Prepare py3 for probabilistic programming

Python3 environment for running code from Probabilistic Programming
Note that the latter is written using py2.7 but I want to update the code for py3.4

apt-get install apache2-dev
conda create --name phack python=3.4 \
  ipython ipython-notebook matplotlib \
  numpy pymc pyzmq scipy tornado jinja2

# praw and wsgiref not available via anaconda (the latter because the py3.4 version is called mod_wsgi)
source activate phack
pip install praw
pip install mod_wsgi # may be some differences with py2.7/wsgiref

# ipython check that they're all installed:
In [1]: import matplotlib
In [2]: import numpy
In [3]: import pymc
In [4]: import zmq
In [5]: import scipy
In [6]: import tornado
In [7]: import wsgiref
In [8]: import praw
In [9]: import jinja2
# nb, import 'zmq' and 'wsgiref' rather than 'pyzmq' and 'mod_wsgi'
