问题
I have windows 7 x64 and python 3.4. I try to use cv2 module:
import numpy as np
import cv2
img = cv2.imread('messi5.jpg',0)
As I know, there is no way to use opencv 2 with python 3.4. Therefore, I downloaded opencv 3 beta. But I don't understand how to use this stuff for my purpose. Folder ~\opencv\build\python\ contains python 2.7 folder, but there is not python 3.4 folder.
How to solve my task?
Update (06.06.2015).
OpenCV 3 has been released. You can directly download it from official site.
回答1:
you need to build it from source using cmake. Follow the instructions of standard install procedure link, you will find OPENCVDIR/build/install/python/x64(or86)/3.4/cv.pyd. Copy this file and all the .dll files to the python site-packges dir, I was able to "import cv2"
