Here’s a MWE: I have tried both shrink and fraction but none of them seem to do the trick. I am attaching the output. Any help is greatly appreciated! Answe…
How can I generate and display a grid of images in PyTorch with plt.imshow and torchvision.utils.make_grid?
I am trying to understand how torchvision interacts with mathplotlib to produce a grid of images. It’s easy to generate images and display them iteratively: However, displaying these images in a grid does not seem to be as straightforward. Even though PyTorch’s documentation indicates that w is th…

Is it possible to a) remove the ticks but leave the label in the same location and b) add gridlines betwe…
