Multiple Python installations on OS X

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

Installing Tensorflow on Pycharm (Mac)
  • In Pycharm, Preferences -> Project Interpreter -> Create VirtualEnv -> <your_virtualenv_name_and_location>, and select "inherit global site-packages" option -> OK.
  • In command line, install tensorflow in the virtualenv location you created in previous step. For the above case, let's assume the location is ~/tensorflow_pycharm, therefore, run command virtualenv --system-site-packages -p python3 ~/tensorflow_pycharm or python3 -m venv ~/tensorflow_pycharm(changed in version 3.5: the use of venv is now recommended for creating virtual environments).
  • Install tensorflow with one of the following approaches:
    • From command line
      • Activate the virtualenv environment by issuing one of the following commands: source ~/tensorflow_pycharm/bin/activate
      • Issue the following command to install TensorFlow and all the packages that TensorFlow requires into the active Virtualenv environment: pip3 install --upgrade tensorflow.
      • In PyCharm, select the configured Project Interpreter at `~/t

Python3 Virtualenv Setup

Requirements
  • Python 3
  • Pip 3
$ brew install python3
