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 addresses a breaking change in JAX 0.7.1 by updating how the jax.experimental.layout.Layout class is instantiated. The core change involves adapting to a renamed argument, ensuring that the codebase remains functional and compatible with both newer and older versions of the JAX library.

Highlights

• JAX API Compatibility: Updated the usage of jax.experimental.layout.Layout to account for the _tiling argument being renamed to tiling in JAX version 0.7.1.
• Backward Compatibility: Implemented version-aware logic using jax.__version_info__ to dynamically select between the tiling (for JAX 0.7.1+) and _tiling (for older JAX versions) arguments, ensuring the code remains compatible across different JAX environments.
• Code Refinement: Introduced a local layout variable to encapsulate the version-dependent LayoutClass instantiation, improving readability and maintainability in both the main implementation and its test utility.

Code Review

This pull request addresses a breaking change in JAX version 0.7.1 by renaming the _tiling argument to tiling for jax.experimental.layout.Layout. The changes are applied to both the main implementation and the corresponding test file. My feedback focuses on improving code maintainability by reducing duplication in the newly added conditional logic. I've suggested refactoring the LayoutClass instantiation to avoid repeating common arguments, which should make the code cleaner and easier to maintain.

[gemini-code-assist]

To improve maintainability and reduce code duplication, you can factor out the common arguments for LayoutClass into a dictionary. This makes the conditional logic cleaner and avoids repeating arguments.

common_kwargs = {"major_to_minor": (0, 1)}
layout = (
    LayoutClass(**common_kwargs, tiling=((8,),))
    if jax.__version_info__ >= (0, 7, 1)
    else LayoutClass(**common_kwargs, _tiling=((8,),))  # type: ignore
