I think this is because you imported 'find_packages' as a separate module (using 'from setuptools import...') but in line 15 you try to call it with setuptools.find_packages(). I deleted 'setuptools.' from this line and it solved the error.
However, it failed later with a 'Permission denied' error. This was solved by running the install command as sudo.

Setup.py returned error in line 15:
NameError: name 'setuptools' is not defined.
