Summary of Changes

Hello @kylesayrs, 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 focuses on code cleanup and simplification within the pytorch_helpers.py module. It removes a function previously used to identify Mixture of Experts (MoE) models, indicating that this specific utility is no longer required or maintained. This change helps to reduce the codebase size and remove dead code, making the module more concise and easier to maintain.

Highlights

• Code Removal: The is_moe_model utility function has been completely removed from src/llmcompressor/modifiers/utils/pytorch_helpers.py.
• Dependency Cleanup: The unused import from torch.nn import Module has been removed, along with the is_moe_model entry from the __all__ export list.

Code Review

This pull request removes the unused is_moe_model function and its related import from src/llmcompressor/modifiers/utils/pytorch_helpers.py. This is a good cleanup as the function seems to have been superseded by the more robust MoE handling mechanism in llmcompressor.modeling.moe_context. The change improves code maintainability by removing dead code. The implementation is correct, and I have no further comments on the changes.
