I have the same problem! I only need Atari environment but I don't know how to install it...

Use python 3, do not use python2

[pzhokhov]

As @qingzhouzhen pointed out, you need to use python3 (specifically, I have tested it with python3.5 and 3.6). For general package sanity, we recommend using a virtualenv (this will also prevent conflicts between python2 and 3 if you are mainly using former on your machine).

To create and activate the virtualenv, run the following commands:

    pip install virutalenv
    virtualenv env --python=python3 
    . env/bin/activate

Whether python3 is being used in a current env can be tested by running python --version
After that, pip install -e . should succeed, and the installation can be tested using pytest runner as follows:

    pip install pytest
    pytest

Common installation problems include missing cmake, openmpi or (for ubuntu) zlib.
On mac os those can be installed via homebrew (https://brew.sh/) as follows:

    brew install cmake openmpi

On ubuntu:

    apt-get update && apt-get install cmake libopenmpi-dev zlib1g-dev

We'll include these instructions in the README as well.

I have a fork for python2 with tests passing here, but its ugly (I.e. forcing named arguments). I will keep it in-sync for a little while, but as python2.7 is EOL anyway its not worth doing a PR.
