👋 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.

Okay to revert for now to fix TPU build, fyi @hmellor

[hmellor]

I'd like this change to be reinstated at some point, but if it unblocks TPU I'm happy to revert for now

I see a similar breakage on ROCm. hf-xet exists there, the issue seems to be related to how setuptools treats dependencies
In the def requires of the dist-packages/pkg_resources/init.py hf-xet is being renamed to hf_xet for some reason, and so there is a key exception

[gshtras]

Changing to
huggingface-hub[hf_xet] >= 0.30.0 # Required for Xet downloads.
seems to work
