This repository contains a set of competitive multi-agent environments used in the paper Continuous Adaptation via Meta-Learning in Nonstationary and Competitive Environments.

RoboSumo depends on numpy, gym, and mujoco_py>=1.5 (if you haven't used MuJoCo before, please refer to the installation guide). Running demos with pre-trained policies additionally requires tensorflow>=1.1.0 and click.

The requirements can be installed via pip as follows:

$ pip install -r requirements.txt

To install RoboSumo, clone the repository and run pip install:

$ git clone https://github.com/openai/robosumo
$ cd robosumo
$ pip install -e .

You can run demos of the environments using demos/play.py script:

$ python demos/play.py

The script allows you to select different opponents as well as different policy architectures and versions for the agents. For details, please refer to the help:

$ python demos/play.py --help
