This is a list of Gym environments, including those packaged with Gym, official OpenAI environments, and third party environment.
For information on creating your own environment, see Creating your own Environment.
The code for each environment group is housed in its own subdirectory gym/envs. The specification of each task is in gym/envs/__init__.py. It's worth browsing through both.
These are a variety of algorithmic tasks, such as learning to copy a sequence.
import gym
env = gym.make('Copy-v0')
env.reset()
env.render()The Atari environments are a variety of Atari video games. If you didn't
do the full install, you can install dependencies via pip install -e '.[atari]' (you'll need cmake installed) and then get started as
follows:
import gym
env = gym.make('SpaceInvaders-v0')
env.reset()
env.render()This will install atari-py, which automatically compiles the Arcade
Learning Environment. This
can take quite a while (a few minutes on a decent laptop), so just be
prepared.
Box2d is a 2D physics engine. You can install it via pip install -e '.[box2d]' and then get started as follows:
import gym
env = gym.make('LunarLander-v2')
env.reset()
env.render()These are a variety of classic control tasks, which would appear in a
typical reinforcement learning textbook. If you didn't do the full
install, you will need to run pip install -e '.[classic_control]' to
enable rendering. You can get started with them via:
import gym
env = gym.make('CartPole-v0')
env.reset()
env.render()MuJoCo is a physics engine which can do very
detailed efficient simulations with contacts. It's not open-source, so
you'll have to follow the instructions in
mujoco-py
to set it up. You'll have to also run pip install -e '.[mujoco]' if
you didn't do the full install.
import gym
env = gym.make('Humanoid-v2')
env.reset()
env.render()These environments also use MuJoCo. You'll have to also run pip install -e '.[robotics]' if
you didn't do the full install.
import gym
env = gym.make('HandManipulateBlock-v0')
env.reset()
env.render()You can also find additional details in the accompanying technical report and blog post. If you use these environments, you can cite them as follows:
@misc{1802.09464,
Author = {Matthias Plappert and Marcin Andrychowicz and Alex Ray and Bob McGrew and Bowen Baker and Glenn Powell and Jonas Schneider and Josh Tobin and Maciek Chociej and Peter Welinder and Vikash Kumar and Wojciech Zaremba},
Title = {Multi-Goal Reinforcement Learning: Challenging Robotics Environments and Request for Research},

Eprint = {arXiv:1802.09464},
}
Toy environments which are text-based. There's no extra dependency to install, so to get started, you can just do:
import gym
env = gym.make('FrozenLake-v0')
env.reset()
env.render()16 simple-to-use procedurally-generated gym environments which provide a direct measure of how quickly a reinforcement learning agent learns generalizable skills. The environments run at high speed (thousands of steps per second) on a single core.

Gym Retro lets you turn classic video games into Gym environments for reinforcement learning and comes with integrations for ~1000 games. It uses various emulators that support the Libretro API, making it fairly easy to add new emulators.

We recommend using the PyBullet Robotics Environments instead
3D physics environments like Mujoco environments but uses the Bullet physics engine and does not require a commercial license.

The gym comes prepackaged with many many environments. It's this common API around many environments that makes Gym so great. Here we will list additional environments that do not come prepacked with the gym. Submit another to this list via a pull-request.
3D physics environments like the Mujoco environments but uses the Bullet physics engine and does not require a commercial license. Works on Mac/Linux/Windows.

Platforms: Windows, Mac, Linux
PGE is a FOSS 3D engine for AI simulations, and can interoperate with the Gym. Contains environments with modern 3D graphics, and uses Bullet for physics.

MiniWorld is a minimalistic 3D interior environment simulator for reinforcement learning & robotics research. It can be used to simulate environments with rooms, doors, hallways and various objects (eg: office and home environments, mazes). MiniWorld can be seen as an alternative to VizDoom or DMLab. It is written 100% in Python and designed to be easily modified or extended.

The environment consists of transportation puzzles in which the player's goal is to push all boxes on the warehouse's storage locations. The advantage of the environment is that it generates a new random level every time it is initialized or reset, which prevents over fitting to predefined levels.

The environment is fully-compatible with the OpenAI baselines and exposes a NAS environment following the Neural Structure Code of BlockQNN: Efficient Block-wise Neural Network Architecture Generation. Under this setting, a Neural Network (i.e. the state for the reinforcement learning agent) is modeled as a list of NSCs, an action is the addition of a layer to the network, and the reward is the accuracy after the early-stop training. The datasets considered so far are the CIFAR-10 dataset (available by default) and the meta-dataset (has to be manually downloaded as specified in this repository).

An environment for behavioural planning in autonomous driving, with an emphasis on high-level perception and decision rather than low-level sensing and control. The difficulty of the task lies in understanding the social interactions with other drivers, whose behaviours are uncertain. Several scenes are proposed, such as highway, merge, intersection and roundabout.
