FIX: NVIDIA 5090: ComfyUI Error v0_17_1 cudaErrorNoKernelImageForDevice

[Ell10ttHar5h]

I am using portable v0_17_1 and started getting this errors

cudaErrorNoKernelImageForDevice

here is the Fix that worked for me.

navigate to the embedded python install: ComfyUI_windows_portable_nvidia_cu126_v0_17_1\ComfyUI_windows_portable\python_embeded

open your terminal here and run this command upgrade your torch config:

.\python.exe -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128 --force-reinstall --no-deps

I was able to run models with no cudaErrorNoKernelImageForDevice errors
