Welcome to the world of Mava, a powerful framework designed for simplifying the process of implementing and experimenting with multi-agent reinforcement learning (MARL) algorithms. Developed by the InstaDeep research team, Mava leverages JAX’s capabilities for efficient parallelization, making it easier than ever to iterate on your ideas. This guide will help you get started and ensure a smooth setup experience.

Installation

To use Mava, it’s recommended to clone the repository and perform an editable install. Here’s how you can do it:

git clone https://github.com/instadeepai/mava.git
cd mava
pip install -e .

Mava is compatible with Python versions 3.11 and 3.12, but earlier versions might still work. Please ensure to install the correct version of JAX based on your hardware accelerator. Check the official installation guide for more information on this.

Quickstart Guide

After installing Mava, you can begin training your first model by running one of the system files. For instance:

python mava/systems/ff_ippo.py

Mava utilizes Hydra for configuration management, allowing you to easily modify settings either through YAML files or directly from the terminal. You can specify various environments by adjusting the command line parameters:

python mava/systems/ff_ippo.py env=lbf

Building Blocks of Mava

Mava provides several important features for MARL research:

• Implementations of MARL Algorithms: Including both Centralised Training with Decentralised Execution (CTDE) and Decentralised Training with Decentralised Execution (DTDE) methods.
• Environment Wrappers: Compatible wrappers for integrating with Jumanji environments.
• Educational Material: Quickstart notebooks to help you get a grip on using Mava and highlight JAX’s advantages.
• Statistically Robust Evaluation: Native logging to JSON files to facilitate downstream evaluations.

Performance Insights

One of the standout features of Mava is its performance in executing various tasks. Think of Mava like a high-speed train—optimized to carry passengers (data) quickly and efficiently across different geographical locations (environments). By leveraging its advanced architecture, Mava allows you to train multiple agents simultaneously, thus speeding up the learning process significantly.

Troubleshooting

If you encounter issues during installation or execution, here are some troubleshooting tips:

• Ensure that you have the correct version of Python installed.
• Double-check that you’ve installed JAX as per your hardware requirements from its official guide.
• Look for any issues in the Mava GitHub repository. You can raise an issue if you don’t find a solution.
