【pytorch】——PixelUnshuffle_pixel unshuffle

pytorch, PixelUnshuffle

直接看例子吧，没有画图

>>> import torch
>>> a = torch.arange(32).reshape(1, 2, 4, 4)
>>> a
tensor([[[[ 0,  1,  2,  3],
          [ 4,  5,  6,  7],
          [ 8,  9, 10, 11],
          [12, 13, 14, 15]],

         [[16, 17, 18, 19],
          [20, 21, 22, 23],
          [24, 25, 26, 27],
          [28, 29, 30, 31]]]])
>>> import torch.nn as nn
>>> shuffel = nn.PixelUnshuffle(2)
>>> shuffel(a)
tensor([[[[ 0,  2],
          [ 8, 10]],

         [[ 1,  3],
          [ 9, 11]],

         [[ 4,  6],
          [12, 14]],
