👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Code Review

This pull request updates the Triton dependency for ROCm builds from version 3.2 to 3.3.0. The change is straightforward and aligns with the goal of enabling Triton 3.3, which is compatible with PyTorch 2.7.0 as listed in the same requirements file. The new version specifier is explicit and pinned, which is a best practice for ensuring reproducible builds. The change appears correct and self-contained.

Looks good. Unfortunately, AFAIK, this build path isn't covered in CI. To test changes to this file I usually just run pip install -r requirements/rocm-build.txt --no-cache-dir to make sure everything works.

Looks like this works:

uv pip install -r requirements/rocm-build.txt --no-cache-dir --index-strategy unsafe-best-match
