Hi,

First, thanks to the developers for making and releasing this model under a real open source license!

The code didn't work for me on the Nvidia B200 GPU. It also had some older dependencies.

I did an update repo so it runs on the B200:

  • Python 3.12.
  • Torch 2.11.
  • CUDA 13.
  • Flash Attention 4.

My repo is here:

Happy hacking,

-Jeff
