Minigrid contains simple and easily configurable grid world environments to conduct Reinforcement Learning research. This library was previously known as gym-minigrid.

This library contains a collection of 2D grid-world environments with goal-oriented tasks. The agent in these environments is a triangle-like agent with a discrete action space. The tasks involve solving different maze maps and interacting with different objects such as doors, keys, or boxes. The design of the library is meant to be simple, fast, and easily customizable.
In addition, the environments found in the BabyAI repository have been included in Minigrid and will be further maintained under this library.
The Gymnasium interface allows to initialize and interact with the Minigrid default environments as follows:
import gymnasium as gym
env = gym.make("MiniGrid-Empty-5x5-v0", render_mode="human")
observation, info = env.reset(seed=42)
for _ in range(1000):
action = policy(observation) # User-defined policy function
observation, reward, terminated, truncated, info = env.step(action)
if terminated or truncated:
observation, info = env.reset()
env.close()
