pydantic.errors.PydanticUserError on CPU

[denmuslimov]

Trying to run a CPU-based model on Windows 11.
A clean installation following this instruction (changed the name of conda environment to avoid collisions):
https://github.com/h2oai/h2ogpt/blob/main/docs/README_WINDOWS.md

Tried running any model from the instruction below:
https://github.com/h2oai/h2ogpt/blob/main/docs/README_CPU.md

First, I got errors for missing libraries:

pip install fire
pip install langchain
pip install -U langchain-anthropic
pip install langchain-community
pip install langchain-experimental
pip install langchain-google-genai

After I got just this message:
