Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/zmq/eventloop/ioloop.py", line 330, in start

I had to upgrade pyzmq to get it working:

sudo pip install pyzmq --upgrade

If the problem still persists try upgrading the rest of the libraries which are:

sudo pip install jinja2
sudo pip install tornado

If you don't wanna be messing around with these libraries you could run a virtual environment and install everything there. Here is the documentation: http://docs.python-guide.org/en/latest/dev/virtualenvs/

Hope it helps, cheers!
