I am trying to install openai gym on a fresh Ubuntu 16VM. I'm following the documentation to install the Atari package, but I keep running into problems:
When I run ipython > v2.7.12
>import gym
>gym.make('SpaceInvaders-v0')
I get :
....
TypeError: super() takes at least 1 argument (0 given)
It seems to run python3 code, however, during the installation I used the default settings. When I run
python3 > 3.5.2
> import gym
ImportError: No module named 'gym'
What am I doing wrong? I installed gym into the user environment with pip --user parameters.
Solution:
Simple fix to use pip3 which is unfortunately not mentioned in the Readme :(
To install to a Python3 environment use the following command
pip3 --user
For debugging between Python2 and Python3 pip environments the following commands are often useful:
pip3 --version
pip --version
It prints out the corresponding Python environment that it is attached to
