I am currently trying to use the Atari module for gym/openai. I have successfully managed to install the dependency.
Patricks-MacBook-Pro:~ patrickmaynard$ python3.6 -m pip install gym[atari]

However, when I try to run the file the compiler cannot find the module and I get the following error:

During handling of the above exception, another exception occurred:

gym and cmake have already been installed.
'atari_py' will not work in my pycharm IDE. Try another IDE or run the file in terminal/command line.
