Import error in Raspberry PI 3

edit

Hi, I have installed OpenCV and python using the following tutorial in my raspberry pi 3 https://www.pyimagesearch.com/2017/09...

it have now two versions of python 1) 2.7.13 (default) 2) 3.5.3

when I am trying to import CV2 in python 3.5.3 it shows error but no error while running the same in python 2.7.13

can any one help me in resolving this ???
