After all dependencies have been installed I still get the following exception:

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/gym/envs/atari/atari_env.py", line 9, in
import atari_py
ModuleNotFoundError: No module named 'atari_py'

In addition to this I can't find any module in the package named atari_py
I am running on Mac0S and cmake/gym have already been installed.

I suspect the old version of gym[atari] is installed; you could try either python3.6 -m pip install --upgrade gym[atari], or install baselines from scratch in a clean virtualenv.
