parking-env

Parking-env is a gymnasium-based environment for reinforcement learning, written in a single Python file and accelerated by Numba. The environment is designed to simulate the task of parking a vehicle in a parking lot, where the agent controls the steering angle and the speed to park the vehicle successfully.

PPO agent with discrete actions

PPO agent with multidiscrete actions

PPO agent with continuous actions

Installation

To install the stable version,

pip install parking-env

To install the current version with additional scripts in editable mode,

git clone https://github.com/KexianShen/parking-env.git
cd parking-env
pip install -e .

Usage

Pre-trained models are uploaded to Hugging Face Hub with detailed notes.

To use parking-env, you can code as follows:

import gymnasium as gym

env = gym.make(
    "Parking-v0", render_mode="human", observation_type="vector", action_type="discrete"
)

env.reset()
terminated = False
truncated = False

while not terminated and not truncated:
    action = 2
    obs, reward, terminated, truncated, info = env.step(action)

Credits

Parking-env is heavily inspired by the HighwayEnv environment, and some of its code was adapted for use in parking-env.

Additionally, parking-env uses the algorithms provided in CleanRL, a collection of clean implementations of popular RL algorithms.
