I take it that this is python-2.7? code? 

Searching thru the python3 results in synaptic, on a stretch install on 
the rock64, python3 has not a p3 version of numpy or cv2.

And I'd like to try and make it run on 3.5 since that seems to be the 
newest on stretch. That would tend to future-proof this past the final 
fixes and eventual demise of python-2.

Is there hope for things like numpy and cv2 being ported to python 3? Or 
can numpy and cv2 be used against 3.5 as is?

Thanks Oscar.
