RuntimeError when starting `shai`

Closed this issue · 2 comments

I installed shai using pip, as suggested. I am using Python 3.10 and macOS Ventura.
I have the OPENAI_API_KEY environment variable setup correctly (as far as I can tell). I also tried to set the config.json, but the outcome is the same.

Here is the output when I try to execute shai:

$ shai

I recall this was an issue with LangChain <> Pydantic interaction. Could you run pip install langchain pydantic -U and try again?
