WebMar 14, 2024 · 在这种情况下，可以使用`detach()`方法来创建一个新的张量，该张量与原始张量具有相同的值，但不再与计算图相关联。然后，如果需要将该张量转换为NumPy数组，可以使用`numpy()`方法。因此，`tensor.detach().numpy()`的含义是将张量分离并转换为NumPy数组。 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). minecraft wooden house idea
