Pytorch tensor clone detach

When data is a tensor x, torch.tensor () reads out ‘the data’ from whatever it is passed, and constructs a leaf variable. Therefore torch.tensor (x) is equivalent to x.clone ().detach () and torch.tensor (x, requires_grad=True) is equivalent to x.clone ().detach ().requires_grad_ (True).
