Fork of RL Baselines Zoo for SlimeVolleyGym
Note: This is a fork of Baselines Zoo, not the official version, for training agents on Slime Volleyball Environment.
PPO2, ACER, ACKTR, A2C, DQN training for SlimeVolleyNoFrameSkip-v0 are in logs
directory.

RL Baselines Zoo: a Collection of Pre-Trained Reinforcement Learning Agents
A collection of trained Reinforcement Learning (RL) agents, with tuned hyperparameters, using Stable Baselines.
We are looking for contributors to complete the collection!
Goals of this repository:
- Provide a simple interface to train and enjoy RL agents
- Benchmark the different Reinforcement Learning algorithms
- Provide tuned hyperparameters for each environment and RL algorithm
- Have fun with the trained agents!
Enjoy a Trained Agent
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 trained_agents/ -n 5000
If you have trained an agent yourself, you need to do:
# exp-id 0 corresponds to the last experiment, otherwise, you can specify another ID
python enjoy.py --algo algo_name --env env_id -f logs/ --exp-id 0
To load the best model (when using evaluation environment):
python enjoy.py --algo algo_name --env env_id -f logs/ --exp-id 1 --load-best
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
For example (with tensorboard support):
python train.py --algo ppo2 --env CartPole-v1 --tensorboard-log /tmp/stable-baselines/
Evaluate the agent every 10000 steps using 10 episodes for evaluation:
python train.py --algo sac --env HalfCheetahBulletEnv-v0 --eval-freq 10000 --eval-episodes 10
Save a checkpoint of the agent every 100000 steps:
python train.py --algo td3 --env HalfCheetahBulletEnv-v0 --save-freq 100000
Continue training (here, load pretrained agent for Breakout and continue training for 5000 steps):
python train.py --algo a2c --env BreakoutNoFrameskip-v4 -i trained_agents/a2c/BreakoutNoFrameskip-v4.pkl -n 5000
Note: when training TRPO, you have to use mpirun
to enable multiprocessing:
mpirun -n 16 python train.py --algo trpo --env BreakoutNoFrameskip-v4
Hyperparameter Tuning
We use Optuna for optimizing the hyperparameters.
Note: hyperparameters search is not implemented for ACER and DQN for now.
when using SuccessiveHalvingPruner ("halving"), you must specify --n-jobs > 1
Budget of 1000 trials with a maximum of 50000 steps:
python train.py --algo ppo2 --env MountainCar-v0 -n 50000 -optimize --n-trials 1000 --n-jobs 2 \
--sampler tpe --pruner median
Env Wrappers
You can specify in the hyperparameter config one or more wrapper to use around the environment:
for one wrapper:
env_wrapper: gym_minigrid.wrappers.FlatObsWrapper
for multiple, specify a list:
env_wrapper:
- utils.wrappers.DoneOnSuccessWrapper:
reward_offset: 1.0
- utils.wrappers.TimeFeatureWrapper
Note that you can easily specify parameters too.
Env keyword arguments
You can specify keyword arguments to pass to the env constructor in the command line, using --env-kwargs
:
python enjoy.py --algo ppo2 --env MountainCar-v0 --env-kwargs goal_velocity:10
Overwrite hyperparameters
You can easily overwrite hyperparameters in the command line, using --hyperparams
:
python train.py --algo a2c --env MountainCarContinuous-v0 --hyperparams learning_rate:0.001 policy_kwargs:"dict(net_arch=[64, 64])"
Record a Video of a Trained Agent
Record 1000 steps:
python -m utils.record_video --algo ppo2 --env BipedalWalkerHardcore-v2 -n 1000
Current Collection: 120+ Trained Agents!
Scores can be found in benchmark.md
. To compute them, simply run python -m utils.benchmark
.

PyBullet Environments
See https://github.com/bulletphysics/bullet3/tree/master/examples/pybullet/gym/pybullet_envs.
Similar to MuJoCo Envs but with a free simulator: pybullet. We are using BulletEnv-v0
version.
Note: those environments are derived from Roboschool and are much harder than the Mujoco version (see Pybullet issue)

There are 19 environment groups (variations for each) in total.
Note that you need to specify --gym-packages gym_minigrid with enjoy.py and train.py as it is not a standard Gym environment, as well as installing the custom Gym package module or putting it in python path.
pip install gym-minigrid
python train.py --algo ppo2 --env MiniGrid-DoorKey-5x5-v0 --gym-packages gym_minigrid
This does the same thing as:
import gym_minigrid
Also, you may need to specify a Gym environment wrapper in hyperparameters, as MiniGrid environments have Dict observation space, which is not supported by StableBaselines for now.
MiniGrid-DoorKey-5x5-v0:
env_wrapper: gym_minigrid.wrappers.FlatObsWrapper
Colab Notebook: Try it Online!
You can train agents online using colab notebook.
