v2.7.0b1 throws error when using OpenAI SDK

[willbakst]

Initial Checks

• I confirm that I'm using Pydantic V2

Description

Trying to generate a simple chat completion (as in below code example) throws:

AttributeError: type object 'Generic' has no attribute '__annotations__'

I've confirmed that this does not happen with previous versions >2.0 and <2.7

Example Code

from openai import OpenAI


client = OpenAI(api_key="NONE")  # error is thrown before `api_key` is needed
res = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "system", "content": "Say this is a test"}],
)
print(res)

Great catch, thank you. We'll look into it.

@willbakst,

Could you please provide the full traceback? Thanks!

[dmontagu]

Also, could you share the full output of pip freeze? We're having trouble reproducing this, wondering if there's a chance it's related to other dependency versions (in particular, the version of the openai SDK).

[dmontagu]

Oh nevermind, I was able to reproduce it once I switched to python 3.9

[sydney-runkle]

We've found the issue and will open a PR with a fix shortly! Should be fixed for 2.7 :).

[willbakst]

Awesome, thank you! Would love to test a v2.7.0b2 as well unless you're releasing 2.7 soon and thus no need :)

[sydney-runkle]

@willbakst I think this is a small enough fix that we'll just go ahead with 2.7, but perhaps you could test against main to confirm things are working as expected on your end?

[dmontagu]

@willbakst I also confirmed I was able to run your snippet (substituting a valid API key) and successfully get output (and it even had content='This is a test.' 😄) with the change in #9193.
