👋 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.

Summary of Changes

Hello @simon-mo, 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 ModuleNotFoundError that was occurring during documentation builds because the gguf module was not available in the build environment. The change implements a lazy import mechanism for gguf in weight_utils.py, making it an optional dependency and ensuring that the documentation can be built successfully without requiring gguf to be installed.

Highlights

• Dependency Handling: Modified the import strategy for the gguf module from an eager, top-level import to a lazy import within a try-except block. This change prevents ModuleNotFoundError when gguf is not installed, specifically addressing issues during documentation builds.

Code Review

This pull request addresses a ModuleNotFoundError for the gguf package, which was breaking the documentation build. The change correctly refactors the gguf import to be lazy, loading it within a try...except ImportError block. This is a common and appropriate pattern for handling optional dependencies and is consistent with how other packages are handled in the same file. The implementation is correct and effectively resolves the build issue.
