device (torch.device, optional) – the desired device of returned tensor. Default: if None, uses the current device for the default tensor type (see torch.set_default_tensor_type()). device will be the CPU for CPU tensor types and the current CUDA device for CUDA tensor types. requires...
torch.device torch.device代表将torch.tensor分配到的设备的对象(简单点说,就是分配到你的CPU还是GPU上,以及哪块GPU上)。 可通过字符串形式使用: torch.device('cuda:0') device(type='cuda', index=0) 也可以通过字符串和设备编号的形式使用: torch.device('cuda',0) ...

每个torch.Tensor都有torch.dtype,torch.device,和torch.layout。 torch.dtype torch.dtype是表示torch.Tensor的数据类型的对象。PyTorch有八种不同的数据类型: 使用方法: >>> x = torch.Tensor([[1,2,3,4,5], [6,7,8,9,10]])>>> print x.type() ...
