I enable to integrate opencv with python.I am facing this error in Python shell "RuntimeError: module compiled against API version 0xa but this version of numpy is 0x7 Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> import cv2 ImportError: numpy.core.multiarray failed to import".To resolve this error I try "python -m pip install --upgrade numpy".But this shows invalid syntax.How to resolve this?

It's not working for my computer. Is it a 2.7 version only cause my Python 3.4 is saying "ImportError: Module use of python27.dll conflicts with this version of Python."

Hey! It worked well, but could I also follow the same guide for python 3.5.2? I intend using tensorflow and tf only works with python 3.5.x. Any suggestions around this?
