opencv和python都已经装好了，可是import报错

Answer 1

I wrote this down before so as not to forget.

Unzip the downloaded opencv compressed package

Goto opencv/build/python/2.7 folder.
Copy cv2.pyd to Anaconda site-packages directory, e.g., D:/Anaconda/Lib/site-packages

Open Python IDLE and type following codes in Python terminal.

import cv2
print cv2.__version__
