Seems like a pydantic issue

LLogan M

Can you do this

LLogan M

pip install --upgrade pydantic==1.10.0

LLogan M

I ran into this earlier today too, langchain likely needs to limit their pydantic version, it's breaking their code

aashishsha

pip show pydantic

aashishsha

still same error

aashishsha

should I downgrde to some other version ?

LLogan M

One more thing

LLogan M

pip install --upgrade typing-extensions==4.5.0

LLogan M

If that doesn't work, I would start with a fresh venv

aashishsha

that error is gone but I think I need to upgrade my open-ai package as well , it is breaking there

aashishsha

which version of open ai works

aashishsha

pip show openai
Name: openai
Version: 0.26.5
Summary: Python client library for the OpenAI API
Home-page: https://github.com/openai/openai-python

aashishsha
