Summary of Changes

Hello @wangxiyuan, 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 streamlines the vllm-ascend codebase by eliminating a redundant patch file and its corresponding import. The removed patch, patch_bert.py, previously addressed aclgraph limitations related to shift operators for BERT token type IDs. Its removal indicates that this specific workaround is no longer necessary, simplifying the project structure and reducing maintenance overhead.

Highlights

• File Removal: The patch_bert.py file, which provided custom token type ID handling for BERT models, has been completely removed from the project.
• Import Cleanup: The import statement for patch_bert.py was removed from vllm_ascend/patch/worker/__init__.py, reflecting its removal.

Code Review

This pull request removes the patch_bert.py file and its corresponding import. This patch was a workaround for hardware limitations that are presumably now resolved. The change is a straightforward code cleanup.

While the code change itself is fine, the pull request title and description do not follow the repository's contribution guidelines. The title should be formatted as [Branch][Module][Action] Title, and the description template should be filled out to provide context for the change. Adhering to these guidelines is important for project maintainability. For example, a more descriptive title could be [main][Worker][Refactor] Remove obsolete BERT patch. The description should clarify why this patch is no longer needed and how the change was tested.
