pytorch how to remove cuda() from tensor
I got TypeError: expected torch.LongTensor (got torch.cuda.FloatTensor). 

How do I convert torch.cuda.FloatTensor to torch.LongTensor?

  Traceback (most recent call last):

    adv_embedding = torch.LongTensor(adv_embedding)

You have a float tensor f and want to convert it to long, you do long_tensor = f.long()

You have cuda tensor i.e data is on gpu and want to move it to cpu you can do cuda_tensor.cpu().

So to convert a torch.cuda.Float tensor A to torch.long do A.long().cpu()
