Webtorch.Tensor.detach Tensor.detach() Returns a new Tensor, detached from the current graph. The result will never require gradient. This method also affects forward mode AD gradients and the result will never have forward mode AD gradients. Note Returned Tensor shares the same storage with the original one.

A gradient can be None for few reasons. Either because the Tensor …
WebTensor.index_copy_(dim, index, tensor) → Tensor Copies the elements of tensor into the self tensor by selecting the indices in the order given in index. For example, if dim == 0 and index [i] == j, then the i th row of tensor is copied to the j th row of self. Webvar.clone ().data.cpu ().numpy () or var.data.cpu ().numpy ().copy () By running a quick benchmark, .clone () was slightly faster than .copy (). However, .clone () + .numpy () will create a PyTorch Variable plus a NumPy bridge, while .copy () will create a NumPy bridge + a NumPy array. numpy deep-learning pytorch tensor Share Improve this question
