👋 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.

🚀

Thanks for the update. It would also be good to know how to install torchvision for TPU, I need this for vision

Does it need force-merge?

Please also make the change from https://github.com/vllm-project/vllm/pull/13761/files#diff-1a5f6d7d455c2ef7f4db62c143f71c11e2b3179bc6269b901272e1347d2e473d, one of the files has moved since the TPU tests last ran

btw this is still not compatible with uv due to the version metadata not matching the name

uv pip install -r requirements-tpu.txt

warning: Ignoring unsupported option in `requirements-tpu.txt`: `--pre` (hint: pass `--pre` on the command line instead)
