Installing on Ubuntu 16.04.1

[scottsisco]

Hi,

I can not get the zen library to install on a fresh install of Ubuntu 16.04.1.

sudo apt-get install git
sudo apt-get install build-essential
sudo apt-get install python-dev
sudo apt-get install virtualenv

I have used the following instructions, but have not made it very far.

git clone https://github.com/networkdynamics/zenlib.git
virtualenv --distribute zenlibenv
source zenlibenv/bin/activate
(zenlibenv) pip install cython
(zenlibenv) pip install numpy
(zenlibenv) cd zenlib/src/
(zenlibenv) python setup.py install

I then test the install with

python -m zen.test

And receive the following following message

/home/scott/zen/zenlibenv/bin/python: No module named matplotlib
/home/scott/zen/zenlibenv/bin/python: No module named networkx

So I run

pip install matplotlib
pip install networkx

I then run the test again.

python -m zen.test

And I am met with the following errors.
