This error is caused by a version mismatch between the OpenAI Python package and the typing_extensions library in your Databricks environment. The 'override' symbol is relatively new and only exists in typing_extensions version 4.5.0 and above; some environments (including Databricks) may still have an older version installed by default, even after installing or updating openai.​

How to Fix

• Upgrade typing_extensions directly in your Databricks cluster using:

   

  text

  %pip install --upgrade typing_extensions

  or, if you want to ensure a specific compatible version:

   

  text

  %pip install typing_extensions==4.7.1

• After upgrading, restart your Python kernel (or your Databricks notebook cluster) for the change to take effect.​

Notes

• This issue is common in cloud notebook environments, where library management can lag behind current package requirements.

• If you have done this already and still encounter the issue, force reinstall with:

   

  text

  %pip install --force-reinstall typing_extensions

These steps should resolve your ImportError so you can use the latest OpenAI package without issue.​
