pytorch tensor/数据类型转化

pytorch 怎么进行数据类型的转化呢?

https://pytorch.org/docs/stable/generated/torch.Tensor.to.html

使用类方法 to,可以转化数据类型和数据postion,即可以把tensor在CPU和GPU之前进行转化

tensor = torch.randn(2, 2)  # Initially dtype=float32, device=cpu
tensor.to(torch.float64)

cuda0 = torch.device('cuda:0')
tensor.to(cuda0)

tensor.to(cuda0, dtype=torch.float64)

other = torch.randn((), dtype=torch.float64, device=cuda0)
tensor.to(other, non_blocking=True)
