RL Baselines3 Zoo: A Training Framework for Stable Baselines3 Reinforcement Learning Agents

RL Baselines3 Zoo is a training framework for Reinforcement Learning (RL), using Stable Baselines3.

It provides scripts for training, evaluating agents, tuning hyperparameters, plotting results and recording videos.

In addition, it includes a collection of tuned hyperparameters for common environments and RL algorithms, and agents trained with those settings.

We are looking for contributors to complete the collection!

Goals of this repository:

1. Provide a simple interface to train and enjoy RL agents
2. Benchmark the different Reinforcement Learning algorithms
3. Provide tuned hyperparameters for each environment and RL algorithm
4. Have fun with the trained agents!

This is the SB3 version of the original SB2 rl-zoo.

Documentation

Documentation is available online: https://rl-baselines3-zoo.readthedocs.io/

Installation

Minimal installation

From source:

pip install -e .

As a python package:

pip install rl_zoo3

Note: you can do python -m rl_zoo3.train from any folder and you have access to rl_zoo3 command line interface, for instance, rl_zoo3 train is equivalent to python train.py

Full installation (with extra envs and test dependencies)

apt-get install swig cmake ffmpeg
pip install -e .[plots,tests,extras]

macOS note: if pybullet fails to build (with errors from stdio.h), retry with:

CFLAGS="-fno-define-target-os-macros" pip install -e .[plots,tests,extras]

Please see Stable Baselines3 documentation for alternatives to install stable baselines3.

Train an Agent

The hyperparameters for each environment are defined in hyperparameters/algo_name.yml.

If the environment exists in this file, then you can train an agent using:

python train.py --algo algo_name --env env_id

Evaluate the agent every 10000 steps using 10 episodes for evaluation (using only one evaluation env):

python train.py --algo sac --env HalfCheetahBulletEnv-v0 --eval-freq 10000 --eval-episodes 10 --n-eval-envs 1

More examples are available in the documentation.

Integrations

The RL Zoo has some integration with other libraries/services like Weights & Biases for experiment tracking or Hugging Face for storing/sharing trained models. You can find out more in the dedicated section of the documentation.

Plot Scripts

Please see the dedicated section of the documentation.

Enjoy a Trained Agent

Note: to download the repo with the trained agents, you must use git clone --recursive https://github.com/DLR-RM/rl-baselines3-zoo in order to clone the submodule too.

If the trained agent exists, then you can see it in action using:

python enjoy.py --algo algo_name --env env_id

For example, enjoy A2C on Breakout during 5000 timesteps:

python enjoy.py --algo a2c --env BreakoutNoFrameskip-v4 --folder rl-trained-agents/ -n 5000

Hyperparameters Tuning

Please see the dedicated section of the documentation.

Custom Configuration

Please see the dedicated section of the documentation.

Current Collection: 200+ Trained Agents!

Final performance of the trained agents can be found in benchmark.md. To compute them, simply run python -m rl_zoo3.benchmark.

List and videos of trained agents can be found on our Huggingface page: https://huggingface.co/sb3

NOTE: this is not a quantitative benchmark as it corresponds to only one run (cf issue #38). This benchmark is meant to check algorithm (maximal) performance, find potential bugs and also allow users to have access to pretrained agents.
