Dtype torch.long是什么意思
WebMay 5, 2024 · In modern PyTorch, you just say float_tensor.double () to cast a float tensor to double tensor. There are methods for each type you want to cast to. If, instead, you have a dtype and want to cast to that, say float_tensor.to (dtype=your_dtype) (e.g., your_dtype = torch.float64) 7 Likes. gt_tugsuu (GT) May 21, 2024, 6:05am 12. WebApr 27, 2024 · Possibly related, but keep in mind that Tensor.to(dtype=torch.long) and Tensor.long() are not in-place operations, so you need to assign the value returned from them. For example you need to do x = x.long(), just putting x.long() by itself won't accomplish anything. – jodag. Apr 27, 2024 at 18:15
