Install python3.6 & pip3 on MacOS

  1. Install Python 3.6.x from https://www.python.org/downloads/ or via homebrew.
$ brew install python3   # Installed at /usr/local/Cellar/python3

Check that python3 has been installed by running it at the terminal:

$ python3
>>> Python 3.6.5
  1. Download get-pip.py from https://bootstrap.pypa.io/get-pip.py and install (this should already be installed if python was installed from python.org or homebrew):
$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3 get-pip.py
  1. Install virtualenv and virtualenvwrapper
$ sudo -H pip3 install virtualenv
$ sudo -H pip3 install virtualenvwrapper --ignore-installed six
  1. Add the following to your ~/.bash_profile to load virtualenvwrapper then run bash -l
if [ -e /usr/local/bin/virtualenvwrapper.sh ]; then
  source /usr/local/bin/virtualenvwrapper.sh
fi
  1. Create your virtual enviornment named py3
$ mkvirtualenv --python=`which python3.6` py3
/*
* To install all modules: pip3 install -r requirements.txt

Installing opencv3 with python3.6

$ 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'
Install these modules from Github as their py3 support is currently not published on PyPI. Their master branch works with Python3.6

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/[email protected]
$ pip3 install git+git://github.com/statsmodels/statsmodels
$ pip3 install git+git://github.com/pymc-devs/pymc3
$ brew install llvm
$ brew link llvm --force
$ pip3 install numba
