I tried installing different versions of pydantic, pydantic_settings with chromadb Version: 0.3.26 but nothing worked. Would like to know the compatible versions of pydantic and pydantic_settings. I am using python 3.10

Lowering the version of pydantic might help

pip list | grep pydantic

pydantic                                 2.5.1
pydantic_core                            2.14.3
pydantic-settings                        2.1.0
