ValueError("type fp8e4nv not supported in this architecture. The supported fp8 dtypes are ('fp8e4b15', 'fp8e5')")

Set TORCHDYNAMO_VERBOSE=1 for the internal stack trace (please do this especially if you're reporting a bug to PyTorch). For even more developer context, set TORCH_LOGS="+dynamo"

Does anyone know the error?

The report names KSamplerAdvanced and a PyTorch/Triton compilation traceback, but no ComfyUI file or test. Start by reproducing the failure with the reported fp8e4nv architecture and inspect the KSamplerAdvanced entry point and surrounding PyTorch integration. Done means the reported workflow no longer raises the architecture-support error, with a regression test or documented compatibility result.
