Summary of Changes

Hello @hertschuh, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the error handling for jax and jax.experimental.sparse imports within the distributed_embedding_test.py file. Instead of explicitly setting jax and jax_sparse to None when an ImportError occurs, the code now simply uses a pass statement. This adjustment is intended to resolve issues and ensure the test runs more reliably across various environments, preventing potential failures related to the absence or specific configuration of jax.

Highlights

• Import Error Handling: Modified the except ImportError block for jax and jax.experimental.sparse imports in distributed_embedding_test.py to use pass instead of assigning None to the module variables.
• Environment Compatibility: This change aims to improve compatibility and functionality in certain environments where jax imports might behave differently, as noted in the PR description.

Code Review

This pull request aims to fix an issue with optional jax imports in a test file. The change correctly avoids nullifying the jax import if only the jax_sparse import fails. However, it introduces a new issue where jax and jax_sparse will be undefined if their imports fail, potentially leading to NameError exceptions. A more robust approach would be to handle the imports separately to ensure the variables are always defined, even if as None.
