A Pytorch implementation of the multi agent deep deterministic policy gradients(MADDPG) algorithm

This is my implementation of the algorithm presented in the paper: Multi Agent Actor Critic for Mixed Cooperative-Competitive Environments. You can find this paper here: https://arxiv.org/pdf/1706.02275.pdf

You will need to install the Multi Agent Particle Environment(MAPE), which you can find here: https://github.com/openai/multiagent-particle-envs

Make sure to create a virtual environment with the dependencies for the MAPE, since they are somewhat out of date. I also recommend running this with PyTorch version 1.4.0, as the latest version (1.8) seems to have an issue with an in place operation I use in the calculation of the critic loss.

It's probably easiest to just clone this repo into the same directory as the MAPE, as the main file requires the make_env function from that package.
