WebSep 22, 2024 · At times in Pytorch it might be useful to shuffle two separate tensors in the same way, with the result that the shuffled elements create two new tensors which maintain the pairing of elements between the tensors. An example might be to shuffle a dataset and ensure the labels are still matched correctly after the shuffling. WebJan 21, 2024 · Yeah, it's expecting that objects that fall down to that branch don't have view-based semantics for those indexing operations. There used to be fewer objects with view-based semantics. We take care of the known view-based-semantics for the common use case of multidimensional ndarrays in the previous branch.But to do so, we need to rely on …
