how to fix CUDNN_STATUS_EXECUTION_FAILED

[ezhouyang]

Error cuDNN error: CUDNN_STATUS_EXECUTION_FAILED Failed inference for RealESRGAN: CUDA error: unknown error CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Compile with TORCH_USE_CUDA_DSA to enable device-side assertions.
