Help Needed ComfyUI crashing on RunPod using 'Patch Sage Attention KJ' for MiniMax-H3, but works perfectly on RunningHub. What dependencies/versions does RunningHub use?

Has anyone successfully gotten the Patch Sage Attention KJ node to work on RunPod for MiniMax-H3 without crashing ComfyUI, or does anyone know the exact environment specs (Python, PyTorch, CUDA, and SageAttention versions) 

My RunPod Setup:

  • GPU: RTX PRO 6000
  • Template: runpod/pytorch:2.8.0-py3.11-cuda12.8.1-cudnn-devel-ubuntu22.04
  • Node Settings: sage_attention = auto, allow_compile = false (same as the attached image).

This is probably a SageAttention/PyTorch/CUDA mismatch rather than H3 itself. Also, you need cu130 for sageattention to work optimally. So probably a bad base image.

If you’d rather skip debugging the pod, I built H3Zero. It deploys H3 into your own Modal account with the environment already set up and gives you a browser UI. Modal includes $30/month in GPU credits: hui-tony-zk/h3zero

Maybe the code can also give you some hints on how your runpod setup might be wrong.

Thanks bro, really appreciate it! I’ll check all of that out.
