PIL image.open() working for some images but not others

Maybe be the content is not actually synced to the disk. try Image.open(open("path/to/file", 'rb'))

You can use cv2 to read the image.

im = cv2.imread(path)

And, for opening/displaying, you can use:

cv2.imshow()

For

im = Image.open("path/to/file")

Try

im = Image.open(r"path/to/file")

That is, put a r before the path string.
