Dependency: dill

[pedronahum]

Hi,

This is, of course, a minor issue, but managed to make it run (Ubuntu 16.04) after installing "dill."

Best,

Pedro

It also requires the package "mock", so one should "pip install mock dill" before running this.

for Python 3.3+, mock has been merged into unittest, which is a built-in library, no need to install, just
modify

import mock

as

from unittest import mock
