#12134

Merged

Requantizing fp8 weights into NANOO format on ROCm platform.
Conditionally using e4m3fnuz where appropriate.

This is essential for DeepSeek V3 support

👋 Hi! Thank you for contributing to the vLLM project.
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 do one of these:

• Add ready label to the PR
• Enable auto-merge.

🚀

Makes sense and LGTM. With these changes have you validated DSv3 on MI300?

In a combination with the flash attention version from ROCm/vllm, which will be coming in the following weeks, together with LLama3.2 support

So converting the weights this way was required to turn nans into a reasonable PPL score.
