WebPixelShuffle. Rearranges elements in a tensor of shape (*, C \times r^2, H, W) (∗,C × r2,H,W) to a tensor of shape (*, C, H \times r, W \times r) (∗,C,H ×r,W × r), where r is an upscale factor. This is useful for implementing efficient sub-pixel convolution with a stride of 1/r 1/r. See the paper: Real-Time Single Image and Video Super ...

Shuffle elements of tensor - PyTorch Forums
WebMay 11, 2024 · Each sample in the batch is of shape [4, 300]. So, shape of my batch is [64, 4, 300]. I want to randomly shuffle the elements of the batch. In other words, I want to … 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. birthday journey around the sun
How to Shuffle Columns or Rows of Matrix in PyTorch?
WebMay 14, 2024 · As an example, two tensors are created to represent the word and class. In practice, these could be word vectors passed in through another function. The batch is then unpacked and then we add the word and label tensors to lists. The word tensors are then concatenated and the list of class tensors, in this case 1, are combined into a single tensor. WebMar 12, 2024 · Add a comment. 1. Just generalising the above solution for any upsampling factor 'r' like in pixel shuffle. B = A.reshape (-1,r,3,s,s).permute (2,3,0,4,1).reshape (1,3,rs,rs) … WebApr 22, 2024 · I have a list consisting of Tensors of size [3 x 32 x 32]. If I have a list of length, say 100 consisting of tensors t_1 ... t_100, what is the easiest way to permute the tensors in the list? x = torch.randn (100,3,32,32) x_perm = x [torch.randperm (100)] You can combine the tensors using stack if they’re in a python list.
