Introduction

MTRL is a library of multi-task reinforcement learning algorithms. It has two main components:

• Building blocks and agents that implement the multi-task RL algorithms.

• Experiment setups that enable training/evaluation on different setups.

Together, these two components enable use of MTRL across different environments and setups.

Setup

• Clone the repository: git clone [email protected]:facebookresearch/mtrl.git.

• Install dependencies: pip install -r requirements/dev.txt

Usage

• MTRL supports 8 different multi-task RL algorithms as described here.

• MTRL supports multi-task environments using MTEnv. These environments include MetaWorld and multi-task variants of DMControl Suite

• Refer the tutorial to get started with MTRL.

Contributing to MTRL

There are several ways to contribute to MTRL.

1. Use MTRL in your research.

2. Contribute a new algorithm. We currently support 8 multi-task RL algorithms and are looking forward to adding more environments.

3. Check out the good-first-issues on GitHub and contribute to fixing those issues.

4. Check out additional details here.
