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

I have the same issue. can help me ?

[mohammed-Emad]

Check the cam or check the video used,
This error does occur when there is a problem reading the camera or video.

He inquires about the shape class,
But the value of the frame now equals None,
There are no classes there so this is a mistake.
It was supposed to make a condition to alert you to the lack of input to understand the problem without entering into other labyrinths.

For example

if ret==True:
   ...your code..
else:
  error input and break

or real example

while(True):
        # get the current frame
        (grabbed, frame) = camera.read()
        if not grabbed: #is true
            print("Error input chk your[cam Or video]")
            break
        # resize the frame
        frame = imutils.resize(frame, width = 700)

        # flip the frame so that it is not the mirror view
        frame = cv2.flip(frame, 1)

        # clone the frame
        clone = frame.copy()

        # get the height and width of the frame
        (height, width) = frame.shape[:2]

Thanks, good luck

or cam error port?

camera = cv2.VideoCapture(0)

try -1 vs 0

camera = cv2.VideoCapture(-1)

Hey @mohammed-Emad your point seems right. I should have included a check for the cam capture before getting into action. I would request you to raise a Pull Request to fix the Issue. I can then merge it in accordingly. Thanks.
