ImportError: Could not import necessary dependencies to use OpenAI. Please install them with `pip install openai>=0.26.4`.

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

Thanks for filing this issue @amank94 - We didn't anticipate the release of OpenAI 1.0 during dev day and as such all notebooks automatically migrated to the latest which has breaking changes. For the time being Phoenix only supports OpenAI pre 1.0 but will migrate as part of #1716

The notebooks have been pinned via #1718 and should work out of the box. Thanks for your patience.
