Hello, first time in Discord!

I am running my first app using llama-index to chat with my PDF. All my dependencies are up to date however I am getting this error:

ImportError: cannot import name 'BaseCache' from 'langchain' (/venv/lib/python3.11/site-packages/langchain/init.py)

I shortened the path, but I am inside a venv.

Has anyone had this issue and know the solution?

Thanks,
