Thanks for contributing an answer to Stack Overflow! and in albanD's remarks that I quoted in the question: In other words, the detach method means "I don't want gradients," and it is impossible to track gradients through numpy operations (after all, that is what PyTorch tensors are for!). Have a question about this project? cpu --> allocate tensor in RAM How to print value of tensorflow.python.framework.ops.Tensor in Tensorflow 2.0? However, torch.tensors are designed to be used in the context of gradient descent optimization, and therefore they hold not only a tensor with numeric values, but (and more importantly) the computational graph leading to these values.

Strides are a list of integers: the k-th stride The Dive into Deep Learning (d2l) textbook has a nice section describing the detach() method, although it doesn't talk about why a detach makes sense before converting to a numpy array. Adding on to what @Dwight_Foster said, you can do my_file3 = (x_mean[1].detach() if x_mean[1].requires_grad else x_mean[1]).cpu().numpy() to make it work in any case. Yes, the new tensor will not be connected to the old tensor through a grad_fn, and so any operations on the new tensor will not carry gradients back to the old tensor.
