TypeError: Type is not JSON serializable: numpy.float64

[xiansir-zhe]

I'm new to python and very interesting in this project :
When i just run the webLangChain locally, i meet this problem. Then another problem occured:

Retrying langchain_community.chat_models.openai.acompletion_with_retry.._completion_with_retry in 4.0 seconds as it raised APIConnectionError: Error communicating with OpenAI.
Task exception was never retrieved
future: <Task finished name='Task-99' coro=<<async_generator_athrow without name>()> exception=APIConnectionError(message='Error communicating with OpenAI', http_status=None, request_id=None)>

The complete logs as follows:
ERROR: Exception in ASGI application

The above exception was the direct cause of the following exception:

i doubt that if there is something wrong with some packages, maybe i installed the incompatible version but i idk which one.
this is my packages info:
