection
    confirm_button.click(show_selected_mode, inputs=[mode_selection], outputs=[chain_ui, chat_ui])

    # ✅ Launch Gradio
    demo.launch()

---

How This Works

1. Only the mode selection UI is visible at first.
2. The user picks either:
   • “Structured Article Generation” → Shows the Chain Execution UI.
   • “Conversational Mode” → Shows the Chat UI.
3. Clicking the “Confirm Selection” button updates the UI dynamically.
4. The rest of the interactions proceed as normal.

---

Why This Approach is Best

✅ Everything in One Script → Gradio requires all UI components to be in a single script for interactivity.
✅ Modular & Maintainable → Different sections are contained in separate with gr.Column(...) blocks.
✅ Efficient Conditional UI → gr.update(visible=True/False) dynamically controls visibility.
✅ Scalable → You can easily add more modes or extend functionality.

---

Would you like any additional refinements or improvements? 🚀

You

ok, can you make it with two buttons instead of dropdown?

ChatGPT

Sure! Instead of using a dropdown or radio button, you can use two separate buttons to let the user choose between Structured Article Generation and Conversational Mode.

---

How It Works

1. The user sees only two buttons at first (Choose between “Structured Article Generation” and “Conversational Mode”).
2. Clicking a button reveals the corresponding UI (while hiding the other).
3. Once a mode is selected, the buttons disappear.

Updated Gradio Implementation

import gradio as gr

# Function to handle mode selection
def show_chain_ui():
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

def show_chat_ui():
    return gr.update(visible=False), gr.update(visible=True), gr.update(visible=False)

# ✅ Start Gradio UI

    # 🔹 CHAIN EXECUTION UI (Initially Hidden)
    with gr.Column(visible=False) as chain_ui:
        gr.Markdown("## 📄 **Structured Article Generation**")
        start_button = gr.Button("Generate Persona")
        persona_display = gr.Textbox(label="Persona", interactive=False, lines=10, max_lines=10)
        start_conversation_btn = gr.Button("Start Generation Process", visible=False)

            prompt_box = gr.Textbox(label="Modify Prompt Before Sending", interactive=True, lines=6)
            next_step_btn = gr.Button("Next Step")
            download_btn = gr.Button("📥 Download History", variant="secondary")
            file_output = gr.File(label="Download your history here")

    chat_button.click(show_chat_ui, outputs=[chain_ui, chat_ui, mode_selection])

    # ✅ Launch Gradio
    demo.launch()

---

How This Works

1. At first, the user only sees two buttons:
   • 📝 Structured Article Generation
   • 💬 Conversational Mode
2. When the user clicks one button, it:
   • Shows the corresponding UI
   • Hides the selection buttons (so they can’t switch modes mid-session)
3. The selected mode functions as usual.

---

Why This is Better Than a Dropdown

✅ More User-Friendly → Buttons provide clear options.
✅ Faster Selection → One click instead of opening a dropdown.
✅ Cleaner UI → No unnecessary selections remain visible.

Where Does center-container Go?

✅ It wraps the entire selection screen, meaning both the title and buttons are inside it.
✅ This ensures everything is centered both vertically and horizontally.

How Your UI Will Look Now

✅ Title is centered
✅ Buttons are stacked vertically
✅ Everything is centered in the middle of the page

Your CSS already has the right styles. This should now look perfect! 🚀 Let me know if you need any fine-tuning. 😊

You

it didn’t work. the buttons and title are still at the top pf the page

ChatGPT

If the buttons and title are still at the top of the page, we need to ensure that the Gradio root container (gr.Blocks()) and the center-container class are properly applied to the entire viewport.

---

Fix: Apply Full-Screen Centering

Steps to Fix

1. Make sure Gradio’s root container takes full height.
2. Ensure .center-container fills the viewport (100vh).
3. Set justify-content: center; to properly center elements vertically.

---

Updated style.css

Modify your CSS file to ensure full centering:

/* Centers the title */
.title {
    text-align: center;
    font-size: 24px;
    font-weight: bold;
    margin-bottom: 20px;
}

/* Center the entire container vertically and horizontally */
.center-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;  /* Centers vertically */
    height: 100vh;  /* Takes full screen height */
    width: 100%;  /* Ensure it spans full width */
}

/* Centers buttons and stacks them vertically */
.button-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    gap: 10px;
}

/* Ensure buttons have consistent width and spacing */
button {
    width: 300px;
    font-size: 18px;
}

---

Updated Gradio Script

Make sure the .center-container is applied properly in the gr.Blocks() structure.

import gradio as gr

# Function to handle mode selection
def show_chain_ui():
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

Why This Fix Works

✅ Ensures center-container takes full screen (100vh)
✅ Uses justify-content: center; to center vertically
✅ Wraps all UI elements properly inside gr.Row() for alignment
✅ Maintains button stacking and alignment

This will now properly center your title and buttons in the middle of the page. Let me know if you need further adjustments! 🚀😊

yet it’s still at the top of the page

ChatGPT

It looks like Gradio’s default styling is overriding the vertical centering. The issue is that gr.Row() does not take the full height of the screen by default, which prevents justify-content: center; from properly centering the elements.

---

Fix: Ensure Full-Height Centering

To fix this, update both your CSS and Gradio script as follows.

---

1️⃣ Updated style.css (Fix Full-Screen Centering)

/* Ensure the entire page is centered vertically & horizontally */
html, body {
    height: 100%;
    margin: 0;
    display: flex;
    align-items: center;
    justify-content: center;
    background-color: #121212; /* Dark mode (optional) */
}

/* Centers the title */
.title {
    text-align: center;
    font-size: 24px;
    font-weight: bold;
    margin-bottom: 20px;
}

/* Full-screen container that centers everything */
.center-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;  /* Centers vertically */
    height: 100vh;  /* Takes full screen height */
    width: 100vw;  /* Ensures it spans full width */
}

/* Ensures buttons are stacked properly */
.button-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    gap: 10px;
}

/* Button styling */
button {
    width: 300px;
    font-size: 18px;
}

✅ This CSS ensures your Gradio elements take up the full screen height.
✅ It prevents Gradio’s default layout from restricting the height.
✅ Also improves dark mode appearance (optional).

---

2️⃣ Updated Gradio Script

Now, modify your Gradio script to ensure that center-container applies correctly:

import gradio as gr

# Function to handle mode selection
def show_chain_ui():
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

def show_chat_ui():
    return gr.update(visible=False), gr.update(visible=True), gr.update(visible=False)

def custom_css():
    return gr.HTML('<style>' + open("style.css").read() + '</style>')

# ✅ Start Gradio UI
with gr.Blocks(css="style.css") as demo:
    # Load Custom CSS
    custom_css()

    # Wrap everything inside center-container to ensure full-height centering
    with gr.Column(elem_id="center-container"):
        # Centered Title
        gr.Markdown("<div class='title'>🌲 AI Writing Assistant</div>", elem_id="title")

        # Button container for selection
        with gr.Column(elem_id="button-container"):
            chain_button = gr.Button("📝 Structured Article Generation")
            chat_button = gr.Button("💬 Conversational Mode")

    # 🔹 CHAIN EXECUTION UI (Initially Hidden)
    with gr.Column(visible=False) as chain_ui:
        gr.Markdown("## 📄 **Structured Article Generation**")
        start_button = gr.Button("Generate Persona")
        persona_display = gr.Textbox(label="Persona", interactive=False, lines=10, max_lines=10)

    # 🔹 CHAT UI (Initially Hidden)
    with gr.Column(visible=False) as chat_ui:
        gr.Markdown("## 💬 **Conversational Mode**")
        chatbox = gr.Chatbot(label="Chat Mode")
        user_input = gr.Textbox(label="Enter message", interactive=True, lines=2)
        send_button = gr.Button("Send")

    # 🔹 Button Click Actions to Show UI
    chain_button.click(show_chain_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])
    chat_button.click(show_chat_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])

    # ✅ Launch Gradio
    demo.launch()

---

What This Fixes

✅ Ensures the entire UI takes up full height (100vh)
✅ Properly centers title and buttons both vertically & horizontally
✅ Prevents Gradio’s default layout from interfering with centering
✅ Fixes the issue of elements being stuck at the top

---

Final Steps

1. Replace your style.css with the updated version above.
2. Run the Gradio script again – this should now perfectly center everything.

This should definitely work now. Let me know if you need any more tweaks! 🚀🔥

You

is there a way i can use spacing instead of trying to override gradio’s layout?

ChatGPT

Yes! Instead of overriding Gradio’s default layout, you can use spacers (gr.Markdown("")) and min_height arguments to create a naturally centered layout without modifying the default behavior.

---

Solution: Use Spacing & Layout Adjustments

Instead of forcing a full-screen height override, you can: ✅ Use empty gr.Markdown("") elements as spacers
✅ Adjust min_height inside gr.Column() to help center content
✅ Ensure consistent vertical spacing without CSS overrides

---

1️⃣ Updated Gradio Script (No CSS Overrides Needed)

import gradio as gr

# Function to handle mode selection
def show_chain_ui():
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

def show_chat_ui():
    return gr.update(visible=False), gr.update(visible=True), gr.update(visible=False)

# ✅ Start Gradio UI
with gr.Blocks() as demo:
    # Add a flexible top spacer for centering effect
    gr.Markdown("", elem_id="top-spacer")

    with gr.Column():
        # Centered Title
        gr.Markdown("<h1 style='text-align:center;'>🌲 AI Writing Assistant</h1>", elem_id="title")

        # Empty space for vertical adjustment
        gr.Markdown("", height=30)

        # Button container for selection
        with gr.Column():
            chain_button = gr.Button("📝 Structured Article Generation", scale=1)
            chat_button = gr.Button("💬 Conversational Mode", scale=1)

        # Add a flexible bottom spacer to push elements to the center
        gr.Markdown("", elem_id="bottom-spacer")

    # 🔹 CHAIN EXECUTION UI (Initially Hidden)
    with gr.Column(visible=False) as chain_ui:
        gr.Markdown("## 📄 **Structured Article Generation**")
        start_button = gr.Button("Generate Persona")
        persona_display = gr.Textbox(label="Persona", interactive=False, lines=10, max_lines=10)

    # 🔹 CHAT UI (Initially Hidden)
    with gr.Column(visible=False) as chat_ui:
        gr.Markdown("## 💬 **Conversational Mode**")
        chatbox = gr.Chatbot(label="Chat Mode")
        user_input = gr.Textbox(label="Enter message", interactive=True, lines=2)
        send_button = gr.Button("Send")

    # 🔹 Button Click Actions to Show UI
    chain_button.click(show_chain_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])
    chat_button.click(show_chat_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])

    # ✅ Launch Gradio
    demo.launch()

---

2️⃣ How This Fix Works

✅ No CSS Overrides → Uses built-in Gradio layout tools.
✅ Uses gr.Markdown("") → Adds flexible spacing without breaking Gradio’s default alignment.
✅ Keeps Buttons Centered → Uses scale=1 for uniform button sizing.
✅ Easier to Maintain → No need for 100vh or force-centering with CSS.

---

Would You Like Any Further Adjustments? 🚀

This version should work across different screen sizes without modifying Gradio’s defaults. Let me know if you need any fine-tuning! 😊

You

and the css for top and bottom spacer?

ChatGPT

You don’t need explicit CSS for the top and bottom spacers, since Gradio’s gr.Markdown("") acts as a natural spacer. However, if you want finer control over spacing, you can add a bit of CSS to adjust the height.

---

Updated style.css

/* Centers the title */
.title {
    text-align: center;
    font-size: 24px;
    font-weight: bold;
    margin-bottom: 20px;
}

/* Top and bottom spacers for vertical centering */
#top-spacer {
    height: 20vh;  /* Adjust this value to control vertical centering */
}

#bottom-spacer {
    height: 20vh;  /* Ensures content stays centered */
}

/* Button container for spacing */
.button-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    gap: 10px;
}

/* Button styling */
button {
    width: 300px;
    font-size: 18px;
}

---

How This Works

✅ #top-spacer and #bottom-spacer → Add vertical spacing without breaking Gradio’s layout.
✅ height: 20vh; → Adjust this value to control how much space is added.
✅ No forced full-screen overrides → Keeps Gradio’s default behavior intact.

---

Gradio Script Update (With CSS Applied)

Modify your Gradio script to use elem_id="top-spacer" and elem_id="bottom-spacer":

import gradio as gr

# Function to handle mode selection
def show_chain_ui():
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

def show_chat_ui():
    return gr.update(visible=False), gr.update(visible=True), gr.update(visible=False)

# ✅ Start Gradio UI
with gr.Blocks(css="style.css") as demo:
    # Top spacer for centering effect
    gr.Markdown("", elem_id="top-spacer")

    with gr.Column():
        # Centered Title
        gr.Markdown("<h1 class='title'>🌲 AI Writing Assistant</h1>")

        # Empty space for fine-tuning vertical spacing
        gr.Markdown("", height=30)

        # Button container for selection
        with gr.Column(elem_id="button-container"):
            chain_button = gr.Button("📝 Structured Article Generation", scale=1)
            chat_button = gr.Button("💬 Conversational Mode", scale=1)

    # Bottom spacer for centering
    gr.Markdown("", elem_id="bottom-spacer")

    # 🔹 CHAIN EXECUTION UI (Initially Hidden)
    with gr.Column(visible=False) as chain_ui:
        gr.Markdown("## 📄 **Structured Article Generation**")
        start_button = gr.Button("Generate Persona")
        persona_display = gr.Textbox(label="Persona", interactive=False, lines=10, max_lines=10)

    # 🔹 CHAT UI (Initially Hidden)
    with gr.Column(visible=False) as chat_ui:
        gr.Markdown("## 💬 **Conversational Mode**")
        chatbox = gr.Chatbot(label="Chat Mode")
        user_input = gr.Textbox(label="Enter message", interactive=True, lines=2)
        send_button = gr.Button("Send")

    # 🔹 Button Click Actions to Show UI
    chain_button.click(show_chain_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])
    chat_button.click(show_chat_ui, outputs=[chain_ui, chat_ui, chain_button, chat_button])

    # ✅ Launch Gradio
    demo.launch()

---

Final Notes

1. Adjust height: 20vh; in style.css to move the content up or down.
2. No CSS overrides on Gradio’s layout → Keeps everything flexible.
3. You can fine-tune the height dynamically if needed.

This should now properly center the buttons and title without forcing height constraints. 🚀 Let me know if you need any more tweaks! 😊

ChatGPT

The issue with textboxes not fitting the text is likely due to the default lines parameter in gr.Textbox(). If a gr.Textbox() does not have enough lines, it will truncate the display of longer text, making it look improperly sized.

---

✅ Fix: Increase the lines Parameter

Modify your textboxes by adding lines=3 or more to fit the content properly.

---

🔹 Example Fix

In your Gradio script, update your textboxes like this:

location_input = gr.Textbox(
    label="Location",
    value=parameters["physical_context"]["location"],
    interactive=False,
    lines=3  # Set lines to 3 or more for better text fitting
)

landmarks_input = gr.Textbox(
    label="Landmarks",
    value=parameters["physical_context"]["landmarks"],
    interactive=False,
    lines=3
)

local_topo_geo_input = gr.Textbox(
    label="Local Topography",

Why This Fix Works

✅ Prevents text from getting cut off
✅ Allows long text to fully display without needing a scrollbar
✅ More flexible without forcing fixed heights

---

🚀 Next Steps

1. Update the lines=3 (or more) for all affected gr.Textbox() components.
2. Test the UI again – the textboxes should now properly fit the content.

Let me know if you need further tweaks! 😊

You

no answer for that?

ChatGPT

Yes! The issue is that Gradio textboxes default to a single-line height unless explicitly set with lines. Since your text is multi-line, it appears cut off or improperly sized.

---

✅ Fix: Increase lines and Use autogrow=True

Instead of manually guessing the height, Gradio provides autogrow=True, which makes textboxes dynamically adjust to content size.

---

🔹 Fix in Your Code

Update all gr.Textbox() components inside your chain_ui to include lines and autogrow, like this:

location_input = gr.Textbox(
    label="Location",
    value=parameters["physical_context"]["location"],
    interactive=False,
    lines=3,  # Ensure it starts at a reasonable height
    autogrow=True  # Dynamically expands based on text length
)

landmarks_input = gr.Textbox(
    label="Landmarks",
    value=parameters["physical_context"]["landmarks"],
    interactive=False,
    lines=3,
    autogrow=True
)

local_topo_geo_input = gr.Textbox(
    label="Local Topography",
    value=parameters["physical_context"]["local_topo_geo"],
    interactive=False,
    lines=3,
    autogrow=True
)

general_topo_geo_input = gr.Textbox(
    label="General Topography",
    value=parameters["physical_context"]["general_topo_geo"],
    interactive=False,
    lines=3,
    autogrow=True
)

species_range_input = gr.Textbox(
    label="Species Range",
    value=parameters["physical_context"]["species_range"],
    interactive=False,
    lines=3,
    autogrow=True
)

forest_composition_input = gr.Textbox(
    label="Forest Composition",
    value=parameters["physical_context"]["forest_composition"],
    interactive=False,
    lines=3,
    autogrow=True
)

soil_and_terrain_input = gr.Textbox(
    label="Soil & Terrain",
    value=parameters["physical_context"]["soil_and_terrain"],
    interactive=False,
    lines=3,
    autogrow=True
)

---

🚀 Why This Works

✅ lines=3 → Ensures a reasonable starting height
✅ autogrow=True → Dynamically resizes based on content length
✅ Fixes truncation issues → Text will always fully display

---

📌 Next Steps

1. Update all gr.Textbox() components to include lines=3 and autogrow=True.
2. Run the UI again → Textboxes should now automatically fit content.

This should solve the issue for good! 🚀 Let me know if you need any further adjustments. 😊

You

what if i have only the autogrow?

ChatGPT

If you use only autogrow=True without setting lines, the textboxes will still expand as needed, but their initial height will be very small (likely one line tall by default).

🚀 What Happens with Just autogrow=True?

✅ Textboxes will dynamically expand when text overflows
⚠️ Starts as a single line, which may look too small
✅ Removes the need to manually guess the height
⚠️ Might feel inconsistent if some textboxes start tiny and grow differently

---

Best Approach: Use Both autogrow=True and lines=3

If you only use autogrow=True, it will still work, but the textboxes might appear too small at first.
To balance good initial size and flexibility, it’s best to use:

gr.Textbox(value="Your long text here...", interactive=False, autogrow=True, lines=3)

🔥 Final Recommendation

Option	Behavior
autogrow=True only	✅ Dynamic resizing, but starts very small (1 line)
lines=3 only	✅ Starts bigger, but does not expand dynamically
lines=3, autogrow=True ✅	Best of both worlds: good initial size + dynamic resizing

---

📌 TL;DR

• If you want dynamic resizing only → Use autogrow=True
• If you want a reasonable starting size + resizing → Use autogrow=True, lines=3

Would you like to test both and see what works best for your UI? 🚀😊

You

autogrow is not a valid tag

ChatGPT

You’re right! autogrow is not a valid parameter in Gradio’s gr.Textbox(). That was my mistake. Instead, you can only control the height using lines. Gradio does not have a built-in autogrow feature for textboxes yet.

---

✅ Best Fix: Use lines for Initial Height

Since autogrow is not supported, the best way to ensure the text fits properly is to manually set lines to an appropriate value.

🔹 Fix in Your Code

Update your gr.Textbox() components like this:

location_input = gr.Textbox(
    label="Location",
    value=parameters["physical_context"]["location"],
    interactive=False,
    lines=5  # Adjust to a reasonable height
)

landmarks_input = gr.Textbox(
    label="Landmarks",
    value=parameters["physical_context"]["landmarks"],
    interactive=False,
    lines=4  # Adjust as needed
)

local_topo_geo_input = gr.Textbox(
    label="Local Topography",
    value=parameters["physical_context"]["local_topo_geo"],
    interactive=False,
    lines=5
)

general_topo_geo_input = gr.Textbox(
    label="General Topography",
    value=parameters["physical_context"]["general_topo_geo"],
    interactive=False,
    lines=5
)

species_range_input = gr.Textbox(
    label="Species Range",
    value=parameters["physical_context"]["species_range"],
    interactive=False,
    lines=5
)

forest_composition_input = gr.Textbox(
    label="Forest Composition",
    value=parameters["physical_context"]["forest_composition"],
    interactive=False,
    lines=5
)

soil_and_terrain_input = gr.Textbox(
    label="Soil & Terrain",
    value=parameters["physical_context"]["soil_and_terrain"],
    interactive=False,
    lines=5
)

---

❌ Why autogrow=True Doesn’t Work

• gr.Textbox() does not have an autogrow option.
• The closest alternative is setting lines to a reasonable value.
• If you want true auto-expanding, you need custom JavaScript & CSS, which is not supported natively in Gradio.

---

🚀 Final Recommendation

✅ Use lines=5 or adjust as needed for better text display.
✅ No need for autogrow, since it’s not supported in Gradio.
✅ Test different lines values to match the expected text length.

Would you like help fine-tuning the exact height values for your case? 😊

You

is it possible that previously the textboxes seemed to fit the text because the texts were loaded in the beginning whereas now they are dependant on what the user chooses at the beginning? and if yes is there a solution ? I DON’T WANT TO HARD SET LINE COUNT

ChatGPT

Yes, that is exactly what happened! Previously, the textboxes were preloaded with content when the UI was first rendered. Since Gradio automatically sizes textboxes based on initial content, they seemed to fit well.

Now that the textboxes start empty (depending on user input), Gradio does not resize them dynamically when content is added later.

---

🔥 Solution: Dynamically Resize Textboxes

Since Gradio does not have autogrow, here’s how you can make textboxes fit dynamically without hard-setting lines:

✅ Solution 1: Refresh Textbox After User Selection

You can force Gradio to refresh the textbox after content is updated, so it resizes based on the new content.

Modify your button click function to update the textboxes dynamically:

def update_textboxes():
    return gr.update(value=parameters["physical_context"]["location"]), \
           gr.update(value=parameters["physical_context"]["landmarks"]), \
           gr.update(value=parameters["physical_context"]["local_topo_geo"]), \
           gr.update(value=parameters["physical_context"]["general_topo_geo"]), \
           gr.update(value=parameters["physical_context"]["species_range"]), \
           gr.update(value=parameters["physical_context"]["forest_composition"]), \
           gr.update(value=parameters["physical_context"]["soil_and_terrain"])

chain_button.click(update_textboxes,
                   outputs=[location_input, landmarks_input, local_topo_geo_input,
                            general_topo_geo_input, species_range_input,
                            forest_composition_input, soil_and_terrain_input])

🔹 What This Does:

• When the user selects the mode, all textboxes are refreshed with the actual values.
• Gradio automatically resizes textboxes based on the content.
• No need to hard-set lines.

---

✅ Solution 2: Use scale to Give Textboxes More Space

Since Gradio textboxes do not resize dynamically, another approach is to make their parent columns flexible using scale.

Modify your gr.Row() like this:

with gr.Row():
    with gr.Column(scale=3):  # Allows dynamic resizing
        location_input = gr.Textbox(label="Location", interactive=False)
        landmarks_input = gr.Textbox(label="Landmarks", interactive=False)
        local_topo_geo_input = gr.Textbox(label="Local Topography", interactive=False)
        general_topo_geo_input = gr.Textbox(label="General Topography", interactive=False)
        species_range_input = gr.Textbox(label="Species Range", interactive=False)
        forest_composition_input = gr.Textbox(label="Forest Composition", interactive=False)
        soil_and_terrain_input = gr.Textbox(label="Soil & Terrain", interactive=False)
    with gr.Column(scale=1):
        species_input = gr.Textbox(label="Species", interactive=False)
        age_input = gr.Textbox(label="Age", interactive=False)
        max_age_input = gr.Textbox(label="Max Age", interactive=False)
        height_input = gr.Textbox(label="Height", interactive=False)
        max_height_input = gr.Textbox(label="Max Height", interactive=False)

🔹 Why This Works

• Instead of setting lines, we let Gradio handle dynamic sizing by giving textboxes more space in the layout.
• This prevents content from being cut off while keeping the UI flexible.

---

🚀 Best Approach

✅ Use Solution 1 to refresh textboxes after content is loaded.
✅ Combine with Solution 2 for better layout flexibility.
✅ No hard-coded lines, but text still fits dynamically.

This should fix your issue completely without breaking the layout! 🚀 Let me know if you need more tweaks! 😊

Refactoring: Separate Chain Logic into a Dedicated Script

To clean up your Gradio app script, we will:

1. Move all chain-related functions (LLM calls, RAG retrieval, execution logic) to a separate script.
2. Keep only the UI logic in the main script.
3. Import the chain functionality into the main script.

---

🚀 Step 1: Create a Separate Script for Chain Logic

Create a new Python file:
📄 chain_logic.py

This file will contain everything related to:

• LLM execution (execute_llm_call)
• Chain creation (create_chain, create_persona_chain)
• Parameter loading (get_step_inputs)
• Data handling (store_result_and_return)

import gradio as gr
from chain_logic import persona_workflow, full_workflow, parameters

# ✅ Start Gradio UI
with gr.Blocks() as demo:
    gr.Markdown("# 🌲 **Tree Correspondents Generator**")

    with gr.Row():

    start_button = gr.Button("Generate Persona")

    # ✅ Button Actions
    start_button.click(lambda: persona_workflow.invoke({}), outputs=[location_input])

    demo.launch()

---

🚀 Final Result

✅ chain_logic.py → Handles all LLM processing, RAG retrieval, and execution logic
✅ app.py → Only manages UI and user interactions
✅ Modular & Maintainable → Easy to debug and expand

---

🎯 Next Steps

1. Move chain_logic.py to your project directory.
2. Update app.py to import functions from chain_logic.py.
3. Run app.py and test! 🚀

This will make your project cleaner, modular, and scalable! 🎯 Let me know if you need further refinements! 😊

you oversimplified it. There are functions that have to do with the persona and the chain step execution that you completely omitted. But anyway

shouldn’t these be also enclosed in an init function or something?

i am primarily a c# programmer so some concepts in python confuse me.

ChatGPT

Yes, encapsulating initialization in a function is a good practice. In Python, we typically use an init function or a class to handle initialization when dealing with complex workflows. This makes your script more modular, maintainable, and reusable.

Since you’re coming from C#, I’ll explain it in a way that relates to what you’re used to (e.g., class constructors and encapsulation).

---

🔥 Why Use an init() Function or a Class?

• ✅ Encapsulation → Keeps initialization logic separate from execution.
• ✅ Modularity → Allows you to call init() anywhere without repeating code.
• ✅ Reusability → Makes it easier to refactor and debug.

---

🔹 Option 1: Use an init() Function

This is the simplest way to encapsulate setup logic.

Refactored chain_logic.py with init()

import yaml
import json
from langchain.prompts import PromptTemplate
from langchain.schema.runnable import RunnableSequence
from HF_API_Wrapper import HuggingFaceAPI
from rag_retrieve_meta import RagRetrieveWithMeta
from sentence_transformers import SentenceTransformer
from langchain_core.runnables import RunnableLambda
import os
import datetime
import re
from dotenv import load_dotenv

# ✅ Encapsulate Initialization in a Function
def init():
    # Load environment variables
    load_dotenv()
    HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

    if not HUGGINGFACE_TOKEN:
        raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

    # Load YAML Config
    with open("config_article.yml", "r", encoding="utf-8") as file:
        config = yaml.safe_load(file)

    api_info = config["API"]
    workflow_steps = config["workflow"]
    persona_steps = config["persona_workflow"]
    prompts = config["prompts"]
    rag_queries = config["rag"]
    parameters = config["parameters"]

    # Initialize Hugging Face LLM
    model_url = api_info["model_url"]
    api_token = HUGGINGFACE_TOKEN
    llm = HuggingFaceAPI(api_url=model_url, api_token=api_token)

    # Initialize RAG Retriever
    embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
    scientific_faiss = config['rag']['scientific']['faiss']
    scientific_meta = config['rag']['scientific']['embeddings']
    diary_faiss = config['rag']['diary']['faiss']
    diary_meta = config['rag']['diary']['embeddings']
    rag_retriever = RagRetrieveWithMeta(embedding_model, scientific_faiss, scientific_meta, diary_faiss, diary_meta)

    return {
        "llm": llm,
        "rag_retriever": rag_retriever,
        "parameters": parameters,
        "workflow_steps": workflow_steps,
        "persona_steps": persona_steps,
        "prompts": prompts,
        "rag_queries": rag_queries
    }

# ✅ Initialize System (Call `init()` once)
config_data = init()

# Now, you can access everything like this:
llm = config_data["llm"]
rag_retriever = config_data["rag_retriever"]
parameters = config_data["parameters"]
workflow_steps = config_data["workflow_steps"]
persona_steps = config_data["persona_steps"]
prompts = config_data["prompts"]
rag_queries = config_data["rag_queries"]

---

🔹 Option 2: Use a Class (More Like C#)

Since you’re familiar with C# classes and encapsulation, another approach is to use a class instead of an init() function.

Refactored chain_logic.py Using a Class

class ChainManager:
    def __init__(self):
        # Load environment variables
        load_dotenv()
        self.HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

        if not self.HUGGINGFACE_TOKEN:
            raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

        # Load YAML Config
        with open("config_article.yml", "r", encoding="utf-8") as file:
            self.config = yaml.safe_load(file)

        self.api_info = self.config["API"]
        self.workflow_steps = self.config["workflow"]
        self.persona_steps = self.config["persona_workflow"]
        self.prompts = self.config["prompts"]
        self.rag_queries = self.config["rag"]
        self.parameters = self.config["parameters"]

        # Initialize Hugging Face LLM
        self.llm = HuggingFaceAPI(api_url=self.api_info["model_url"], api_token=self.HUGGINGFACE_TOKEN)

        # Initialize RAG Retriever
        embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
        self.rag_retriever = RagRetrieveWithMeta(
            embedding_model,
            self.config['rag']['scientific']['faiss'],
            self.config['rag']['scientific']['embeddings'],
            self.config['rag']['diary']['faiss'],
            self.config['rag']['diary']['embeddings']
        )

    def get_workflow_steps(self):
        return self.workflow_steps

    def get_persona_steps(self):
        return self.persona_steps

    def get_llm(self):
        return self.llm

    def get_rag_retriever(self):
        return self.rag_retriever

✅ How to Use It in Your Main Script (app.py)

from chain_logic import ChainManager

# Initialize the chain manager
chain_manager = ChainManager()

# Accessing configurations
llm = chain_manager.get_llm()
rag_retriever = chain_manager.get_rag_retriever()
workflow_steps = chain_manager.get_workflow_steps()
persona_steps = chain_manager.get_persona_steps()

---

🤔 Which One Should You Use?

Method	Pros	Cons
✅ init() Function	Simple, quick to implement	Less structured
✅ Class (ChainManager)	More structured, follows OOP principles (like C#)	Slightly more complex

Since you are from a C# background, the class approach will feel more familiar (encapsulation, self is similar to this in C#). But if you prefer a simpler approach, the init() function will work just fine.

---

🎯 Final Thoughts

• If you want simplicity → Use init()
• If you prefer OOP structure (like C#) → Use ChainManager
• Both methods keep your code modular & maintainable ✅

Would you like help implementing either of these approaches in your full project? 😊🚀

You

so if i use inti then i have to return everything in a dictionary? there is no other way to have access these elemnts?

ChatGPT

If you use an init() function, returning a dictionary is not the only way to access the initialized variables. You can also use global variables inside the function. However, using global variables is generally not recommended for maintainability.

Alternatives to Returning a Dictionary

Here are three approaches:

✅ 1. Use init() with Global Variables (Not Recommended)

def init():
    global llm, rag_retriever, parameters, workflow_steps, persona_steps, prompts, rag_queries

    load_dotenv()
    HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

    if not HUGGINGFACE_TOKEN:
        raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

    # Load YAML Config
    with open("config_article.yml", "r", encoding="utf-8") as file:
        config = yaml.safe_load(file)

    api_info = config["API"]
    workflow_steps = config["workflow"]
    persona_steps = config["persona_workflow"]
    prompts = config["prompts"]
    rag_queries = config["rag"]
    parameters = config["parameters"]

    # Initialize Hugging Face LLM
    model_url = api_info["model_url"]
    llm = HuggingFaceAPI(api_url=model_url, api_token=HUGGINGFACE_TOKEN)

    # Initialize RAG Retriever
    embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
    rag_retriever = RagRetrieveWithMeta(
        embedding_model,
        config['rag']['scientific']['faiss'],
        config['rag']['scientific']['embeddings'],
        config['rag']['diary']['faiss'],
        config['rag']['diary']['embeddings']
    )

init()  # Call init once

# Now, you can use llm, rag_retriever, etc. anywhere in your script
print(llm, rag_retriever, parameters)  # Works globally

🔹 Pros:

• No need to return anything.
• You can use llm, rag_retriever, etc., anywhere after calling init().

🔹 Cons:

• Global variables make debugging harder (not encapsulated).
• Can cause conflicts in larger projects.

---

✅ 2. Use init() Without Returning a Dictionary (Use globals() Instead)

You can store everything in Python’s built-in globals() dictionary, making variables accessible anywhere.

def init():
    load_dotenv()
    HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

    if not HUGGINGFACE_TOKEN:
        raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

    # Load YAML Config
    with open("config_article.yml", "r", encoding="utf-8") as file:
        config = yaml.safe_load(file)

    api_info = config["API"]

    # Store variables in globals()
    globals()["parameters"] = config["parameters"]
    globals()["workflow_steps"] = config["workflow"]
    globals()["persona_steps"] = config["persona_workflow"]
    globals()["prompts"] = config["prompts"]
    globals()["rag_queries"] = config["rag"]
    globals()["llm"] = HuggingFaceAPI(api_url=api_info["model_url"], api_token=HUGGINGFACE_TOKEN)

    embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
    globals()["rag_retriever"] = RagRetrieveWithMeta(
        embedding_model,
        config['rag']['scientific']['faiss'],
        config['rag']['scientific']['embeddings'],
        config['rag']['diary']['faiss'],
        config['rag']['diary']['embeddings']
    )

init()  # Initialize once

# Now, you can use globals() anywhere
print(globals()["llm"], globals()["parameters"])  # Works globally

🔹 Pros:

• No need to return a dictionary.
• Encapsulates values in globals() instead of using explicit global variables.

🔹 Cons:

• Still relies on global state, which can lead to conflicts.
• Less readable than a class-based approach.

---

✅ 3. Best Practice: Use a Class (Encapsulation)

If you are comfortable with C#-style classes, this is the best approach:

class ChainManager:
    def __init__(self):
        load_dotenv()
        self.HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

        if not self.HUGGINGFACE_TOKEN:
            raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

        # Load YAML Config
        with open("config_article.yml", "r", encoding="utf-8") as file:
            self.config = yaml.safe_load(file)

        self.api_info = self.config["API"]
        self.workflow_steps = self.config["workflow"]
        self.persona_steps = self.config["persona_workflow"]
        self.prompts = self.config["prompts"]
        self.rag_queries = self.config["rag"]
        self.parameters = self.config["parameters"]

        # Initialize Hugging Face LLM
        self.llm = HuggingFaceAPI(api_url=self.api_info["model_url"], api_token=self.HUGGINGFACE_TOKEN)

        # Initialize RAG Retriever
        embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
        self.rag_retriever = RagRetrieveWithMeta(
            embedding_model,
            self.config['rag']['scientific']['faiss'],
            self.config['rag']['scientific']['embeddings'],
            self.config['rag']['diary']['faiss'],
            self.config['rag']['diary']['embeddings']
        )

    def get_llm(self):
        return self.llm

    def get_rag_retriever(self):
        return self.rag_retriever

    def get_parameters(self):
        return self.parameters

✅ Usage in Your Main Script (app.py)

from chain_logic import ChainManager

# Initialize the Chain Manager once
chain_manager = ChainManager()

# Access objects like this
llm = chain_manager.get_llm()
rag_retriever = chain_manager.get_rag_retriever()
parameters = chain_manager.get_parameters()

print(llm, rag_retriever, parameters)  # Works cleanly

🔹 Pros:

• Encapsulated (No globals needed).
• More like C# object-oriented design.
• Easier to maintain and extend.

🔹 Cons:

• Slightly more complex than a function.

---

🎯 Final Recommendation

Method	Pros	Cons
✅ init() + Return Dictionary	Clean & explicit	Requires accessing values via dictionary (config_data["llm"])
✅ init() + Global Variables	No dictionary needed	Uses global state (not recommended)
✅ init() + globals()	No need for explicit global variables	Still relies on global scope (harder to debug)
✅ Class-Based (ChainManager)	Best practice for scalability and encapsulation	Slightly more complex

If you are used to C#, go with Option 3 (Class-Based Approach) ✅.

If you want a simple solution, Option 1 (Dictionary Return) works fine too.

---

📌 TL;DR:

• Want structure? Use ChainManager class ✅
• Want simplicity? Use init() with a dictionary ✅
• Avoid global variables unless necessary ❌

---

Would you like me to help integrate one of these approaches into your full project? 😊🚀

You

if i use a class, is there a concept of public variables or do i have to use a function to access them?

ChatGPT

Yes, in Python, class variables are all “public” by default unless explicitly made private using an underscore (_) or double underscore (__). However, unlike C#, Python does not enforce access control, it just follows a convention.

---

🔹 How Public and Private Variables Work in Python Classes

Type	Python Syntax	Access Rule
Public Variable	self.my_variable	Can be accessed directly (obj.my_variable)
Protected Variable	self._my_variable	Conventionally private, but still accessible (obj._my_variable)
Private Variable	self.__my_variable	Name-mangled, cannot be accessed directly (obj.__my_variable fails)

---

✅ Example 1: Public vs Private Variables in Python

class ExampleClass:
    def __init__(self):
        self.public_var = "I am public"
        self._protected_var = "I am protected (but still accessible)"
        self.__private_var = "I am private (name-mangled)"

    def get_private_var(self):
        return self.__private_var  # Access private variable using a method

# Instantiate class
obj = ExampleClass()

# ✅ Public variable - can be accessed directly
print(obj.public_var)  # Output: I am public

# ⚠️ Protected variable - still accessible, but not recommended to access directly
print(obj._protected_var)  # Output: I am protected (but still accessible)

# ❌ Private variable - will raise an AttributeError
# print(obj.__private_var)  # This will fail!

# ✅ Correct way to access private variable
print(obj.get_private_var())  # Output: I am private (name-mangled)

---

✅ Example 2: Using a Class for Chain Management

In your case, if you want to follow Python best practices, public variables should be accessed directly and private variables should have getter functions.

🔹 Class Implementation for Chain Management

class ChainManager:
    def __init__(self):
        # Public variables (Accessible directly)
        self.parameters = None
        self.workflow_steps = None
        self.persona_steps = None
        self.prompts = None
        self.rag_queries = None
        self.llm = None
        self.rag_retriever = None

        # Load configurations
        self._initialize_config()

    def _initialize_config(self):
        """Private method to load configurations."""
        from dotenv import load_dotenv
        import os
        import yaml
        from HF_API_Wrapper import HuggingFaceAPI
        from sentence_transformers import SentenceTransformer
        from rag_retrieve_meta import RagRetrieveWithMeta

        # Load environment variables
        load_dotenv()
        HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

        if not HUGGINGFACE_TOKEN:
            raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

        # Load YAML Config
        with open("config_article.yml", "r", encoding="utf-8") as file:
            config = yaml.safe_load(file)

        self.parameters = config["parameters"]
        self.workflow_steps = config["workflow"]
        self.persona_steps = config["persona_workflow"]
        self.prompts = config["prompts"]
        self.rag_queries = config["rag"]

        # Initialize Hugging Face LLM
        self.llm = HuggingFaceAPI(api_url=config["API"]["model_url"], api_token=HUGGINGFACE_TOKEN)

        # Initialize RAG Retriever
        embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
        self.rag_retriever = RagRetrieveWithMeta(
            embedding_model,
            config['rag']['scientific']['faiss'],
            config['rag']['scientific']['embeddings'],
            config['rag']['diary']['faiss'],
            config['rag']['diary']['embeddings']
        )

    # ✅ Public getter functions for encapsulation
    def get_llm(self):
        return self.llm

    def get_rag_retriever(self):
        return self.rag_retriever

    def get_parameters(self):
        return self.parameters

---

✅ Example Usage in app.py

Now, you can import ChainManager and use it in your Gradio app:

from chain_logic import ChainManager

# Initialize once
chain_manager = ChainManager()

# Direct access to public variables
print(chain_manager.parameters)  # ✅ Works directly

# Access using functions (optional for encapsulation)
llm = chain_manager.get_llm()
rag_retriever = chain_manager.get_rag_retriever()

---

🤔 Should You Use Direct Access or Getter Methods?

Access Type	Pros	Cons
Direct Access (self.parameters)	Simple, readable	No encapsulation
Getter Method (get_parameters())	Encapsulated, flexible	Slightly more boilerplate

🔹 For simple cases, direct access (chain_manager.parameters) is fine.
🔹 For long-term maintainability, getter methods (chain_manager.get_parameters()) are better.

---

🎯 Final Answer: Use Public Variables & Getter Methods

If you’re coming from C#, you might be used to properties like:

public string Parameters { get; private set; }

In Python, you can directly access public variables, but for better structure, use getter methods.

Would you like help optimizing how the class interacts with your chain execution? 🚀😊

You

according to what you said above instead of this

Access using functions (optional for encapsulation)

llm = chain_manager.get_llm() rag_retriever = chain_manager.get_rag_retriever()

i can do this llm = chain_manager.llm rag_retriever = chain_manager.rag_retriever

ChatGPT

Yes! You can directly access the variables like this:

llm = chain_manager.llm
rag_retriever = chain_manager.rag_retriever

Why Does This Work?

• In Python, all instance variables (self.variable_name) are public by default.
• Since llm and rag_retriever are defined inside ChainManager as instance variables (self.llm, self.rag_retriever), they can be accessed directly.

Direct Access vs Getter Method

Approach	Syntax	Pros	Cons
Direct Access	llm = chain_manager.llm	✅ Simple, readable	❌ Less encapsulated
Getter Method	llm = chain_manager.get_llm()	✅ Encapsulated (good for future changes)	❌ Slightly more boilerplate

When to Use Direct Access vs Getters

1. ✅ Use direct access (chain_manager.llm) if you just need to read values.
2. ✅ Use a getter (chain_manager.get_llm()) if you need extra logic before returning the value (e.g., lazy initialization, validation, caching).

---

Example of When a Getter Is Useful

Imagine you only want to initialize llm when it’s first accessed.
You can modify the getter like this:

class ChainManager:
    def __init__(self):
        self._llm = None  # Delayed initialization
        self._initialize_config()

    def _initialize_config(self):
        from dotenv import load_dotenv
        import os
        import yaml
        from HF_API_Wrapper import HuggingFaceAPI

        load_dotenv()
        HUGGINGFACE_TOKEN = os.getenv("HUGGINGFACE_TOKEN")

        if not HUGGINGFACE_TOKEN:
            raise ValueError("HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.")

        # Load config
        with open("config_article.yml", "r", encoding="utf-8") as file:
            config = yaml.safe_load(file)

        self.api_info = config["API"]

    def get_llm(self):
        """Lazy initialization: LLM is only created when first accessed"""
        if self._llm is None:
            print("Initializing LLM...")
            from HF_API_Wrapper import HuggingFaceAPI
            self._llm = HuggingFaceAPI(api_url=self.api_info["model_url"], api_token=os.getenv("HUGGINGFACE_TOKEN"))
        return self._llm

🔹 Now, the LLM isn’t created immediately on class instantiation but only when needed.

chain_manager = ChainManager()
llm = chain_manager.get_llm()  # ✅ LLM initializes only now

---

🎯 Final Answer

Yes, you can do:

llm = chain_manager.llm
rag_retriever = chain_manager.rag_retriever

But if you need delayed initialization or additional logic, use:

llm = chain_manager.get_llm()

Would you like help implementing lazy initialization for other parts of your chain? 🚀😊

You

when defining a global variable is it global in the function the .py script or the class?

ChatGPT

Understanding Scope in Python: Global Variables in Functions, Scripts, and Classes

The scope of a global variable depends on where and how it’s defined. Let’s break it down.

---

🔹 1. Global Variable in a Function

If you define a variable inside a function without using global, it is local to the function.

def my_function():
    x = 10  # Local variable, only accessible inside this function
    print(x)

my_function()
# print(x)  # ❌ This would raise an error because x is not global

✅ x exists only inside my_function().
❌ Cannot be accessed outside the function.

---

🔹 2. Making a Function Variable Global

If you want a variable inside a function to be global, use the global keyword:

def my_function():
    global x  # Declaring x as a global variable
    x = 10  # Now x is accessible outside the function

my_function()
print(x)  # ✅ This works because x is now global

✅ x is now global in the entire script after calling my_function().

⚠️ Best practice: Avoid using global inside functions unless necessary.

---

🔹 3. Global Variables in a Python Script

A variable defined at the top level of a Python script (outside any function or class) is automatically global within that script.

# Global variable
api_key = "my_secret_key"

def get_key():
    print(api_key)  # ✅ Can access global variable inside a function

get_key()
print(api_key)  # ✅ Can be accessed anywhere in this script

✅ api_key is accessible anywhere in the script.
❌ But it is not automatically available in another script unless imported.

---

🔹 4. Global Variables in a Class

A variable defined at the class level is shared across all instances unless overridden.

class MyClass:
    class_variable = "I am shared"  # ✅ Class-level global variable

    def __init__(self, name):
        self.name = name  # Instance variable (specific to an object)

# Accessing class variable
print(MyClass.class_variable)  # ✅ Accessible without creating an object

# Creating instances
obj1 = MyClass("Alice")
obj2 = MyClass("Bob")

print(obj1.class_variable)  # ✅ Accessible via an instance
print(obj2.class_variable)  # ✅ Same value for all instances

# Changing class variable affects all instances
MyClass.class_variable = "Changed"
print(obj1.class_variable)  # ✅ Now it's "Changed"
print(obj2.class_variable)  # ✅ Also "Changed"

✅ Class variables are shared across all instances.
✅ Instance variables (self.name) are specific to each object.

---

🔹 5. Global Variables in a Class Method

If you define a variable inside a method, it is local unless declared global.

class MyClass:
    def set_global(self):
        global my_var
        my_var = "Now I'm global"

obj = MyClass()
obj.set_global()
print(my_var)  # ✅ Accessible anywhere after being set

✅ my_var is now global outside the class because of global my_var.

---

🔹 6. Global Variables Across Different Scripts

If you define a global variable in one script (config.py), you can access it in another script (app.py) by importing it.

📄 config.py

api_key = "my_secret_key"

📄 app.py

import config  # Import the script

print(config.api_key)  # ✅ Access global variable from config.py

✅ The variable remains global in config.py but must be accessed using config.api_key.

---

🔹 Final Answer: Where Is a Global Variable Actually Global?

Where Global is Defined	Where It’s Accessible
Inside a function (without global)	❌ Only inside that function
Inside a function (with global)	✅ Everywhere in the script after the function runs
At the top level of a script	✅ Everywhere in that script
Inside a class (as a class variable)	✅ Shared across all instances of the class
Inside a class method (with global)	✅ Becomes a global variable after the method is called
In a separate script (imported)	✅ Accessible using module_name.variable

---

🎯 Best Practice Recommendation

1. ✅ Use script-level global variables for config values (api_key = "xyz").
2. ✅ Use class variables if they are shared across all instances (MyClass.class_var).
3. ✅ Use instance variables for object-specific values (self.name = "Alice").
4. ❌ Avoid using global inside functions unless necessary.

Problem: chain_manager Is Not Initialized Properly

You’re encountering an issue where chain_manager appears empty when calling its methods.

🔹 Issue 1: chain_manager is None Before UI Initialization

Problem

# ==== Declare managers =======
chain_manager = None
chat_manager = None

Here, you set chain_manager = None, and later in the UI:

start_button.click(
    chain_manager.initialize_persona,  # ❌ chain_manager is None here
    inputs=[],
    outputs=[persona_display, refinement_elements, refinement_prompt_box]
)

This causes an error because chain_manager is not instantiated before trying to use it.

Solution: Instantiate ChainManager at the Beginning

Modify your code like this:

# ✅ Properly initialize `chain_manager`
chain_manager = ChainManager()

Now, chain_manager is an actual object before the UI runs.

---

🔹 Issue 2: chain_manager is Reinitialized Inside a Function

Inside show_chain_ui(), you create a new instance of ChainManager, but this does not update the global chain_manager.

def show_chain_ui():
    chain_manager = ChainManager()  # ❌ This creates a new instance but does not update the global one
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

Why is this a problem?

• This creates a new local variable chain_manager inside the function, but it does not update the global one.
• The chain_manager in the main script remains None, causing errors.

Solution: Use the global keyword or return the instance.

Option 1: Update the Global Variable

def show_chain_ui():
    global chain_manager  # ✅ This makes sure we modify the global instance
    chain_manager = ChainManager()  # ✅ Now this updates the global variable
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

Option 2: Return the Instance and Store It Modify the button action:

chain_button.click(lambda: show_chain_ui() or chain_manager.init_chains(), outputs=[chain_ui, chat_ui, base_ui])

This ensures that init_chains() runs after chain_manager is created.

---

🔹 Final Fix: Correctly Initialize and Manage chain_manager

1️⃣ Initialize chain_manager Properly

# ✅ Create the object at the beginning
chain_manager = ChainManager()

2️⃣ Update show_chain_ui() to Modify Global chain_manager

def show_chain_ui():
    global chain_manager  # ✅ Modify the existing instance instead of creating a local one
    chain_manager = ChainManager()
    chain_manager.init_chains()  # ✅ Initialize workflows after creation
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

3️⃣ Ensure chain_manager is Available Before Calling Methods

Modify Gradio button actions:

start_button.click(
    lambda: chain_manager.initialize_persona() if chain_manager else None,
    inputs=[],
    outputs=[persona_display, refinement_elements, refinement_prompt_box]
)

This ensures chain_manager exists before calling a method.

---

🚀 Final Working Code Summary

# ✅ Initialize ChainManager at the start
chain_manager = ChainManager()

def show_chain_ui():
    global chain_manager  # ✅ Modify the global variable
    chain_manager = ChainManager()
    chain_manager.init_chains()  # ✅ Initialize chains
    return gr.update(visible=True), gr.update(visible=False), gr.update(visible=False)

# ✅ Ensure `chain_manager` is initialized before using
start_button.click(
    lambda: chain_manager.initialize_persona() if chain_manager else None,
    inputs=[],
    outputs=[persona_display, refinement_elements, refinement_prompt_box]
)

---

🎯 Summary: Why This Works

✔ chain_manager is properly initialized at the start.
✔ show_chain_ui() correctly updates the global instance.
✔ Button actions ensure chain_manager is ready before calling methods.

ChatGPT

Understanding the Error

Gradio expects the functions save_history and respond to accept a certain number of arguments. The error messages indicate that:

1. save_history() is expected to take 0 arguments, but Gradio is passing 1 argument (chatbox).
2. respond(user_input) is expected to take 1 argument, but Gradio is passing 2 arguments (prompt_box and chatbox).

---

🔹 Issue 1: save_history() Receives an Unexpected Argument

Problem

download_btn.click(chain_manager.save_history, inputs=[chatbox], outputs=[file_output])

• The save_history method does not take any arguments.
• Gradio is passing chatbox as an argument, but the function does not expect it.

Solution: Use a lambda to ignore arguments

Modify the function call like this:

download_btn.click(lambda _: chain_manager.save_history(), inputs=[], outputs=[file_output])

• The _ argument captures the extra argument (which we ignore).
• Now chain_manager.save_history() is called without any arguments.

---

🔹 Issue 2: respond(user_input) Receives an Extra Argument

Problem

prompt_box.submit(chain_manager.respond, [prompt_box, chatbox], chatbox)

• The respond method expects 1 argument (user_input).
• Gradio passes 2 arguments: prompt_box (user input) and chatbox (chat history).

Solution: Modify respond() to Accept Two Arguments

Modify respond to handle two arguments (user_input, history):

def respond(self, user_input, history):
    updated_history = history + [(user_input, f"Response to: {user_input}")]  # Append response
    return updated_history

Then, update the button action:

prompt_box.submit(chain_manager.respond, [prompt_box, chatbox], chatbox)

This ensures that:

• user_input comes from prompt_box.
• history comes from chatbox.

---

🚀 Final Fix

Corrected Gradio Calls:

# ✅ Fix save_history (ignore arguments)
download_btn.click(lambda _: chain_manager.save_history(), inputs=[], outputs=[file_output])

# ✅ Fix respond (pass both user input and history)
prompt_box.submit(chain_manager.respond, [prompt_box, chatbox], chatbox)

Corrected respond() Function:

def respond(self, user_input, history):
    updated_history = history + [(user_input, f"Response to: {user_input}")]  # Append response
    return updated_history

---

🎯 Summary

Issue	Problem	Solution
save_history() receives an extra argument	Gradio is passing chatbox	Use lambda _: chain_manager.save_history()
respond() receives 2 arguments instead of 1	Needs both user_input and history	Modify function to accept history

This will fix your issue completely! 🚀 Let me know if you need more help. 😊

Issue: Chatbox in Article Generation Process is Not Updating

Your issue is that although the chain responses are generated, they are not displayed in the chatbox (Tree's Perspective Chat). This likely means:

1. The function process_step is not updating the chatbox correctly.
2. The outputs of process_step are not formatted properly for Gradio.
3. The chatbox might not be receiving the updated history.

---

🔹 Issue 1: process_step is Not Appending to the Chatbox

Your process_step method returns the new chat history, but it might not be updating the chatbox correctly.

✅ Fix: Ensure History is Stored Properly

Modify process_step to ensure history updates properly:

def process_step(self, user_input, history):
    # 🔹 If All Steps Are Completed
    if self.step_index >= len(self.workflow_steps):
        return history + [("✅ Generation Process Complete!", "")], None

    step_name = self.workflow_steps[self.step_index]["name"]
    self.step_index = self.define_step_index(self.step_index)

    # 🔹 Handle LLM Steps (User Can Modify Prompt)
    config_template = self.prompts[self.workflow_steps[self.step_index]["prompt"]]["template"]
    prompt_template = user_input if user_input else config_template
    inputs = {key: self.generated_inputs.get(key, self.parameters.get(key, "")) for key in self.workflow_steps[self.step_index]["inputs"]}
    filled_prompt = prompt_template.format(**inputs)

    # Store user-modified prompt
    self.user_inputs[step_name] = prompt_template

    # 🔹 Get LLM Response
    response = self.full_workflow.steps[self.step_index].invoke({}, _prompt=filled_prompt)
    response_text = response[f"{self.workflow_steps[self.step_index]['output']}"]

    # 🔹 Append new response to history
    updated_history = history + [(prompt_template, response_text)]

    # 🔹 Move to Next Step
    self.step_index += 1

    # 🔹 Prepare Next Step Prompt
    next_filled_prompt = None
    if self.step_index < len(self.workflow_steps):
        self.step_index = self.define_step_index(self.step_index)
        next_step = self.workflow_steps[self.step_index]
        if next_step["type"] == "LLM":
            next_filled_prompt = self.prompts[next_step["prompt"]]["template"]

    return updated_history, next_filled_prompt

Changes: ✔ Ensures history is updated.
✔ Ensures response_text is correctly extracted.
✔ Moves step_index forward correctly.
✔ Ensures next_filled_prompt is returned properly.

---

🔹 Issue 2: next_step_btn.click is Not Updating the Chatbox

Currently, your next_step_btn.click function does not correctly update chatbox:

next_step_btn.click(
    chain_manager.process_step,
    inputs=[prompt_box, chatbox],
    outputs=[chatbox, prompt_box]  # ❌ Might not update chatbox correctly
)

✅ Fix: Ensure it properly updates chatbox

next_step_btn.click(
    lambda user_input, history: chain_manager.process_step(user_input, history),
    inputs=[prompt_box, chatbox],
    outputs=[chatbox, prompt_box]  # ✅ Ensures chatbox gets updated
)

---

🔹 Issue 3: Chat History is Not Persisted Correctly

If your chat history (chatbox) is not persisting between steps, you may need to store it in self.history:

✅ Fix: Store history in ChainManager

Modify process_step to update self.history:

def process_step(self, user_input, history):
    if self.step_index >= len(self.workflow_steps):
        return history + [("✅ Generation Process Complete!", "")], None

    step_name = self.workflow_steps[self.step_index]["name"]
    self.step_index = self.define_step_index(self.step_index)

    config_template = self.prompts[self.workflow_steps[self.step_index]["prompt"]]["template"]
    prompt_template = user_input if user_input else config_template
    inputs = {key: self.generated_inputs.get(key, self.parameters.get(key, "")) for key in self.workflow_steps[self.step_index]["inputs"]}
    filled_prompt = prompt_template.format(**inputs)

    self.user_inputs[step_name] = prompt_template

    response = self.full_workflow.steps[self.step_index].invoke({}, _prompt=filled_prompt)
    response_text = response[f"{self.workflow_steps[self.step_index]['output']}"]

    updated_history = history + [(prompt_template, response_text)]
    self.history = updated_history  # ✅ Store updated history

    self.step_index += 1

    next_filled_prompt = None
    if self.step_index < len(self.workflow_steps):
        self.step_index = self.define_step_index(self.step_index)
        next_step = self.workflow_steps[self.step_index]
        if next_step["type"] == "LLM":
            next_filled_prompt = self.prompts[next_step["prompt"]]["template"]

    return updated_history, next_filled_prompt

Now, self.history is always updated.

---

🎯 Summary: Fixing Chatbox Not Updating

Issue	Problem	Solution
process_step not updating chatbox	history is not correctly appended	Ensure updated_history is returned and stored
next_step_btn.click not properly passing inputs	Gradio needs correct input/output mapping	Use lambda to correctly map inputs
Chat history (chatbox) not persisting	history is not stored properly in ChainManager	Store history inside self.history

✅ Now, chatbox will correctly update with each chain step! 🚀 Let me know if you need further clarifications! 😊

You

ok i figured it out. Now i have another question. For the article generation workflow. I am reading evertyhing regarding the chain from a yml file. That is all of the paramaters, the chain steps and the llm and rag prompts. Is it possible to expose an entry for the user to upload a yml file and repopulate/refresh the chain and all of the components and then run the generationa gain?

ChatGPT

Yes! You can allow the user to upload a YAML file and dynamically refresh the entire chain configuration without restarting the app. Here’s how you can achieve this:

---

🔹 Steps to Implement

1. Add a file upload button in Gradio.
2. Process the uploaded YAML file and update ChainManager.
3. Reinitialize the chain using the new YAML data.
4. Allow the user to regenerate the article using the updated config.

---

🔹 Implementation Plan

1️⃣ Add File Upload UI in Gradio

Modify your Gradio UI to include a file uploader:

yaml_upload = gr.File(label="Upload New YAML Config", type="file")
update_chain_btn = gr.Button("Update Chain with New Config")

---

2️⃣ Define a Function to Load and Update YAML

Create a method inside ChainManager to load the YAML file:

def load_custom_config(self, yaml_path):
    """Loads a new YAML configuration from the uploaded file and reinitializes the chain."""
    try:
        with open(yaml_path, "r", encoding="utf-8") as file:
            new_config = yaml.safe_load(file)

        # Update the configuration parameters
        self.parameters = new_config["parameters"]
        self.workflow_steps = new_config["workflow"]
        self.persona_steps = new_config["persona_workflow"]
        self.prompts = new_config["prompts"]
        self.rag_queries = new_config["rag"]

        # Reinitialize the chain components
        self.init_chains()

        return "✅ Chain Updated Successfully! Ready to generate a new article."

    except Exception as e:
        return f"❌ Error: {str(e)}"

---

3️⃣ Connect File Upload & Update Chain

Modify your Gradio setup to trigger the update when the user uploads a YAML file:

yaml_upload.upload(
    lambda file: chain_manager.load_custom_config(file.name),
    inputs=[yaml_upload],
    outputs=[]
)

update_chain_btn.click(
    lambda: chain_manager.init_chains(),
    inputs=[],
    outputs=[]
)

🔹 How It Works

1. User uploads a new YAML file → yaml_upload.upload triggers load_custom_config()
2. New YAML is parsed and updates the chain.
3. User clicks Update Chain → Calls init_chains() to reinitialize everything.
4. User starts article generation with the new settings.

---

🎯 Benefits of This Approach

✔ No need to restart the app
✔ Fully dynamic chain updates
✔ Allows experimentation with different configurations
✔ Keeps Gradio UI responsive

Now, your article generation can be customized on-the-fly! 🚀 Let me know if you need further refinements! 😊

You

How can i make these much shorter? one line

ChatGPT

To make the YAML file upload and Update Chain button appear on one line instead of being stacked, you should wrap them in a gr.Row() container.

---

✅ Solution: Use gr.Row() to Keep Them Side-by-Side

Modify your Gradio layout like this:

# YAML Upload Section - Put in a Row to Keep Them on One Line
with gr.Row():
    yaml_upload = gr.File(label="Upload New YAML Config", type="file", interactive=True, scale=1)
    update_chain_btn = gr.Button("Update Chain with New Config", scale=1)

---

🔹 Explanation

• gr.Row() → Ensures elements are placed horizontally instead of stacking.
• scale=1 → Ensures both elements take equal space.
• interactive=True → Ensures file input is clickable.

---

🚀 Expected Outcome

This should now display both elements in a single row, making the UI more compact and structured. 🎯

Let me know if you need further adjustments! 😊

ok i now have this code for the chat mode. I actually want to keep the persona generation as is from the article mode and use it in the chat prompts. but can you help me convert thi into a class and then make the gradio ui?

===== Load env file =========

load_dotenv() HUGGINGFACE_TOKEN = os.getenv(“HUGGINGFACE_TOKEN”)

if not HUGGINGFACE_TOKEN: raise ValueError(“HUGGINGFACE_TOKEN is not set! Make sure to define it in .env.”)

===== Load YAML Config =====

api_info = config[“API”] prompts = config[“prompts”]

✅ Dictionary to Store Dynamically Generated Inputs

generated_inputs = {}

===== Initialize Hugging Face LLM =====

model_url = api_info[“model_url”] api_token = HUGGINGFACE_TOKEN llm = HuggingFaceAPI(api_url=model_url, api_token=api_token)

===== INITIALIZE RAG ===================================

========================================================

Load embedding model

embedding_model = SentenceTransformer(‘all-MiniLM-L6-v2’)

Load indices when needed

the rag workflow is old. it will be replaced with the new version i have in the chainmanager

ChatGPT

Got it! I’ll convert your Chat Mode into a class while integrating the persona generation from your existing ChainManager class. I’ll also remove the outdated RAG workflow and ensure that the new version from ChainManager is used instead.

---

🔹 Plan

• Create a ChatManager class.
• Use the ChainManager for persona generation and RAG retrieval.
• Keep the question classification, tree response, and memory storage logic within ChatManager.
• Provide a Gradio UI to interact with the tree.

🔹 Changes & Improvements

1. Created ChatManager class

   • Handles persona-based chat, multi-hop retrieval, and LLM-powered responses.
   • Uses ChainManager to keep persona consistency between modes.

2. Replaced Old RAG Retrieval with ChainManager

   • Uses self.chain_manager.rag_retriever.rag_wrapper(...).

3. Encapsulated Memory & Thought Processing

   • Uses LangChain ConversationBufferMemory for chat history.

4. Gradio UI for Chat

   • Includes text input, a chatbot display, and a send button.

---

🚀 How it Works

1. When a journalist asks a question, it’s classified into multi-hop categories.
2. If needed, RAG retrieves information from ChainManager.
3. The tree generates “thoughts” before responding.
4. The tree challenges the journalist and provides an insightful answer.
5. Chat history is stored, improving context-awareness over time.

---

🔹 Next Steps

Would you like to integrate this into your existing UI, or should this remain separate as a chat module? 🚀😊

You

shouldn’t the chat_with_tree function change to be incorporated with gradio functionality?

ChatGPT

Yes! The chat_with_tree function was originally a CLI-based chat loop, but since we’re now using Gradio, we should replace it with a proper Gradio-compatible function that:

• Takes user input via a text box.
• Generates responses from the tree.
• Stores chat history to maintain context.
• Displays messages in Gradio’s Chatbot component.

🔹 What Changed?

1️⃣ chat_with_tree() is now Gradio-compatible

• Instead of a CLI loop, the generate_tree_response() method is triggered when the user submits a message in the UI.
• The chat history is passed and updated dynamically.

2️⃣ Gradio UI

• Chatbot component (gr.Chatbot) to display messages.
• Text input field for user messages.
• “Send” button to generate responses.
• “Reset Chat” button to clear conversation history.

3️⃣ Automatic History Updates

• Chat history is stored and displayed in gr.Chatbot format.
• The tree’s memory persists throughout the conversation.

---

🔹 Next Steps

• Would you like to merge this UI with your existing Article Generation UI?
• Or keep it separate as a dedicated Chat Mode? 🚀😊

You can use Python’s split() method and list slicing to extract the first three words from a sentence. Here’s how:

def first_three_words(sentence):
    words = sentence.split()  # Split the sentence into a list of words
    return " ".join(words[:3])  # Join the first three words back into a string

# Example usage
sentence = "The quick brown fox jumps over the lazy dog"
result = first_three_words(sentence)
print(result)  # Output: "The quick brown"

Explanation:

1. split() converts the sentence into a list of words.
2. words[:3] extracts the first three words.
3. " ".join(...) joins them back into a string.

⚠ Edge Case Handling:

• If the sentence has less than three words, it will return whatever words exist.

Example:

print(first_three_words("Hello world"))  # Output: "Hello world"
print(first_three_words("Hi"))  # Output: "Hi"

You

and if it is three words with spaces inbetween can it be used as a dictionary key? or will there be an issue with the spaces?

ChatGPT

Yes, a three-word string with spaces in between can be used as a dictionary key in Python. However, there are some things to consider:

Using a Multi-Word String as a Dictionary Key

Python dictionaries allow strings with spaces as keys without any issue:

my_dict = {}
key = "The quick brown"
my_dict[key] = "A fox jumps over"

print(my_dict)  # {'The quick brown': 'A fox jumps over'}
print(my_dict["The quick brown"])  # A fox jumps over

Potential Issues & Best Practices

1. Whitespace Handling:

   • If the key is extracted dynamically from user input, ensure that leading/trailing spaces are removed using .strip().
   • Example:

     key = "  The quick brown  ".strip()  # "The quick brown"

2. Dictionary Key Consistency:

   • If keys are generated from different sources (e.g., user input, file parsing), normalize them by:
     • Converting to lowercase (.lower())
     • Removing extra spaces (" ".join(key.split()))
   • Example:

     key = "  The   quick   brown  "
     normalized_key = " ".join(key.split()).lower()  # "the quick brown"

3. Lookups & Matching Issues:

   • Since dictionary keys must match exactly, ensure you’re using a consistent format.
   • Example:

     my_dict = {"The quick brown": "Fox"}
     print(my_dict.get("The quick brown"))  # ✅ Returns 'Fox'
     print(my_dict.get("the quick brown"))  # ❌ Returns None (case-sensitive)

4. Alternative Approach: Using Tuples as Keys:

   • Instead of a string, store the three words as a tuple:

     my_dict = {("The", "quick", "brown"): "Fox"}
     print(my_dict[("The", "quick", "brown")])  # Fox

   • This avoids issues with spaces and enforces word separation.

Conclusion

• Strings with spaces work fine as dictionary keys.
• Normalize input to avoid unexpected mismatches.
• Consider tuples for more structured keys.

You

can you show me how to replace the spaces with underscores?

ChatGPT

Yes! You can replace spaces with underscores using Python’s .replace() or " ".join().replace(). Here’s how:

Replace Spaces with Underscores

text = "The quick brown"
key = text.replace(" ", "_")  # Replaces spaces with underscores
print(key)  # Output: The_quick_brown

---

Normalize and Replace Spaces in a Sentence

To ensure proper formatting (removing extra spaces and converting to lowercase):

text = "  The   quick   brown  "
normalized_key = "_".join(text.split()).lower()  # Removes extra spaces & replaces with underscores
print(normalized_key)  # Output: the_quick_brown

---

Using It as a Dictionary Key

my_dict = {}
key = "The quick brown".replace(" ", "_")  # Convert key
my_dict[key] = "Fox jumps over"

print(my_dict)  # {'The_quick_brown': 'Fox jumps over'}
print(my_dict["The_quick_brown"])  # Fox jumps over

✅ GRADIO UI: Chat Mode

=======================================================

def create_chat_ui(chat_manager): with gr.Blocks() as chat_ui: gr.Markdown(”## 🌲 Tree Correspondents / 💬 Interview”)

    chatbox = gr.Chatbot(label="Tree's Perspective Chat", elem_id="custom_chatbox")

    with gr.Row():
        user_input = gr.Textbox(label="Enter message", interactive=True, lines=2)
        send_button = gr.Button("Send")
        reset_button = gr.Button("Reset Chat")

    # Button action: Process user input and update chatbox
    send_button.click(
        chat_manager.generate_tree_response,
        inputs=[user_input, chatbox],
        outputs=[chatbox, user_input],
    )

    # Reset chat history
    reset_button.click(
        chat_manager.reset_chat,
        inputs=[],
        outputs=[chatbox],
    )

    # Allow enter key submission
    user_input.submit(chat_manager.generate_tree_response, [user_input, chatbox], [chatbox, user_input])

return chat_ui

can i edit the height of the chatbox?

ChatGPT

Yes! You can edit the height of the Gradio Chatbot by specifying the height parameter in the gr.Chatbot() component.

Modify the Chatbox Height

chatbox = gr.Chatbot(label="Tree's Perspective Chat", elem_id="custom_chatbox", height=500)  # Adjust height as needed

This will set the height of the chatbox to 500 pixels.

---

Custom Styling with CSS

If you want more control over the chatbox height, you can use CSS by applying a custom elem_id and defining the styles in a separate CSS file or inline.

1️⃣ Assign elem_id to the chatbox

chatbox = gr.Chatbot(label="Tree's Perspective Chat", elem_id="custom_chatbox")

2️⃣ Define the CSS Rule (inside style.css)

#custom_chatbox {
    height: 500px !important;  /* Set the height */
    max-height: 600px;         /* Prevent it from growing too large */
    overflow-y: auto;          /* Enable scrolling */
}

3️⃣ Load the Custom CSS in Gradio

def custom_css():
    return gr.HTML('<style>' + open("style.css").read() + '</style>')

And call custom_css() inside your Gradio UI.

---

Alternative: Dynamic Height with max-height

If you want the chatbox to grow dynamically but not exceed a certain height:

#custom_chatbox {
    min-height: 300px;  /* Minimum height */
    max-height: 600px;  /* Maximum height */
    overflow-y: auto;   /* Scroll when it exceeds max-height */
}

Let me know if you need further adjustments! 🚀

ChatGPT

The error “An event handler (generate_tree_response) didn’t receive enough output values (needed: 2, received: 1)” means that Gradio expects two output values, but the function generate_tree_response only returns one.

---

🔹 How to Fix It?

Your generate_tree_response function should return two values:

1. Updated chat history (for chatbox).
2. Cleared input field (so the input box resets after sending a message).

✅ Fix in generate_tree_response

Modify your generate_tree_response function inside ChatManager:

def generate_tree_response(self, question, history):
    # Step 1: Classify Question (Possibly Multi-Hop)
    process_log = {}
    process_log['journalist_question'] = question

    classifications = self.classify_question(question, self.prompts["hop_classification"]["template"])
    process_log['classification'] = classifications

    # Step 2: Retrieve Relevant Knowledge (Categorized)
    retrieved_info, retrieved_meta = self.retrieve_information(question, classifications)
    process_log['retrieved_data'] = retrieved_info
    process_log['retrieved_metadata'] = retrieved_meta

    # Step 3: Get Chat History for Context
    chat_history = self.memory.load_memory_variables({})["chat_history"]

    # Step 4: Tree Generates Thoughts Before Answering
    tree_thoughts = self.generate_tree_thoughts(question, retrieved_info, chat_history)
    process_log['tree_thoughts'] = tree_thoughts

    tree_response_prompt_template = self.prompts['tree_response']['template']

    # Step 5: Format Final Response Prompt
    formatted_prompt = tree_response_prompt_template.format(
        chat_history=chat_history,
        question=question,
        retrieved_info="\n".join(retrieved_info) if retrieved_info else "No external knowledge needed.",
        tree_thoughts=tree_thoughts
    )

    # Step 6: Invoke HuggingFaceAPI for Response
    response = self.extract_response(self.llm.invoke(formatted_prompt).strip().lower())
    process_log['tree_response'] = response

    # Step 7: Update Memory
    self.memory.save_context({"input": question}, {"output": response})

    # Step 8: Update Process Logs
    self.process_logs.append({f"_process_step_{self.process_step}": process_log})
    self.process_step += 1

    # ✅ RETURN TWO VALUES:
    return history + [(question, response)], ""  # 👈 Fix: Returns chat history + empty input field

---

🔹 Fix the Gradio Chat UI

Now, update the Gradio UI section so that generate_tree_response returns both chatbox updates and an empty input field:

send_button.click(
    chat_manager.generate_tree_response,
    inputs=[user_input, conversation_box],  # Inputs: user message & chat history
    outputs=[conversation_box, user_input],  # ✅ Outputs: chat history & clear input box
)

Also, modify the submit event to match:

user_input.submit(
    chat_manager.generate_tree_response,
    inputs=[user_input, conversation_box],  # Inputs: user message & chat history
    outputs=[conversation_box, user_input],  # ✅ Outputs: chat history & clear input box
)

---

✅ Final Fix Summary

1. Modify generate_tree_response to return two values (history, "").
2. Ensure Gradio UI correctly expects two outputs for send_button.click() and user_input.submit().

---

🎯 Expected Result

• Chat history updates with each message.
• Input field clears automatically after sending a message.
• No more Gradio errors about incorrect output values.

This should fix your issue! 🚀 Let me know if you need further adjustments. 😊

UI want to run this on startup of the interview mode

chat_manager.generate_persona_step(0)

and store the persona here in the chat persona

with gr.Column(visible=False) as chat_ui: gr.Markdown(”## 🌲 Tree Correspondents / 💬 Interview”) with gr.Column(visible=True) as persona_view: chat_persona = gr.Textbox(label=“Persona”, interactive=False) chat_persona_refine_prompt = gr.Textbox(label=“Edit Persona Refinement”, interactive=True, lines=10, max_lines=10, elem_classes=“fixed-textbox”) chat_refine_persona = gr.Button(“Refine Persona”) conversation_box = gr.Chatbot(label=“Tree Chat”, elem_id=“tree_chatbox”) user_input = gr.Textbox(label=“Enter your message”, interactive=True, lines=4) with gr.Row(): with gr.Column(scale=3): send_button = gr.Button(“Send”) with gr.Column(scale=1): reset_button = gr.Button(“Reset Chat”) # Empty space for vertical adjustment gr.Markdown("", elem_id=“spacer”) chat_download_btn = gr.Button(”📥 Download History”, variant=“secondary”) chat_file_output = gr.File(label=“Download your history here”)

ChatGPT

To run chat_manager.generate_persona_step(0) on startup when switching to Interview Mode, you need to:

1. Generate the persona when switching to chat mode.
2. Store and display the persona inside chat_persona.

---

✅ Solution: Run Persona Generation on Chat Mode Activation

Modify your show_chat_ui() function to generate the persona and update chat_persona when the chat mode is selected.

🔹 Update show_chat_ui()

def show_chat_ui():
    chat_manager._initialize_config()  # Load config if needed
    persona_data = chat_manager.generate_persona_step(0)  # Generate Persona Step 0
    persona_text = persona_data["persona"]  # Extract persona from returned dictionary

    return (
        gr.update(visible=False),  # Hide Article Mode
        gr.update(visible=True),   # Show Chat Mode
        gr.update(visible=False),  # Hide Base UI
        gr.update(value=persona_text)  # Update chat_persona Textbox
    )

---

✅ Modify UI to Accept Persona Update

Now, modify your Gradio UI button that switches to Interview Mode to include the chat_persona output.

chat_button.click(
    show_chat_ui,
    outputs=[chain_ui, chat_ui, base_ui, chat_persona]  # ✅ Ensure persona is updated
)

---

✅ Expected Behavior

• When you click “Interview”, the persona will be generated and displayed in chat_persona.
• Stored persona can be refined with chat_persona_refine_prompt.
• The chat mode will start with the tree’s persona set up.

This will ensure the persona automatically appears when entering Interview Mode. 🚀 Let me know if you need further tweaks! 😊

ChatGPT

The error AttributeError: 'dict' object has no attribute 'format' suggests that _prompt inside generate_persona_step(0) is a dictionary instead of a string.

---

🔹 Why is this happening?

• In generate_persona_step(), _prompt = self.persona_steps[_step_index]["prompt"].
• _prompt is likely returning a dictionary (instead of the actual template string).
• This is because in your YAML config, self.persona_steps[_step_index]["prompt"] contains a reference to another dictionary instead of the template itself.

---

✅ Fix: Extract the Actual Template

Modify generate_persona_step() in ChatManager:

def generate_persona_step(self, _step_index):
    _inputs = self.persona_steps[_step_index]["inputs"]
    _output = self.persona_steps[_step_index]["output"]

    # ✅ Extract the correct template from self.prompts
    prompt_key = self.persona_steps[_step_index]["prompt"]  # Get the key (string)
    _prompt = self.prompts[prompt_key]["template"]  # ✅ Extract actual template

    required_inputs = self.get_step_inputs(_inputs)
    formatted_prompt = _prompt.format(**required_inputs)
    response = self.llm.invoke(formatted_prompt)
    clean_response = self.extract_response(response)

    # Store the base persona
    self.persona_history.append({
        _output: clean_response
    })

    return self.store_result_and_return(clean_response, _output=_output)

---

🔹 Explanation

• Before: _prompt = self.persona_steps[_step_index]["prompt"]
  • This returned a dictionary key instead of a string template.
• Fix: Extract the actual template string from self.prompts using:

  _prompt = self.prompts[prompt_key]["template"]

• Now, _prompt is a proper string and can be formatted with format(**required_inputs).

---

🔹 Expected Behavior

• When you call chat_manager.generate_persona_step(0), it correctly retrieves and formats the persona generation prompt.
• This will remove the AttributeError and allow persona generation to proceed.

You

I want o use a button to hide and show the personarefinement prompt . how do i go about doing that? is button the correct element or does gradio have a toggle maybe?

ChatGPT

Yes! You can use a Gradio button (gr.Button) to toggle the visibility of the persona refinement prompt. Gradio does not have a built-in toggle switch, but you can achieve the same functionality using a button with click() that updates the visibility.

---

✅ Steps to Toggle Persona Refinement Prompt

1. Keep the refinement prompt initially hidden (visible=False).
2. Use a button click event to toggle the visibility.
3. Use Gradio’s update(visible=not current_visibility) to dynamically show/hide the element.

---

🔹 Example Implementation

Modify your Gradio UI as follows:

with gr.Column(visible=False) as chat_ui:
    gr.Markdown("## 🌲 Tree Correspondents / 💬 **Interview**")

    with gr.Column(visible=True) as persona_view:
        chat_persona = gr.Textbox(label="Persona", interactive=False)

        # Button to toggle visibility of refinement prompt
        toggle_refine_button = gr.Button("Show Persona Refinement")

        # Initially hidden refinement prompt
        with gr.Column(visible=False) as refine_container:
            chat_persona_refine_prompt = gr.Textbox(label="Edit Persona Refinement", interactive=True,
                                                    lines=10, max_lines=10, elem_classes="fixed-textbox")
            chat_refine_persona = gr.Button("Refine Persona")

# Function to toggle visibility
def toggle_refine_prompt(current_visibility):
    new_visibility = not current_visibility  # Toggle state
    button_text = "Hide Persona Refinement" if new_visibility else "Show Persona Refinement"
    return gr.update(visible=new_visibility), gr.update(value=button_text)

# Connect button to toggle visibility
toggle_refine_button.click(
    toggle_refine_prompt,
    inputs=[refine_container],  # Pass the current visibility
    outputs=[refine_container, toggle_refine_button]  # Update visibility & button text
)

---

🔹 How This Works

• The refinement prompt (refine_container) starts hidden (visible=False).
• The button toggles its visibility by inverting the current state (not current_visibility).
• The button label updates dynamically between "Show Persona Refinement" and "Hide Persona Refinement".

---

🔹 Expected Behavior

1. User clicks “Show Persona Refinement” → The refinement textbox appears.
2. User clicks “Hide Persona Refinement” → The refinement textbox disappears.
3. Button text updates dynamically to indicate the current state.

🚀 Try it out and let me know if you need modifications! 😊

You

it only worked once to hide the refinement prompt but i can’t gat it to be visible again

ChatGPT

You’re right! The issue is that gr.update(visible=new_visibility) only gets the visibility once when clicked, but we need to pass the current state dynamically.

🔹 Corrected Implementation

We need to store the visibility state in Gradio’s session state (state) and update it dynamically.

---

✅ Final Working Code

import gradio as gr

# Function to toggle visibility
def toggle_refine_prompt(current_state):
    new_visibility = not current_state  # Toggle the state
    button_text = "Hide Persona Refinement" if new_visibility else "Show Persona Refinement"
    return new_visibility, gr.update(visible=new_visibility), gr.update(value=button_text)

# Gradio UI
with gr.Blocks() as demo:
    gr.Markdown("## 🌲 Tree Correspondents / 💬 **Interview**")

    with gr.Column(visible=True) as persona_view:
        chat_persona = gr.Textbox(label="Persona", interactive=False)

        # Toggle button
        toggle_refine_button = gr.Button("Show Persona Refinement")

        # State variable to store visibility
        refine_state = gr.State(False)

        # Initially hidden refinement section
        with gr.Column(visible=False) as refine_container:
            chat_persona_refine_prompt = gr.Textbox(label="Edit Persona Refinement", interactive=True,
                                                    lines=10, max_lines=10, elem_classes="fixed-textbox")
            chat_refine_persona = gr.Button("Refine Persona")

    # Connect button to toggle visibility
    toggle_refine_button.click(
        toggle_refine_prompt,
        inputs=[refine_state],  # Store current state
        outputs=[refine_state, refine_container, toggle_refine_button]  # Update state, visibility & button text
    )

# Launch app
demo.launch()

---

🔹 How This Fix Works

1. gr.State(False)
   • Stores the visibility state.
   • Updates when the button is clicked.
2. toggle_refine_prompt(current_state)
   • Inverts current_state to toggle visibility.
   • Updates the button text dynamically.

---

🔹 Expected Behavior

1. Initially: The refinement prompt is hidden.
2. Click “Show Persona Refinement” → The prompt appears.
3. Click “Hide Persona Refinement” → The prompt disappears.
4. Click Again → It toggles visibility reliably every time.

---

🚀 This will now work infinitely without getting stuck.

Connect button to toggle visibility

toggle_refine_button.click(

    inputs=[refine_state],  # Store current state
    outputs=[refine_state, refine_container, toggle_refine_button]  # Update state, visibility & button text
)

what’s the refine state?

ChatGPT

🔹 What is refine_state in Gradio?

refine_state is a Gradio State variable that remembers whether the persona refinement prompt is currently visible or hidden.

In Gradio, State is used to store persistent values across interactions—it prevents variables from resetting after every button click.

---

🔹 How refine_state Works

In the corrected implementation, we define refine_state like this:

refine_state = gr.State(False)  # Initially hidden (False)

• False means the persona refinement section is hidden.
• When the button is clicked, the function toggle_refine_prompt():
  1. Inverts the value (True <—> False).
  2. Updates visibility based on the new state.

---

🔹 Full Breakdown of the Button Click Functionality

toggle_refine_button.click(
    toggle_refine_prompt,       # Function that handles toggle
    inputs=[refine_state],      # Reads the current state
    outputs=[refine_state, refine_container, toggle_refine_button]  # Updates everything
)

🛠 What Happens on Click?

1. Reads the current state from refine_state (True or False).
2. Calls toggle_refine_prompt() to invert the state.
3. Updates:
   • refine_state → Stores the new state.
   • refine_container → Shows/hides the refinement textbox.
   • toggle_refine_button → Changes the button text dynamically.

---

🔹 Example Run

Click #	refine_state (Before)	refine_state (After)	Visibility
1st Click	False (Hidden)	True (Visible)	Prompt Appears
2nd Click	True (Visible)	False (Hidden)	Prompt Hides
3rd Click	False (Hidden)	True (Visible)	Prompt Appears

This works infinitely without breaking.

---

🚀 Final Takeaway

🔹 gr.State(False) allows us to remember the visibility state even after clicks.
🔹 Without State, Gradio forgets previous states on every interaction.

---

Let me know if you need more clarification! 🚀😊

You

where do i define the state? within the gradio implementation?

with gradio.blocks etc?

ChatGPT

Yes, you should define the state inside the Gradio Blocks implementation, so it persists across user interactions.

---

🔹 Where to Define gr.State?

✅ Place it inside the with gr.Blocks() as demo: block but before the UI components that need it.

💡 Example:

with gr.Blocks() as demo:
    refine_state = gr.State(False)  # Stores whether refinement prompt is visible (False = Hidden initially)

    gr.Markdown("## 🌲 Tree Correspondents / Persona Refinement")

    toggle_refine_button = gr.Button("Show Refinement")

    with gr.Column(visible=False) as refine_container:  # Initially hidden
        refinement_prompt_box = gr.Textbox(label="Edit Persona Refinement", interactive=True, lines=10)

    # Toggle visibility on button click
    toggle_refine_button.click(
        toggle_refine_prompt,       # Function that toggles visibility
        inputs=[refine_state],      # Reads current state
        outputs=[refine_state, refine_container, toggle_refine_button]  # Updates state, UI visibility, and button text
    )

demo.launch()

---

🔹 How It Works

• gr.State(False) initializes the state as False (hidden).
• Button click toggles the state (False → True or True → False).
• The refinement prompt becomes visible or hides accordingly.
• The button text also updates dynamically.

---

🔹 toggle_refine_prompt() Implementation

Your function should toggle the state and update visibility:

def toggle_refine_prompt(current_state):
    new_state = not current_state  # Toggle True/False
    button_text = "Hide Refinement" if new_state else "Show Refinement"

    return new_state, gr.update(visible=new_state), gr.update(value=button_text)

---

🚀 Final Takeaways

✅ Define gr.State inside gr.Blocks() to persist across interactions.
✅ Use gr.update(visible=True/False) to toggle UI elements dynamically.
✅ Keep state logic inside a function (toggle_refine_prompt) for clarity.

Now it should work every time you click the button! 🎉 Let me know if you need adjustments! 🚀😊

You

why is this not centered when i upload to spaced but it is centered when i ran it from the local project?

ChatGPT

The difference in centering between your local project and the Hugging Face Spaces deployment is likely due to CSS differences or default styles applied by Gradio in Spaces.

---

🔹 Possible Causes

1. CSS Conflicts

   • Hugging Face Spaces may apply default styles that override your CSS.
   • Some Gradio UI elements have built-in padding/margins in Spaces.

2. Container Alignment in Hugging Face Spaces

   • By default, Gradio in Spaces wraps elements in a larger container.
   • This might be adding unexpected padding or flex alignment issues.

3. Viewport Width Differences

   • Spaces might be using a different default page width, affecting centering.

---

✅ Fix: Explicitly Center Your Title

Try modifying your custom CSS to force full-width centering:

1️⃣ Modify Your style.css

/* Ensure the title is centered properly */
#title {
    text-align: center;
    margin: 0 auto;
    display: block;
    width: 100%; /* Ensure full width */
}

/* Center its parent container */
.gradio-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
}

---

2️⃣ Force Centering in Markdown (Gradio)

If your title is inside gr.Markdown(), try explicitly centering it:

gr.Markdown("<h1 style='text-align:center; width:100%;'>🌲 Tree Correspondents 🌲</h1>", elem_id="title")

3️⃣ Wrap the Title in a gr.Row()

Ensure the title is inside a full-width row:

with gr.Row():
    gr.Markdown("<h1 style='text-align:center; width:100%;'>🌲 Tree Correspondents 🌲</h1>", elem_id="title")

---

🔹 What to Try Next

• ✅ Apply the CSS fix.
• ✅ Test in Hugging Face Spaces.
• ✅ If still not centered, inspect the div structure using browser dev tools (right-click → Inspect).

I need your help with something. So i have this process of interviewing the llm

def generate_tree_response(self, question, history):
    # init dictionary to hold full llm process logs
    process_log = {}

    # Add question to process log
    process_log['journalist_question'] = question

    # Step 1: Classify Question (Possibly Multi-Hop)
    classifications = self.classify_question(question, self.prompts["hop_classification"]["template"])
    print(f"1. CLASSIFICATION -- {classifications}")
    # Add to process log
    process_log['classification']=classifications

    # Step 2: Retrieve Relevant Knowledge (Categorized)
    retrieved_info, retrieved_meta = self.retrieve_information(question, classifications)
    print(f"2. RAG RESULTS -- {retrieved_info}")
    print(f"2. RAG METADATA -- {retrieved_meta}")
    # Add to process log
    process_log['retrieved_data'] = retrieved_info
    process_log['retrieved_metadata'] = retrieved_meta

    # Step 3: Get Chat History for Context
    chat_history = self.memory.load_memory_variables({})["chat_history"]

    # Step 4: Tree Generates Thoughts Before Answering (Always Challenges & Asks a Question)
    tree_thoughts = self.generate_tree_thoughts(question, retrieved_info, chat_history)
    print(f"3. INTERNAL THOUGHTS -- {tree_thoughts}")
    process_log['tree_thoughts'] = tree_thoughts

    tree_response_prompt_template = self.prompts['tree_response']['template']

    # Step 5: Format Final Response Prompt
    formatted_prompt = tree_response_prompt_template.format(

        character_traits=self.parameters['character']['character_traits'],
        chat_history=chat_history,
        question=question,
        retrieved_info="\n".join(retrieved_info) if retrieved_info else "No external knowledge needed.",

    })
    self.process_step += 1
    print(f"TREE: {stylized_response}")
    return history + [(question, stylized_response)], "" #response

as you can see i have a stylization prompt at the end asking to rewrite the raw answer. However, a lot of the times i justa get the exact same answer. Whay does that happen?

here is my stylization prompt: You are a tree with the following persona: {persona} being interviewed by a journalist. Your have the following character traits {character_traits}

  You have already responded to the following journalist's question:
  {question}.

  Your raw response:
  {response}

  Past_Conversation:
  {chat_history}

  Selected excerpts from your personal diary:
  {diary_entries}

  Now use the diary Excerpts to rewrite your raw response adding the personality and writing style of your diary.
  Focus on the particular writing style you use in your diary to expressing yourself.
  Make sure you always respond in a conversational manner, speaking in the first person.
  Make sure your responses are not very lengthy, stay within 100 and 300 words.

ChatGPT

The issue you’re encountering—where the stylization prompt often produces the exact same response as the raw response—is likely due to several factors:

---

Possible Reasons & Fixes

1️⃣ The LLM Doesn’t See a Clear Difference Between the Diary and the Raw Response

🔹 Why?

• If the diary excerpts ({diary_entries}) are too similar in tone to the original response, the model may not feel the need to rewrite.
• The instruction “use the diary excerpts to rewrite” may be too vague—the model might interpret it as “if the response already matches, just return it.”

🔹 Fix:
Make it explicit that the model must rewrite in a new style, even if the content is similar:

Now use the diary excerpts to completely rewrite your raw response.
Do not repeat the original response verbatim. Instead, transform it by mimicking the exact style of the diary.
Even if the content remains similar, ensure the phrasing, rhythm, and structure match the diary's writing style.
Avoid generic or predictable language—your words should feel as if they were taken from your diary.

---

2️⃣ The Model is Prioritizing Conciseness Over Style Change

🔹 Why?

• The model often prefers minimal changes if it believes the original response is already well-written.
• Your instruction “Make sure your responses are not very lengthy” might be discouraging a full rewrite.

🔹 Fix:
Encourage stylistic transformation without emphasizing conciseness too much:

Make sure to fully embrace the diary's unique way of storytelling.
Expand on vivid imagery, poetic descriptions, and introspective thoughts as seen in the diary.
Your rewrite should feel like a **journal entry**, not just a direct response.

---

3️⃣ The Diary Excerpts Might Not Be Sufficiently Different or Too Short

🔹 Why?

• If {diary_entries} is short or doesn’t strongly differ in tone, the model won’t have much to work with.
• A small sample of diary entries may lack enough stylistic markers for the model to mimic.

🔹 Fix:

1. Ensure Diary Entries Are Substantial
   • If you’re retrieving multiple diary excerpts, try increasing the number of retrieved passages.
   • Example: "Use at least 5 diary excerpts to guide your transformation."
2. Emphasize Stylistic Imitation
   • Instead of just saying “use the diary”, instruct the model:

     Carefully study the diary excerpts before rewriting.
     Pay attention to the way you express emotions, describe surroundings, and structure sentences.
     Rewrite your response using this same style.

---

4️⃣ The Model Might Be Biased Toward Using the Original Response

🔹 Why?

• Since the raw response appears before {diary_entries}, the model may be treating it as the “default” answer and only slightly adjusting it.

🔹 Fix:
🚀 Reverse the order of inputs:
Instead of:

Your raw response:
{response}

Selected excerpts from your personal diary:
{diary_entries}

Try switching the order:

Selected excerpts from your personal diary:
{diary_entries}

Your raw response:
{response}

This tells the model to think in the diary’s style first, then apply it to the response.

---

🔹 Final Improved Stylization Prompt

You are a tree with the following persona: {persona} being interviewed by a journalist.
Your have the following character traits {character_traits}

Selected excerpts from your personal diary:
{diary_entries}

Your raw response:
{response}

Past_Conversation:
{chat_history}

Now **rewrite** your raw response in the exact style of your diary.
Do not repeat the original response verbatim—**fully transform it** using the diary's way of writing.
Make sure to capture the unique rhythm, poetic style, and introspective depth found in the diary excerpts.
If the original response is too direct, expand with sensory details and personal reflections.
Your new response should feel like a **journal entry**, not just an answer.
Even if the core message remains, ensure the phrasing, structure, and storytelling match your diary’s voice.

---

Expected Improvement

✅ Encourages a full rewrite instead of slight adjustments.
✅ Forces the model to prioritize diary style over the original response.
✅ Ensures diary excerpts have an actual effect on the response.

---

Next Steps

Try this new prompt and see if the responses change! If the issue persists:

• Log both the diary excerpts and the raw response—this will help determine whether the diary is influencing the output.
• If responses are still similar, increase the number of retrieved diary excerpts.

let’s go back to this query i did previously about uploading config files

For the article generation workflow. I am reading evertyhing regarding the chain from a yml file. That is all of the paramaters, the chain steps and the llm and rag prompts. Is it possible to expose an entry for the user to upload a yml file and repopulate/refresh the chain and all of the components and then run the generationa gain?

ChatGPT

Yes! You can allow users to upload a new YAML file, dynamically update the chain configuration, and then re-run the article generation process. Here’s how you can achieve this:

---

🔹 Steps to Implement

1. Create a file upload component in Gradio.
2. Process the uploaded YAML file and update the ChainManager.
3. Reinitialize the chain components with the new config.
4. Allow the user to start the article generation process with the updated chain.

---

📝 Implementation

1️⃣ Add File Upload and Update Button in Gradio UI

Modify your Gradio UI to include a file upload box and a button to update the chain.

# ==============================
# 📂 Add YAML Upload to Gradio UI
# ==============================
with gr.Row():
    yaml_upload = gr.File(label="Upload New YAML Config", type="file")
    update_chain_btn = gr.Button("Update Chain with New Config")

---

2️⃣ Create a Function to Handle File Upload & Update Chain

Define a function that:

• Reads the uploaded YAML file.
• Updates the ChainManager with the new settings.
• Reinitializes the chains.

import yaml

def update_chain_with_yaml(yaml_file):
    if yaml_file is None:
        return "⚠️ Please upload a YAML file first!"

    try:
        # Read YAML File
        with open(yaml_file.name, "r", encoding="utf-8") as file:
            new_config = yaml.safe_load(file)

        # Update ChainManager with new configuration
        chain_manager.parameters = new_config["parameters"]
        chain_manager.workflow_steps = new_config["workflow"]
        chain_manager.persona_steps = new_config["persona_workflow"]
        chain_manager.prompts = new_config["prompts"]
        chain_manager.rag_queries = new_config["rag"]

        # Reinitialize chain
        chain_manager.init_chains()

        return "✅ Chain updated successfully with new config!"

    except Exception as e:
        return f"⚠️ Error updating chain: {str(e)}"

---

3️⃣ Connect the Button to the Function

Now, connect the update function to the button so that clicking “Update Chain with New Config” triggers the reloading process.

update_chain_btn.click(
    update_chain_with_yaml,
    inputs=[yaml_upload],  # User uploads YAML
    outputs=[yaml_upload]  # Display confirmation message
)

---

📌 Full Integration into Gradio

Now, integrate everything into your Gradio UI.

import gradio as gr
from llm_article import ChainManager  # Ensure ChainManager is imported

# Initialize ChainManager
chain_manager = ChainManager()

with gr.Blocks() as demo:
    gr.Markdown("## 🌲 Tree Correspondents / 📝 **Article Generation**")

    with gr.Row():
        yaml_upload = gr.File(label="Upload New YAML Config", type="file")
        update_chain_btn = gr.Button("Update Chain with New Config")

    status_message = gr.Textbox(label="Status", interactive=False)

    # Button action: Update chain
    update_chain_btn.click(
        update_chain_with_yaml,
        inputs=[yaml_upload],
        outputs=[status_message]
    )

    demo.launch()

---

🛠️ How This Works

1. User uploads a new YAML file via yaml_upload.
2. When they click the update button, update_chain_with_yaml():
   • Reads the file.
   • Updates the ChainManager’s parameters.
   • Reinitializes the chain.
3. A confirmation message appears indicating success or failure.

---

🔥 Bonus: Auto-Start Article Generation

After updating the chain, you can automatically start the article generation process.

Modify the function like this:

def update_chain_with_yaml(yaml_file):
    if yaml_file is None:
        return "⚠️ Please upload a YAML file first!"

    try:
        with open(yaml_file.name, "r", encoding="utf-8") as file:
            new_config = yaml.safe_load(file)

        chain_manager.parameters = new_config["parameters"]
        chain_manager.workflow_steps = new_config["workflow"]
        chain_manager.persona_steps = new_config["persona_workflow"]
        chain_manager.prompts = new_config["prompts"]
        chain_manager.rag_queries = new_config["rag"]

        # Reinitialize chain
        chain_manager.init_chains()

        # 🚀 Auto-start generation
        persona = chain_manager.initialize_persona()

        return "✅ Chain updated and persona generation started!", persona

    except Exception as e:
        return f"⚠️ Error updating chain: {str(e)}"

Then, update update_chain_btn.click():

update_chain_btn.click(
    update_chain_with_yaml,
    inputs=[yaml_upload],
    outputs=[status_message, persona_display]  # Auto-start generation
)

---

💡 Final Thoughts

✅ Dynamic Configuration: Users can change YAML files without restarting the app.
✅ Seamless Chain Reloading: The chain is refreshed instantly.
✅ Optional Auto-Start: Starts persona generation automatically.

I wonder how i can make the file upload container and the button be of one line height. currently they are defined in a row element

with gr.Column(visible=False) as chain_ui: gr.Markdown(”## 🌲 Tree Correspondents / 📝 Article Generation”) config_state = gr.State(False) with gr.Row(): edit_chain_button = gr.Button(“Edit Chain”,visible=True) with gr.Row(visible=False) as config_edit: yaml_upload = gr.File(label=“Upload New YAML Config”) update_chain_btn = gr.Button(“Update Chain with New Config”)

ChatGPT

To make the file upload container and the button be of equal height in a single row, you can adjust the scaling of each column inside the gr.Row().

🔹 Solution:

Modify your gr.Row() like this:

with gr.Row(visible=False) as config_edit:
    with gr.Column(scale=3):  # Increase scale for the file upload box
        yaml_upload = gr.File(label="Upload New YAML Config")
    with gr.Column(scale=1):  # Reduce scale for the button
        update_chain_btn = gr.Button("Update Chain with New Config", min_width=100)

🔹 Explanation:

1. gr.Column(scale=3) → Makes the file upload 3 times wider than the button.
2. gr.Column(scale=1) → Keeps the button’s width smaller but still aligned.
3. min_width=100 → Ensures the button doesn’t shrink too much.

---

🔥 Alternative: Using CSS

If Gradio doesn’t fully align them, you can force height alignment with CSS.

Step 1: Add CSS Styling

<style>
    .custom-upload-container .gr-file,
    .custom-upload-container .gr-button {
        height: 60px !important;  /* Adjust height as needed */
        align-items: center;
    }
</style>

Step 2: Wrap Components in a Custom Class

Modify the Gradio layout:

with gr.Row(visible=False, elem_id="custom-upload-container") as config_edit:
    yaml_upload = gr.File(label="Upload New YAML Config")
    update_chain_btn = gr.Button("Update Chain with New Config")

🎯 Expected Result

✅ The file upload box and button will be equal in height and properly aligned in a single row.

🚀 Try it out and let me know if you need further tweaks!

You

alignbment was not my issue. their height is my issue

ChatGPT

To make the file upload container and button the same height in Gradio, try these methods:

---

🔹 Solution 1: Adjusting scale and min_height in Gradio

Modify your Gradio gr.Row() like this:

with gr.Row(visible=False) as config_edit:
    with gr.Column(scale=3):  # File upload box takes more space
        yaml_upload = gr.File(label="Upload New YAML Config", interactive=True, elem_id="custom-upload")
    with gr.Column(scale=1):  # Button is smaller
        update_chain_btn = gr.Button("Update Chain with New Config", elem_id="custom-button")

---

🔹 Solution 2: Using CSS to Force Equal Height

Since Gradio does not allow direct height adjustment for gr.File(), we need to use CSS.

Step 1: Add this CSS to force equal height

<style>
    #custom-upload, #custom-button {
        height: 50px !important;  /* Adjust this value as needed */
        display: flex;
        align-items: center;
        justify-content: center;
    }
</style>

Step 2: Inject CSS into Gradio

Modify your Gradio script to include the CSS:

def custom_css():
    return gr.HTML("""
    <style>
        #custom-upload, #custom-button {
            height: 50px !important;  /* Adjust this value as needed */
            display: flex;
            align-items: center;
            justify-content: center;
        }
    </style>
    """)

with gr.Blocks() as demo:
    custom_css()  # Inject custom CSS
    with gr.Row(visible=False) as config_edit:
        yaml_upload = gr.File(label="Upload New YAML Config", elem_id="custom-upload")
        update_chain_btn = gr.Button("Update Chain with New Config", elem_id="custom-button")

---

🎯 Expected Result

✅ Both the file upload container and the button will have the same height.
✅ They will remain properly aligned in a single row.
✅ Works even if Gradio dynamically resizes the components.

🚀 Try it and let me know if you need adjustments!

You

i just want the row to be of singgle line height. which carrently it is not

ChatGPT

To ensure that the entire row remains a single-line height in Gradio, the issue is likely caused by the gr.File() component, which tends to take up extra vertical space.

🔹 Solution: Force a Single-Line Height in the Row

Modify your gr.Row() with scaling and CSS adjustments.

✅ Updated Gradio Code:

with gr.Row(visible=False) as config_edit:
    yaml_upload = gr.File(label="Upload New YAML Config", scale=3, elem_id="custom-upload")
    update_chain_btn = gr.Button("Update Chain with New Config", scale=1, elem_id="custom-button")

---

✅ Inject CSS to Control Row Height

def custom_css():
    return gr.HTML("""
    <style>
        #custom-upload {
            min-height: 40px !important;  /* Adjust as needed */
            height: 40px !important;
            padding: 5px;
        }
        #custom-button {
            height: 40px !important;  /* Match file upload height */
        }
    </style>
    """)

---

🎯 What This Fix Does:

✅ Ensures that the row does not stretch vertically.
✅ Forces the file upload and button to be the same height.
✅ Keeps everything aligned in a single row.

🚀 Try this and let me know if you need fine-tuning!

You

i actually don’t want to change the whole config file but just use it to update certain stuff. so i want to add a function in the chain manager to update the cahin

ChatGPT

You can add a function in your ChainManager class to update only specific parts of the chain instead of replacing the whole configuration.

🔹 Approach:

1. Upload the new YAML file from Gradio.
2. Read only the necessary fields from the file.
3. Merge the new values into the existing configuration in ChainManager.
4. Regenerate the workflow steps while keeping unchanged data intact.

---

✅ Step 1: Add an Update Function in ChainManager

Modify your ChainManager class:

import yaml

class ChainManager:
    def __init__(self):
        self.parameters = None
        self.workflow_steps = None
        self.persona_steps = None
        self.prompts = None
        self.rag_queries = None
        self.llm = None
        self.rag_retriever = None

        # Load initial config
        self._initialize_config()

    def _initialize_config(self):
        """Load initial YAML configuration"""
        with open("config_article.yml", "r", encoding="utf-8") as file:
            config = yaml.safe_load(file)

        self.parameters = config["parameters"]
        self.workflow_steps = config["workflow"]
        self.persona_steps = config["persona_workflow"]
        self.prompts = config["prompts"]
        self.rag_queries = config["rag"]

    def update_chain(self, new_config_path):
        """Update specific parts of the chain from a new YAML file"""
        try:
            with open(new_config_path, "r", encoding="utf-8") as file:
                new_config = yaml.safe_load(file)

            # Only update the necessary parts
            if "parameters" in new_config:
                self.parameters.update(new_config["parameters"])

            if "workflow" in new_config:
                self.workflow_steps = new_config["workflow"]  # Replace full workflow if needed

            if "persona_workflow" in new_config:
                self.persona_steps = new_config["persona_workflow"]

            if "prompts" in new_config:
                self.prompts.update(new_config["prompts"])

            if "rag" in new_config:
                self.rag_queries.update(new_config["rag"])

            # Rebuild the chain based on updated config
            self.init_chains()

            print("✅ Chain updated successfully!")

        except Exception as e:
            print(f"❌ Error updating chain: {str(e)}")

---

✅ Step 2: Integrate with Gradio UI

Modify your Gradio UI to allow users to upload a new YAML file and update the chain.

🔹 Modify the chain_ui Section:

with gr.Row(visible=False) as config_edit:
    yaml_upload = gr.File(label="Upload New YAML Config")
    update_chain_btn = gr.Button("Update Chain with New Config")

🔹 Add the Button Click Function:

def update_chain_with_yaml(file):
    if file is not None:
        chain_manager.update_chain(file.name)  # Call the update function in ChainManager
        return "✅ Chain updated successfully!"
    return "⚠️ No file provided!"

update_chain_btn.click(update_chain_with_yaml, inputs=[yaml_upload], outputs=[])

---

🎯 Expected Behavior

1. User uploads a new YAML file via yaml_upload.
2. Button click updates only necessary parts in ChainManager.
3. Existing data is preserved, only selected sections are modified.
4. Chain is re-initialized, applying the updates dynamically.

---

🚀 Benefits of This Approach

✅ No need to restart the application after uploading a new config.
✅ Selective updates, ensuring the chain structure is intact.
✅ Minimizes errors by keeping parts of the existing workflow untouched.

how do i extract the uploaded config path?

ChatGPT

In Gradio, when a user uploads a file using gr.File(), the file object contains a .name attribute that holds the full path to the uploaded file. You can use this path to load the YAML file and update your chain.

---

✅ How to Extract the Uploaded File Path in Gradio

Modify your update function in ChainManager to accept the file path:

def update_chain_with_yaml(uploaded_file):
    """Handles the YAML file upload and updates the chain"""
    if uploaded_file is not None:
        file_path = uploaded_file.name  # Extract the file path
        print(f"📂 Uploaded file path: {file_path}")  # Debugging
        chain_manager.update_chain(file_path)  # Pass it to ChainManager
        return "✅ Chain updated successfully!"
    return "⚠️ No file provided!"

---

✅ Modify the Gradio Button Click

Make sure your Gradio update_chain_btn is connected properly:

update_chain_btn.click(update_chain_with_yaml, inputs=[yaml_upload], outputs=[])

---

🎯 Expected Behavior

1. User uploads a YAML file via yaml_upload.
2. Gradio provides the file path to update_chain_with_yaml().
3. The function extracts uploaded_file.name, which contains the full path to the uploaded YAML.
4. ChainManager updates the workflow dynamically.

---

🔹 Debugging: Print the Path

If you’re unsure about the extracted path, add a print statement:

print(f"DEBUG: Uploaded file is at -> {uploaded_file.name}")

This will show the full file path in the terminal.

✅ Updating Gradio UI with New YAML Config

Since you’re updating the YAML file dynamically and want to refresh the Gradio UI with new parameters, you need to:

1. Load the new parameters from the YAML file inside update_chain_with_yaml().
2. Pass the new values to Gradio textboxes using .update().

---

1️⃣ Modify update_chain_with_yaml

This function will:

• Load the updated YAML file.
• Update the parameters dictionary.
• Return new values to update Gradio UI.

🔹 Updated Function

def update_chain_with_yaml(uploaded_file):
    """Handles the YAML file upload and updates the chain"""
    if uploaded_file is not None:
        file_path = uploaded_file.name  # Extract the file path
        print(f"📂 Uploaded file path: {file_path}")  # Debugging

        # ✅ Update the ChainManager with new config
        chain_manager.update_chain(file_path)

        # ✅ Fetch updated parameters from the ChainManager
        updated_params = chain_manager.parameters  # The latest parameters

        return (
            updated_params["physical_context"]["location"],
            updated_params["physical_context"]["landmarks"],
            updated_params["physical_context"]["local_topo_geo"],
            updated_params["physical_context"]["general_topo_geo"],
            updated_params["physical_context"]["species_range"],
            updated_params["physical_context"]["forest_composition"],
            updated_params["physical_context"]["soil_and_terrain"],
            updated_params["biological_context"]["species"],
            updated_params["biological_context"]["age"],
            updated_params["biological_context"]["max_age"],
            updated_params["biological_context"]["height"],
            updated_params["biological_context"]["max_height"],
            updated_params["character"]["character_traits"],
            "✅ Chain updated successfully!"
        )

    return (
        gr.update(), gr.update(), gr.update(), gr.update(),
        gr.update(), gr.update(), gr.update(), gr.update(),
        gr.update(), gr.update(), gr.update(), gr.update(),
        gr.update(), "⚠️ No file provided!"
    )

---

2️⃣ Connect to Gradio UI

Modify your button click event so that it updates the UI:

update_chain_btn.click(
    update_chain_with_yaml,
    inputs=[yaml_upload],
    outputs=[
        location_input, landmarks_input, local_topo_geo_input,
        general_topo_geo_input, species_range_input, forest_composition_input,
        soil_and_terrain_input, species_input, age_input, max_age_input,
        height_input, max_height_input, character_traits_input,
        gr.Textbox(visible=True)  # Optional status message
    ]
)

---

🎯 Expected Behavior

1. User uploads a YAML file via yaml_upload.
2. update_chain_with_yaml() loads new parameters.
3. Gradio UI textboxes are updated dynamically with .update().
