Why is the 'Beta' object missing the chat attribute?

I’m using the latest openai python sdk.

I got the same error and realized using langfuse wrapper instead of the one from openai.
Try json.load() instead if it is the case.

Langfuse doc: integrations/openai/python/structured-outputs
Disclaimer: Link post is not allowed here.

I got the same error, apparently this seems to be the only endpoint that supports structured outputs for now. Tried batch, assistants as well as completions and it doesn’t support despite latest SDK

Problem solved. Just update python to 3.12.
I don’t know why.

I tried after with python upgrade to 3.12, didn’t work

I’m already on python 3.12.4 and seeing the same issue: ‘Beta’ object has no attribute ‘chat’

Ok, make sure that you have version 1.40 (and beyond) of the openai package. After updating the package it works.

Still getting this issue. Have openai version 1.40.5 and python version 3.12.4

Updating python to 3.12.4 and openai package to 1.40.0 worked for me.

This is the right answer, both the libraries need to be upgraded.

This is not working after upgrading both python and openai libraries

I have the same issue.

Interestingly the code runs in a jupyter notebook cell, but not when wrapped in a FastAPI endpoint.

Using same python interpreter and openai version for both.

  • Python 3.12.2
  • Openai 1.42.0

I get this error when using openai 1.42.0 but not when I downgraded to 1.40.0 with pip install openai==1.40.0.

hop on one leg, quack like a duck, and spin around. This worked for me. smh

I have the same issue as rhruby.
When running it as a script it works, but when wrapped in FastAPI I get the issue.

It works with Python 3.10. after upgrading openai to 1.43.0. Keep in mind that you have to restart the kernel after pip install, if you’re using Jupyter notebook.

If you want to keep an old Python version such as Python 3.9, use pip install openai==1.47.0 --upgrade. Then, use pip freeze to double-check that the right version was installed.

Python on the bleeding edge that is not in the bugfix stage is not recommended, though, unless you have strong justification. You may inadvertently use a method that breaks backwards-compatibility, causing the same issues for others.

Here’s what one can do for assurance that you are working with the same platform as a developer might, or simulate a brand new Python install that just had installed a pypi module fresh: upgrade ALL the openai dependencies to the latest supported.

For upgrading all, by current version limitations of OpenAI requirements:

pip install --upgrade --upgrade-strategy eager regex "charset-normalizer<4" "idna" "urllib3<3" "certifi" "requests" "anyio<5" "distro<2" "sniffio" "h11<0.15" "httpcore==1.*" "httpx<1" "annotated-types" "typing-extensions<5" "pydantic-core==2.20.1" "pydantic<3" "jiter<1" "tqdm" "colorama" "openai" "tiktoken"

The above progresses from lower level dependencies, so a later module version with updated requirements could override what was just installed before. Only as a side effect, it addresses any version concerns about using “openai.Client().beta”

Had the same problem, fixed it when I updated to python 3.12
