ComfyUI | fatal error | crashes completely when the sampler starts working

[vallestutz]

Hey creative diffusers community,

since ~2 weeks, I'm getting a fatal error, which shuts down Comfy completly. Smaller workflows seem to work until they get to big. Once my workflow just worked fine UNTIL I added a third ControlNet. I found a couple of people, which get the same error but couldn't figure out similarities yet.

When I used ComfyUI inside of StabilityMatrix, I got this error line:

Process finished with exit code -1073740791

I hoped to get rid of the problem, using the normal version (not the portable one) but here I get this error line(s):

C:\actions-runner\_work\pytorch\pytorch\builder\windows\pytorch\aten\src\ATen\native\cuda\IndexKernel.cu:92: block: [273,0,0], thread: [1,0,0] Assertion `-sizes[i] <= index && index < sizes[i] && "index out of bounds"` failed.

For trying out, here is my Workflow.

system information:

• Windows 11
• Nvidia RTX 3090 TI
• AMD Ryzen 9 5900X
• 64GB RAM

Its the python version. comfy works only proper with 3.10.11. Have had a hard time to figre this out https://github.com/kijai/ComfyUI-SUPIR/issues/96 My system: Windows 11 Nvidia RTX 4070 AMD Ryzen 9 5900X 32GB RAM

I installed https://www.python.org/downloads/release/python-31011/ and reinstalled ComfyUI but the error keeps the same

What do you mean exactly? I reinstalled ComfyUI completly, including the step of installing the requirements.txt Also reinstalled the custom nodes trough the manager. Or do I have to install them in a special way?

StabilityMatrix

1st of all pls proceed the command pip install -r requirements.txt for the custom nodes in ur workflow too. If the wf is not working afterwards the problem might be caused by StabilityMatrix. StabilityMatrix uses an embedded python version. So for crosscheck try to run ur workflow from the clean comfy under http://127.0.0.1:8188
