Hello, This a reply from our support bot designed to assist you with your Weights & Biases related queries. To reach a human please reply to this message.

It seems like you’re experiencing an issue where your execution gets stuck at wait_for_tstate_lock(). This problem is typically related to threading in Python and might not be directly related to Weights & Biases. However, I can provide some general advice and steps you can take to troubleshoot and potentially resolve this issue:

  1. Check for Deadlocks: The wait_for_tstate_lock() issue often arises due to deadlocks in your code. Ensure that there are no circular dependencies or infinite loops in threads waiting for resources locked by each other.

  2. Review Thread Management: Make sure you are correctly managing the creation and destruction of threads. Too many threads or improperly managed threads can lead to this kind of issue.

  3. Update Dependencies: Ensure that all your dependencies, especially Weights & Biases, are up to date. Sometimes, bugs related to threading are fixed in newer versions of libraries.

  4. Simplify Your Code: Try to simplify your code to the smallest version that still reproduces the issue. This can help identify whether the problem is with Weights & Biases integration or another part of your code.

  5. Use Debugging Tools: Utilize Python’s debugging tools, such as logging or the threading module’s debugging features, to get more insight into what your threads are doing and where they might be getting stuck.

  6. Check Weights & Biases Initialization: Ensure that wandb.init() is called in the main thread. Initializing Weights & Biases in a non-main thread can sometimes cause issues.

  7. Consult Weights & Biases Documentation and Support: If you suspect the issue is directly related to Weights & Biases, consult the documentation for any known issues or contact Weights & Biases support.

Unfortunately, without a specific code snippet or more details, it’s challenging to provide a more targeted solution. If you can isolate the issue to Weights & Biases specifically, please provide more details or a minimal code example that reproduces the problem.

Remember, issues like wait_for_tstate_lock() getting stuck are often complex and require a detailed investigation into the threading and synchronization aspects of your code.
