Summary of Changes

Hello, 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 bug by ensuring that tensors maintain a contiguous memory layout after transpose operations within the qwen3_next.py and qwen3_5.py models. This change is crucial for preventing potential issues with subsequent tensor manipulations that expect contiguous data, thereby improving the stability and correctness of the model's computations.

Highlights

• Bug Fix: Add .contiguous() calls after transpose operations in qwen3_next.py and qwen3_5.py to ensure correct tensor memory layout for subsequent operations.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• swift/megatron/model/gpts/qwen3_next.py
  • Ensured tensor contiguity after transpose operation.
• swift/megatron/model/mm_gpts/qwen3_5.py
  • Ensured tensor contiguity after transpose operation.

Code Review

This pull request applies a bugfix across two model files, qwen3_next.py and qwen3_5.py. The change involves adding a .contiguous() call after a transpose operation on the res tensor. This ensures the tensor has a contiguous memory layout before being passed to reduce_scatter_to_sequence_parallel_region, which likely prevents runtime errors related to tensor strides. The fix is consistent and correctly applied in both locations.
