I refered to this link. But it did not help me.

I installed python 2.7 and opencv 3.2.0. cv2.pyd exist in the Python34\Lib\site-packages folder. When i run the following code

import cv2

Python shows the above error.

Help me! Thank for supporting!

Are you limited in using 3.2.0? If no I suggest to try prebuilt wheels: http://www.lfd.uci.edu/~gohlke/python...

@electron: No. I build opencv 3.2.0 normal. Not limit.

download wheel and install it using pip: pip install path_to_wheel

btw, seems that you are trying to use in Python37 opencv installed for Python34. Check if you're using correct python versin and make sure that python is in PATH

I solved it. My solution is: - Copied all "dll" libraries from release folder to "C:\Python27"

Python 3.X or Anaconda users, use the below in the prompt <pip install="" opencv-python="">
