$ brew update
$ brew install opencv3 --with-python3 # Add --with-contrib if you want the contrib modules
$ ln -s /usr/local/opt/opencv3/lib/python3.6/site-packages/cv2.cpython-36m-darwin.so /usr/local/lib/python3.6/site-packages/cv2.so
You may have to export PYTHONPATH:
export PYTHONPATH=$PYTHONPATH:/usr/local/Cellar/opencv3/3.4.1_5/lib/python3.6/site-packages
If you installed a previous version of opencv and no longer need it, remove it:
brew cleanup opencv
Test:
$ python3
In[1]: import cv2
In[2]: cv2.__version__
Out[2]: '3.4.1'
Set your locale in an environment variable in ~/.bash_profile
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
Type bash -l in your terimal to run the updated bash_profile.
Now, install the modules:
$ pip3 install git+git://github.com/cython/cython@master
$ pip3 install git+git://github.com/statsmodels/statsmodels
$ pip3 install git+git://github.com/pymc-devs/pymc3
$ brew install llvm
