AI suggestions as follow:

Based on your error message, the issue arises from the asynchronous request handling logic in the Gradio library, particularly when dealing with the AsyncRequest object. Attempting to access the non-existent _json_response_data attribute has led to an AttributeError.

This error can broadly be categorized into the following aspects:

Error Source:

The error occurs in the queueing.py file of Gradio, specifically within the process_events coroutine. When handling events in the queue, the program tries to access response.json, but the returned object does not have this attribute. The response is part of the AsyncRequest object, but due to the absence of the _json_response_data attribute, the program raised an AttributeError.

Possible Causes:

Version Incompatibility: The version of the Gradio library or its dependencies might be incompatible with other libraries in the project, causing the structure of the AsyncRequest object to differ from what is expected.

Incomplete Initialization: The AsyncRequest object might not have been properly initialized, resulting in the absence of the _json_response_data attribute.

Network Request Failure: If the request from Gradio fails, it could lead to an incomplete object being returned, which could also result in this error.

Suggested Solutions:

Check Gradio Version: Confirm that you are using the latest version of Gradio. You can update Gradio by running the following command:

pip install --upgrade gradio

Check for Dependency Version Conflicts: Use pip freeze to check the versions of all dependencies in your project and ensure there are no conflicts or incompatible versions with Gradio or its related dependencies.

Fix or Modify Code: If you are a developer of the library or have access to modify the source code, consider adding exception handling in the process_events method to check whether the returned object has the _json_response_data attribute:

if hasattr(response, '_json_response_data'): return response._json_response_data else:

Handle the lack of this attribute, potentially logging an error or returning a default value

return {}

Submit an Issue: If you suspect this is a bug within Gradio, or if the issue persists after upgrading, consider submitting an issue on the Gradio GitHub repository. Describe your problem and your environment configuration to assist the developers in resolving it.

You can troubleshoot and resolve the issue step by step based on these suggestions. If you encounter any more specific problems, I can continue to help you debug further.

I think it is a gradio problem,because I never change my code

A minimal reproduction please. There is a lot going on here.
