py_examples error

[burakipekk]

Hi Everyone
I am getting error like below , could you please help me? Camera light is on and I installed OPENCV that was explained in 'http://milq.github.io/install-opencv-ubuntu-debian/' with OPTION 2. All examples work fine but I am still getting error like below. (ValueError: cannot reshape array of size 16922 into shape (7,7,2,4) this line looks like in trouble but I dont know how I can solve.)
