The varying execution times in your script could be due to several factors, such as network latency, processing time variations in the model inference, or possibly the I/O operations (like reading/writing to CSV files). Here are some potential areas to investigate and optimize:

Network Latency:
- Ensure that there are no network issues causing delays in the OSC server communication.
Model Inference Time:
- Model loading and inference times can vary. Preloading the models before starting the server might help.
- Ensure that the models are not being loaded multiple times.
I/O Operations:
- Writing to the CSV file and other I/O operations might cause delays.
- Ensure that file I/O is optimized, perhaps using asynchronous I/O.
Concurrency:
- Make sure that your asynchronous functions are not blocking the event loop.

Let’s refactor and optimize some parts of your script to see if we can improve the performance consistency:

Preload Models

First, preload the models before starting the OSC server.

# Preload models at the beginning
def preload_models():
    offensive_classifier = pipeline("text-classification", model=Config.OFFENSIVE_MODEL)
    context_classifier = pipeline("zero-shot-classification", model=Config.CONTEXT_MODEL)
    return offensive_classifier, context_classifier

Handle OSC Message with Preloaded Models

Pass the preloaded models to the handler to avoid reloading them.

async def handle_osc_message(unity_client: SimpleUDPClient,
                             td_client: SimpleUDPClient,
                             unused_addr,
                             offensive_classifier: Pipeline,
                             context_classifier: Pipeline,
                             sentence):
    start = time.time()
    print("I received message from Unity")
    print(f"Input message: {sentence}")
    response, attribute, new_msg, word_response = await classify_sentence(sentence,
                                                                          offensive_classifier,
                                                                          context_classifier)

    print(f"Received response from classify_sentence: {response}, {attribute}, {new_msg}, {word_response}")

    save_string_to_csv(file_path, f"{sentence} , {attribute}, {word_response}")

    unity_client.send_message("/response", response)

    td_client.send_message(f"/{attribute.primary}", attribute.primary_value)
    td_client.send_message(f"/{attribute.secondary}", attribute.secondary_value)
    td_client.send_message(f"/{attribute.tertiary}", attribute.tertiary_value)
    td_client.send_message(f"/{attribute.quaternary}", attribute.quaternary_value)
    td_client.send_message("/newMessage", new_msg)
    td_client.send_message("/wordResponse", word_response)
    td_client.send_message("/message", f"Message received: '{sentence}'")
    end = time.time()
    td = (end - start) * 10 ** 3
    print(f"The time of execution of above program is : {td}ms")

Async I/O for CSV Writing

Use asynchronous I/O to write to the CSV file to avoid blocking.

import aiofiles

async def save_string_to_csv(file_path, string_to_save):
    # Ensure the directory exists
    os.makedirs(os.path.dirname(file_path), exist_ok=True)

    async with aiofiles.open(file_path, mode='a') as file:
        await file.write(string_to_save + '\n')

Main Function Update

Update the main function to preload models and use the async CSV writer.

def main():
    """
    Main function to set up and run the OSC server.
    """

    args = parse_args()

    unity_client = udp_client.SimpleUDPClient(args.unity_ip, args.unity_port)
    td_client = udp_client.SimpleUDPClient(args.td_ip, args.td_port)

    offensive_classifier, context_classifier = preload_models()

    disp = dispatcher.Dispatcher()
    disp.map("/florence_sentence", lambda unused_addr, *osc_args: asyncio.run(
        handle_osc_message(unity_client, td_client, unused_addr,
                           offensive_classifier, context_classifier,
                           *osc_args)))

    server = osc_server.ThreadingOSCUDPServer((args.local_ip, args.local_port), disp)
    print(f"Serving on {server.server_address}")
    server.serve_forever()

if __name__ == "__main__":
    main()

Running the Updated Script

Run the updated script and observe the execution times. These changes should help reduce the variance in execution time by preloading models and using asynchronous I/O operations.

Additionally, you can profile your script to find the exact bottlenecks. Python’s cProfile module or third-party tools like line_profiler can help you identify slow parts of your code.

Here is the updated script incorporating the suggested changes for preloading models and using asynchronous I/O operations:

This updated script preloads the models and uses asynchronous I/O for CSV file writing, which should help improve and stabilize the execution times.

The error indicates that the aiofiles module is not installed in your Python environment. You can install it using pip. Open a terminal or command prompt and run the following command:

pip install aiofiles

After installing aiofiles, you can rerun your script. If you encounter any further issues or have additional questions, please let me know.

I just reran it. Looking at the results of the previous version compared to the new version, some messages that were previously fast to process are now slower. I need to identify why some messages are processing so much slower.

Previous Version debug text:

New version debug text:

The inconsistencies in execution times, especially with some messages that were previously faster now taking longer, indicate that the changes might have introduced new inefficiencies or exacerbated existing ones. Here are some steps to diagnose and potentially resolve the issue:

Steps to Diagnose:

Profile Execution Time: Profile the execution of different parts of your code to identify bottlenecks. Python’s cProfile module can be helpful for this.
Check Async I/O: Verify that the use of aiofiles for asynchronous I/O is not introducing delays.
Model Inference Time: Ensure that model inference time is consistent and not causing delays.

Updated Script with Profiling and Improvements:

Let’s add profiling to different parts of the script to measure execution times for various functions. This will help identify where the time is being spent.

Explanation:

Profiling with cProfile: Added profiling to the main() function to analyze the entire script’s performance.
Measure Time: Added time measurements in the classify_sentence function to see how long it takes to process sentences.
Asynchronous I/O: Continued to use aiofiles for writing to CSV files asynchronously.

Run this updated script and check the profiling results to identify bottlenecks. The detailed profiling output will help you pinpoint which parts of the code are taking the most time, enabling you to make more targeted optimizations.

Still getting very mixed results, it doesn’t seem to be dependent on the input message at all. You can see that the time to classify and the overall time are almost the same suggesting nothing else is causing a delay. I’ve been monitoring PC performance and it doesn’t seem to be linked to RAM or CPU usage either. See below output:

The execution times show that there are significant inconsistencies that seem independent of the input message. Since the overall time and the classify_sentence time are almost the same, it indicates that the delay is within the classify_sentence function.

Steps to Diagnose Further:

Separate Profiling: Profile different parts within classify_sentence to see which part takes the most time.
Logging: Add more detailed logging to understand where the delays are occurring.
Check External Dependencies: Ensure that external dependencies (e.g., internet access for models) are not causing delays.

Detailed Profiling and Logging within `classify_sentence`:

Here’s an updated script with more granular profiling and logging inside classify_sentence.

Explanation:

Granular Profiling: Added time measurements for each major step inside the classify_sentence function to see where the time is being spent.
Consistent Offline Setup: Ensured that the script runs entirely offline, as per your setup.

Run the script with these changes, and observe the detailed timing logs to identify where the delays are occurring. This should help in pinpointing the exact part of the function that is causing the inconsistencies.

Doesn’t seem like the time taken to extract the word accounts for the longer times. The first few messages always seem to be quite quick though, could it be some sort of caching issue or build up as it runs over time? See below outputs:

Given the pattern observed, it seems that the analyze_sentence function, specifically the pipeline call, might be the primary cause of the inconsistency. This is not uncommon, as the first few calls to a model can benefit from caching, but over time, the performance can degrade due to memory usage or other factors.

Next Steps:

Model Warm-up: Run the model once during initialization to ensure it is loaded into memory.
Memory Management: Ensure that the memory is being managed correctly and there are no memory leaks.
Periodic Restart: Restart the model or clear cache periodically.

Updated Script with Model Warm-up and Improved Memory Management:

Here’s the updated script with an initial warm-up call and memory management improvements:

Key Changes:

Model Warm-up: Added warm-up calls during the model preload to ensure that the models are loaded into memory.
Garbage Collection: Explicitly triggered garbage collection (gc.collect()) at the end of the classify_sentence function to manage memory usage.
Memory Management: Ensured that memory management is handled correctly to avoid any leaks or buildup over time.

Running the Script:

Run the updated script and observe the detailed timing logs and memory management. This should help in identifying if caching or memory buildup issues are causing the delays.

This time, again, the first few messages processed quickly and then all the following took approx 13s. It seems strange that they all take pretty much 13s, it’s a very consistent duration.

See log:

The consistent 13-second delay after the first few messages strongly suggests a resource or configuration issue rather than a problem with the script itself. Here are some further steps to investigate and mitigate this:

Resource Exhaustion: Ensure the system is not running out of resources (CPU, RAM) which can cause such delays.
Batch Processing: Try processing multiple requests in a single batch to see if it helps.
Model Warm-Up: Explicitly warm-up the model on a set of predefined sentences to ensure all necessary components are loaded and cached.
Optimize the Transformer Model: Use optimized transformer models which might perform better in terms of inference speed.
Profile Memory Usage: Check if memory usage is growing over time, indicating a potential memory leak.

Here is a refined version of the script with a warm-up phase and batch processing to improve performance:

import random
import argparse
import asyncio
from typing import Tuple
import aiofiles
import os
import nltk
from transformers import pipeline, Pipeline
from pythonosc import dispatcher, osc_server, udp_client
from pythonosc.udp_client import SimpleUDPClient
import time
import gc

# Use Local NLTK data
nltk.data.path.append('C:/Users/Florence Nightingale/AppData/Roaming/nltk_data')

# Initialize global message counter
new_message = 0

file_path = 'C:/Users/Florence Nightingale/Documents/Florence Nightingale Living Portrait/InputHistory.csv'

class Config:
    """
       Configuration class for default values and settings.

       Attributes:
           LOCAL_IP (str): IP address for the local machine.
           TABLET_IP (str): IP address for the tablet.
           LOCAL_PORT (int): Port for the local machine to listen on.
           TD_PORT (int): Port for the TD (transmitting device).
           TABLE

Given that resource exhaustion and batch processing are not the issues, we should consider the following strategies to pinpoint and potentially solve the problem:

Model Reload: Periodically reload the model to clear any internal state that might be causing delays.
Debug Mode: Add more detailed logging to identify exactly where the delay happens.
Profiling: Use a profiler to understand the time spent in various parts of the code.

Here’s an updated version of the script with detailed logging and model reloading after a certain number of requests. This approach can help to determine if the model’s state is contributing to the delay.

Key Changes:

Detailed Logging: Added more detailed logging to each step to help identify where delays might occur.
Model Reload: Introduced a mechanism to reload the models after a certain number of requests to reset any internal state that might be causing the delays.

Run the updated script and observe the detailed logs to determine if the model reloading helps or if the logs provide additional insights into the delays.
