Witryna5 gru 2024 · When you permute (siz_img, [3 1 2 4]) then the second dimension would move to the third dimension, so the output would be 1 x 1 x length (siz_img) = 1 x 1 x 2. You then try to imshow () that 1 x 1 x 2, which fails because imshow () can only handle arrays that are either 2D or 3D with the third dimension being length 3.

To see how many images are in our training set, we can check the length of the dataset using the Python len () function: > len (train_set) 60000. This 60000 number makes sense based on what we learned in the post on the Fashion-MNIST dataset. Suppose we want to see the labels for each image.

WitrynaSo in my code, there is no need for permute, or stuff like that. Also, the output of make_grid is an image (in a tensor form of course) so in order to get this to work I had to simply convert it to numpy and transpose the axis so matplotlib can display it properly: new_img = torchvision.utils.make_grid(f).numpy().transpose(1,2,0) plt.imshow(new ...
