Easiest way

$ sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

This will install scipy together with other packages on python that run on the system. If you're using pyenv, it won't work though because it couldn't find the packages.

This document contains some notes I have gathered while I was trying to setup a redis service using boot2docker running on OS X. This won't cover what Docker is, see Docker website for details.

Installing boot2docker

First, install Virtualbox and follow the steps at http://docs.docker.com/installation/mac/

Since Docker only runs on Linux, boot2docker runs a virtual machine in Virtualbox (or VMWare etc), however you can run the docker command on OS X
