AttributeError: 'NoneType' object has no attribute 'shape'

What is this error??

Traceback (most recent call last):
  File "", line 1717, in shape
    height, width = input.shape
AttributeError: 'NoneType' object has no attribute 'shape'

This is the code:

        input = cv2.imread('IMAGES/UAV.tif') #, cv2.IMREAD_UNCHANGED)        
        height, width = input.shape
        print("HEIGHT:", height)
        print("WIDTH:", width)

At a guess imread has failed and input is a NoneType instead of a numpy array. As such it doesn’t have a shape attribute.


These are the pixels’ colors range from the QGIS where I tested the .tif file colors Can this be the problem?

even on read failure, you can avoid the exception:
height, width = np.shape(input)
# -> height == width == 0

but please, DO CHECK each imread() call, opencv does not throw , but returns invalid images(None) on failure (something, python noobs NEVER expect)

Yes, indeed, print(input) returns “None”! Any ideas?

post the exact image file, no editing at all, none. then we can investigate.
