cuDNN Frontend error: No valid engine configs for Matmul_MUL_Reduction_SUB_EXP_Reduction_LOG_ADD_DIV_Matmul_ #9947
Description
Custom Node Testing
- I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)
Your question
Updated my system & GPU drivers this morning, it appears to have broke Comfy. KSampler now doesn't run with this error message:
cuDNN Frontend error: No valid engine configs for Matmul_MUL_Reduction_SUB_EXP_Reduction_LOG_ADD_DIV_Matmul_

{"engineId":1,"smVersion":890,"knobChoices":{"CUDNN_KNOB_TYPE_KERNEL_CFG":3}}
What happened? It's running on NVIDIA RTX 4060Ti 16GB, Linux Pop OS latest, driver version 580.82.07
CUDA version: 11.5.119
Pytorch version: 2.9.0.dev20250901+cu129
