Whether it is worthwhile to create cuda C for CNN or whether torch.cuda is sufficient

I’m new and have been learning cuda C. I have a minor question: because I know that pytorch.cuda is essentially a wrapper for Cuda , is it worthwhile to utilize Cuda C to train a simple CNN or torch.cuda is enough

Hi @ngogiahuy20012004 ,
This forum talks about cudnn related issues.
Cuda or Pytorch forums might be able to assist better.
