Hello I'm working on Raspberry Pi with OpenCV. I want to try a tutorial which is ball tracking in link http://www.pyimagesearch.com/2015/09/14/ball-tracking-with-opencv/
But when I compile it, i get an error: 'NoneType' object has no attribute 'shape'.
What should I do?

The Python "AttributeError: 'NoneType' object has no attribute 'shape'" occurs when we access the shape attribute on a None value, e.g. after passing an incorrect path to cv2. imread() . To solve the error, make sure to specify the correct path.
imread. If you are receiving a NoneType error and your code is calling cv2. imread , then the likely cause of the error is an invalid file path supplied to cv2.
It means that somewhere a function which should return a image just returned None and therefore has no shape attribute. Try "print img" to check if your image is None or an actual numpy object.

I faced the same problem today, please check for the path of the image as mentioned by cybseccrypt. After imread, try printing the image and see. If you get a value, it means the file is open.
Code:
img_src = cv2.imread('/home/deepak/python-workout/box2.jpg',0)
print img_src
Hope this helps!
