Standalone environment version

• Find gym-starcraft at this repository: apsdehal/gym-starcraft
• Find ic3net-envs at this repository: apsdehal/ic3net-envs

Installation

This repository has been tested (to a limited extend, without gym-starcraft) with Python version 3.8.15.

First, clone the repo and install ic3net-envs which contains implementation for Predator-Prey and Traffic-Junction

git clone https://github.com/IC3Net/IC3Net
cd IC3Net/ic3net-envs
python setup.py develop

Optional: If you want to run experiments on StarCraft, install the gym-starcraft package included in this package. Follow the instructions provided in README inside that packages.

Next, we need to install dependencies for IC3Net including PyTorch. For doing that run:

pip install -r requirements.txt

Running

Once everything is installed, we can run the using these example commands

Note: We performed our experiments on nprocesses set to 16, you can change it according to your machine, but the plots may vary.

Note: Use OMP_NUM_THREADS=1 to limit the number of threads spawned
