Shuffle torch tensor
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. Webtorch.nn.functional.pixel_shuffle¶ torch.nn.functional. pixel_shuffle (input, upscale_factor) → Tensor ¶ Rearranges elements in a tensor of shape (∗, C × r 2, H, W) (*, C \times r^2, H, W) (∗, C × r 2, H, W) to a tensor of shape (∗, C, H × r, W × r) (*, C, H \times r, W \times r) (∗, C, H × r, W × r), where r is the upscale ...

WebDataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples. PyTorch domain libraries provide a number of pre-loaded datasets (such as FashionMNIST) that subclass torch.utils.data.Dataset and implement functions specific to the particular data.

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 …
