'numpy.ndarray' object has no attribute 'imshow'

This:

for i in ax:
    ax[i].imshow(img, interpolation='none')

doesn't make sense because I isn't the index. It's one of the axis objects.

And your first case is wrong because even though you loop over the items, you call the function on ax, not the individual axes.

Do this:

for a in ax:
    a.imshow(img, interpolation='none')

just add this command before "ax.flatten()" before your code

ax = ax.flatten()
for a in ax:
    a.imshow(img, interpolation='none')
plt.show()
