beginner problem happened to me, it is that try to run the program line by line in the interpreter, and the variable image was None type, I now you already know that, but I write just in case (opencv 3.0 and python 2.7 in ubuntu 14.04)

Do you have higher quality videos? I can hear what you say but I can not see what you do. The text is blurred.

Hello, the problem in my case is:
init done
opengl support available
Traceback (most recent call last):
  File "1.py", line 8, in <module>
    h, w = image.shape[:2]
AttributeError: 'NoneType' object has no attribute 'shape'
