Installing OpenCV 3.1 on OS X El Capitan using Python 3.5.1

I have looked for a proper way to install OpenCV, but all I can find are people fudging around with Python 2.old or virtualenv or other things that are utterly irrelevant. I just want be able to run import cv2 without any import errors.

How do I install OpenCV on OS X 10.11 for use with Python 3.5.1?

For me the only working way was using conda:

conda install --channel https://conda.anaconda.org/menpo opencv3

and then import it using import cv2

We can install opencv3 for Python3(Python3.5) for Mac OS X with homebrew.

First, install homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

You can see the details for how to install homebrew. http://brew.sh

If you don't install Python3, install python3:

brew install python3

Then install opencv3 for python3:

brew install opencv3 --with-python3

Finally, maybe you will link site-packages of opencv3 to the site-packages of Python3:

In the follow command, /usr/local/opt/opencv3/lib/python3.5/site-packages is the directory of opencv3's site-packages, /usr/local/lib/python3.5/site-packages/ is the directory of Python3.5's site-packages. Maybe you should change the two to your own directories.

echo /usr/local/opt/opencv3/lib/python3.5/site-packages >> /usr/local/lib/python3.5/site-packages/opencv3.pth

For mac, i would suggest using homebrew (http://brew.sh), the best package manager for osx; after you install it, you can simply use -from a terminal-:

brew search xxx

To search for a package 'xxx'; in this case, try brew search opencv and you will get the results opencv and opencv3, then just install opencv3 with:

brew install opencv3

And that's it, it will install all the required dependencies (which are listed if you use brew info opencv3).

Any question, just ask.
