I am trying the following and getting the same error each time:
pip install adspy
pip install adspy-0.2.0.tar.gz
Error:

Complete output from command python setup.py egg_info:

adspy_shared_utilities.py is not a module it is just a file that it is used in "Applied Machine Learning in Python" course in coursera.
I hope it solve this problem.
