Installing pydantic>=2.4.0 would cause error and fail to load model

[Luodian]

System Info

The error would be as

Failed to import transformers.generation.utils because of the following error (look up to see its traceback): 'FieldInfo' object has no attribute 'required'

I spent a lot of time to spot it's the version change from the installation of upgrading gradio and it caused pydantic==1.10.7 to pydantic==2.4.2.

I downgraded to 1.10.7 then could run smoothly as usual.

Who can help?

No response

Expected behavior

Hi @Luodian, thanks for raising this issue!

I looks like we might have to pin pydantic in our setup.py - WDYT @ydshieh?

Hi @Luodian

We do have "pydantic<2", in out setup.py

Related #24596

Not sure how much we can do with pydantic 2 so far.

[Luodian]

oh know that, thanks! I think the pydantic>2 comes from upgrading gradio.

Eventually, if pydantic>=2 is used by many libraries, we might consider to update the requirement (as long as not so many things breaking 😄 )
