torch.cuda.seed
torch.cuda.seed()
Sets the seed for generating random numbers to a random number for
   the current GPU. It's safe to call this function if CUDA is not
   available; in that case, it is silently ignored.
Warning:
 If you are working with a multi-GPU model, this function will
 only initialize the seed on one GPU.  To initialize all GPUs, use
 "seed_all()".
