About the input image, it seems not all image can be handled without errors

[drrobincroft]

I have tried some my own images as input for DIP. It seems some images would lead to errors like
Argument #6: Padding size should be less than the corresponding input dimension, but got: padding (1, 1) at dimension 2 of input 4
or
The size of tensor a (3) must match the size of tensor b (4) at non-singleton dimension 1
I cannot tell the difference among the input images, except for contents.

Is there some preconditions for the input image? This is really wired.
