Problem With Run_society Coroutine In Run_ollama.py

Bug Report: Multiple issues with run_society coroutine in run_ollama.py

Description

The run_ollama.py script has encountered several issues with the run_society coroutine. Initially, the async function run_society was being called without being awaited, resulting in a "coroutine was never awaited" warning. After adding the await keyword, a Playwright error related to using Playwright Sync API inside an async loop was encountered.

Error Messages

Initial error (without await):

.../owl/owl/run_ollama.py:128: RuntimeWarning: coroutine 'run_society' was never awaited
answer, chat_history, token_count = run_society(society)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
Traceback (most recent call last):
File ".../owl/owl/run_ollama.py", line 135, in <module>
asyncio.run(main())
File ".../owl/owl/run_ollama.py", line 128, in main
answer, chat_history, token_count = run_society(society)
TypeError: cannot unpack non-iterable coroutine object

Error after adding await:

Error
It look like you are using Playwright Sync API inside the async loop

Steps to Reproduce

To reproduce the issue, follow these steps:

  1. Run the run_ollama.py script with the original code (without await)
  2. Modify the code to add await before run_society(society) and run again

Environment

The issue was encountered on the following environment:

  • Python version: [Your Python version]
  • OS: macOS
  • Playwright version: [Your Playwright version]

Root Cause

There are two distinct issues:

  1. Coroutine issue: The run_society function in enhanced_role_playing.py is defined as an async function, but it was initially being called synchronously.
  2. Playwright issue: After properly awaiting the function, a Playwright error was encountered. This suggests that the BrowserToolkit is using Playwright's synchronous API within an asynchronous context, which is not supported. Playwright has two distinct APIs (sync and async) that cannot be mixed.

Proposed Fix

The solution requires addressing both issues:

  1. Coroutine issue: Properly await the run_society function.
  2. Playwright issue: Either:
    • Modify the BrowserToolkit to use Playwright's async API consistently when used in async contexts
    • Create a separate synchronous execution path for the entire workflow

A potential approach could be:

# Option 1: If BrowserToolkit can be modified to use async API
async def main():
    society = construct_society(question)
    answer, chat_history, token_count = await run_society(society)
    print(f"\033[94mAnswer: {answer}\033[0m")

# Option 2: If we need to keep the sync API, run in a separate thread
def main():
    society = construct_society(question)
    
    # Run the async function in a new thread to avoid mixing sync/async
    import threading
    result = None
    
    def run_in_thread():
        nonlocal result
        loop = asyncio.new_event_loop()
        asyncio.set_event_loop(loop)
        result = loop.run_until_complete(run_society(society))
        loop.close()
    
    thread = threading.Thread(target=run_in_thread)
    thread.start()
    thread.join()
    
    answer, chat_history, token_count = result
    print(f"\033[94mAnswer: {answer}\033[0m")

Additional Context

This appears to be a common issue when mixing Playwright's sync and async APIs. According to Playwright documentation, you should consistently use either the sync or async API throughout your application, but not mix them.

The BrowserToolkit in the OWL project likely needs to be updated to properly support async execution contexts, or the execution flow needs to be restructured to avoid mixing sync and async code.

Conclusion

The run_society coroutine in run_ollama.py has encountered multiple issues, including a coroutine was never awaited warning and a Playwright error. The proposed fix involves addressing both issues by properly awaiting the run_society function and either modifying the BrowserToolkit to use Playwright's async API or creating a separate synchronous execution path for the entire workflow.

Recommendations

To avoid similar issues in the future, it is recommended to:

  • Always await async functions to avoid coroutine was never awaited warnings
  • Consistently use either the sync or async API throughout your application
  • Update the BrowserToolkit to properly support async execution contexts
  • Restructure the execution flow to avoid mixing sync and async code

Q: What is the issue with the run_society coroutine in run_ollama.py?

A: The issue is that the run_society function is being called without being awaited, resulting in a "coroutine was never awaited" warning. Additionally, after adding the await keyword, a Playwright error related to using Playwright Sync API inside an async loop is encountered.

Q: What is the root cause of the issue?

A: There are two distinct issues:

  1. Coroutine issue: The run_society function in enhanced_role_playing.py is defined as an async function, but it was initially being called synchronously.

Q: How can I fix the coroutine issue?

A: To fix the coroutine issue, you need to properly await the run_society function. This can be done by adding the await keyword before calling the function.

Q: How can I fix the Playwright issue?

A: To fix the Playwright issue, you need to either:

  1. Modify the BrowserToolkit to use Playwright's async API consistently: This involves updating the BrowserToolkit to properly support async execution contexts.
  2. Create a separate synchronous execution path for the entire workflow: This involves restructuring the execution flow to avoid mixing sync and async code.

Q: What are the potential approaches to fix the Playwright issue?

A: There are two potential approaches to fix the Playwright issue:

  1. Option 1: If BrowserToolkit can be modified to use async API: This involves updating the BrowserToolkit to properly support async execution contexts.
  2. Option 2: If we need to keep the sync API, run in a separate thread: This involves restructuring the execution flow to avoid mixing sync and async code.

Q: What are the benefits of using async API in Playwright?

A: Using async API in Playwright provides several benefits, including:

  • Improved performance: Async API allows for concurrent execution of tasks, which can improve performance.
  • Better scalability: Async API makes it easier to scale applications by allowing for concurrent execution of tasks.
  • Easier maintenance: Async API makes it easier to maintain code by reducing the complexity of synchronous code.

Q: What are the best practices for using async API in Playwright?

A: The best practices for using async API in Playwright include:

  • Always await async functions: This ensures that async functions are properly executed and avoids coroutine was never awaited warnings.
  • Consistently use either the sync or async API: This ensures that the application is properly executed and avoids mixing sync and async code.
  • Update the BrowserToolkit to properly support async execution contexts: This ensures that the BrowserToolkit is properly configured to support async execution contexts.

Q: What are the common mistakes to avoid when using async API in Playwright?

A: The common mistakes to avoid when using async API in Playwright include:

  • Mixing sync and async code: This can lead to errors and make the code harder to maintain.
  • Not awaiting async functions: This can lead to coroutine was never awaited warnings and errors.
  • Not updating the BrowserToolkit to properly support async execution contexts: This can lead to errors and make the code harder to maintain.
