Install Opencv-python__python under Mac

Under the Mac installation Opencv-python and Windows, the feeling is similar, here the main record of the Mac under the Opencv-python installation process.

_________________________________________________________________________________

1. If there is no homebrew, it is necessary to install first (homebrew similar to Linux Apt-get, for package management, strongly recommended. ）

Address: http://brew.sh/

2. After the homebrew, we'll talk.

Brew tap homebrew/science
Brew Install OpenCV

Note: Because we often use brew's main package, we need to download the brew's sub package, such as Homebrew/science, and then install OPENCV when it comes to some less common packages. You can view additional child packages on the https://github.com/Homebrew.
3. Into the site-packages directory of Python

cd/library/python/2.7/site-packages/

4. Make soft link (download good OpenCV put in/usr/local/cellar/opencv/2.4.12_2/)

Ln-s/usr/local/cellar/opencv/2.4.12_2/lib/python2.7/site-packages/cv.py cv.py
ln-s/usr/local/Cellar/opencv/ 2.4.12_2/lib/python2.7/site-packages/cv2.so cv2.so

5. Configure environment variables (if not previously configured)

Export pythonpath= $PYTHONPATH:/usr/local/lib/python2.7/site-packages

_________________________________________________________________________________
Get. Now you can go to the console and go into the Python interactive mode >>>import cv2 >>> should not complain.
