Python-sql, using documented example but get 'No module named 'sql.aggregate' error

Question

I want to use python-sql as per this link. python-sql project home. I install sql using "pip install sql", and it goes as planned. However, when I place the import at the top of my module;

from sql import *
from sql.aggregate import *
from sql.conditional import *

PyCharm indicates that sql.aggregate could not be resolved. If I try to execute the code, I get an error

ImportError: No module named 'sql.aggregate'; 'sql' is not a package

I've done a lot of searching on it and can't find what I am doing wrong. I'm a Python newbe, so I hope it is something simple - but I couldn't find anything in the docs about installation.

You need to install python-sql, not sql:

pip install python-sql

sql is a different project altogether.
