Offline Multi-Agent Reinforcement Learning Datasets and Baselines

Going Off-the-Grid! 🤖 ⚡ 🔌 🔋

Offline MARL holds great promise for real-world applications by utilising static datasets to build decentralised controllers of complex multi-agent systems. However, currently offline MARL lacks a standardised benchmark for measuring meaningful research progress. Off-the-Grid MARL (OG-MARL) fills this gap by providing a diverse suite of datasets with baselines on popular MARL benchmark environments in one place, with a unified API and an easy-to-use set of tools.

OG-MARL forms part of the InstaDeep MARL ecosystem, developed jointly with the open-source community. To join us in these efforts, reach out, raise issues or just 🌟 to stay up to date with the latest developments!

Quickstart 🏎️

Clone this repository.

git clone https://github.com/instadeepai/og-marl.git

Install og-marl and its dependencies. We tested og-marl with Python 3.9. Consider using a conda virtual environment.

pip install -e .

pip install flashbax==0.1.2

Download environment dependencies. We will use SMACv1 in this example.

bash install_environments/smacv1.sh

Download a dataset.

python examples/download_dataset.py --env=smac_v1 --scenario=3m

Run a baseline. In this example we will run MAICQ.

python baselines/main.py --env=smac_v1 --scenario=3m --dataset=Good --system=maicq

Dataset API

We provide a simple demonstrative notebook of how to use OG-MARL's dataset API here:

Datasets 🎥

We have generated datasets on a diverse set of popular MARL environments. A list of currently supported environments is included in the table below. It is well known from the single-agent offline RL literature that the quality of experience in offline datasets can play a large role in the final performance of offline RL algorithms. Therefore in OG-MARL, for each environment and scenario, we include a range of dataset distributions including Good, Medium, Poor and Replay datasets in order to benchmark offline MARL algorithms on a range of different dataset qualities. For more information on why we chose to include each environment and its task properties, please read our accompanying paper.

Dataset Backends 🔌

We are in the process of migrating our datasets from TF Records to Flashbax Vaults. Flashbax Vaults have the advantage of being significantly more flexible than the TF Record Datasets.
