Summary of Changes

Hello @ch-wan, 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 resolves a logical error in a conditional statement within the model execution component. The change ensures that the require_gathered_buffer check is properly evaluated by invoking it as a function, which is crucial for accurate buffer management under specific conditions. This fix prevents potential incorrect behavior related to buffer gathering.

Highlights

• Condition Check Fix: Corrected the require_gathered_buffer condition by calling it as a function with self.server_args as an argument, instead of treating it as a boolean variable.

Code Review

This pull request addresses a subtle but important bug in _forward_raw. The condition check for require_gathered_buffer was missing the function call, causing it to always evaluate to True. The fix correctly calls require_gathered_buffer(self.server_args), ensuring that adjust_num_token_non_padded_for_attn_tp is only executed when necessary. This is a good catch and the change is correct. I've checked for similar issues with related functions and found no other problems. The code looks good to merge.
