Not fixing the import lib warning as it is not explicitly related to pydantic.

Regarding pydantic v1 compatibility https://github.com/BerriAI/litellm/pull/3600#discussion_r1598686881

Openai (1.25.1) is using pydantic v2 https://github.com/openai/openai-python/blob/aed1e43745cd6358b4bafd3a39b3dfeee5e31a03/requirements.lock#L40

Thanks for this @lj-wego,

Can you confirm it passes on the list of tests the previous PR attempting to address this failed on - https://github.com/BerriAI/litellm/pull/3664

1. tests/test_ratelimit.py
2. test_organizations.py/test_organization_new
3. Failed linting on types/completion.py, types/router.py, types.embedding.py

[lj-wego]

1. tests/test_ratelimit.py

[lj-wego]

test_organizations.py/test_organization_new

took awhile to figure out what needed to be ran but managed to set up a local docker postgres, prisma migrate and ran the server, and then the test.

results

[lj-wego]

Failed linting on types/completion.py, types/router.py, types.embedding.py

i believe this fixes this https://github.com/BerriAI/litellm/pull/3670#discussion_r1604283980

[lj-wego]

@krrishdholakia can confirm it works on my machine.

[rickyyx]

Thanks! This is really cogging our CI logs. :(

[lj-wego]

Merged new changes and updated one pesky class Config that was introduced.

Hands tied here for the CI since: a. i don't have most of the services API keys to properly run the full test/lint suite b. i don't use circle ci so can't reproduce the testing workflow.

[krrishdholakia]

Merging in - i'll let you know if there's any issues on ci/cd @lj-wego

Thank you again for your help here!

[lj-wego]

@krrishdholakia i notice the CI failing and this might be the issue.

installs older pydantic

[lj-wego]

Added a PR here to address this. Unless this is reverted 😓
