hello, i am using your tutorial but it

Try updating maybe, and restarting your notebook? I cant replicate this

pip install -U llama-index-llms-openai ?

If you can replicate in a google colab, I could debug from there, but it works for me currently with latest versions

okay, thanks... that;s a weird bug.. now it works.

We switched to pydantic v2, and it caused some awkward bugs
