Python Opencv Mac Os

Python openCV on Mac OS

Install openCV with brew:

$ brew tap homebrew/science
$ brew install opencv

After brew is done installing you might get this warning:

==> Caveats Python modules have been installed and Homebrew's site-packages is not in your Python sys.path, so you will not be able to import the modules this formula installed. If you plan to develop with these modules, please run: mkdir -p ~/Library/Python/2.7/lib/python/site-packages echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth

Just follow the instructions and type the tow commands provided.

$  mkdir -p ~/Library/Python/2.7/lib/python/site-packages

$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth

You should be ready to try importing cv on a python repl window.

$ python
...
>>> import cv
>>>

If something went wrong you should get an error telling you that the cv module was not found.
