@svekars Thanks for the preview.

It's so weird that the preview shows a KeyboardInterrupt:

I also noticed that the img = Image.fromarray(img_array); img.show() is not displaying the images. Do you know if that's possible?

[svekars]

img = Image.fromarray(img_array); img.show()

Use matplotlib.plt.imshow(img_array); plt.show() should work
