extent analysis

TL;DR

Investigate using an alternative loading method or format, such as eager or fastsafetensors, to accelerate loading times for the fp4 format in the vllm environment.

Guidance

  • Check the vllm documentation for any updates or recommendations on loading models in fp4 format, as the current method is taking 30-40 minutes.
  • Look into integrating the specific model with vllm, potentially by exploring the model's documentation or seeking guidance from the vllm community.
  • Verify if there are any known issues or limitations with loading fp4 format models in the B300 environment.
  • Consider reaching out to the vllm support or community for further assistance, as the issue may be specific to the environment or model being used.

Notes

The provided information lacks specific technical details, making it challenging to provide a definitive solution. Further investigation and exploration of the vllm documentation and community resources are necessary to resolve the issue.

Recommendation

Apply workaround: Investigate alternative loading methods or formats to accelerate loading times, as the current approach is taking an excessively long time.
