For those of you who use the latest version of gym (0.12.0), the above import will not work.
That is because openai removed it in version 0.11.0: https://github.com/openai/gym
My advice for you is to downgrade gym version to match the version installed on nova, which is 0.10.3.
See tl;dr for suggested way to downgrade.
