MetaDrive: an Open-source Driving Simulator for AI and Autonomy Research

[ Documentation | Colab Examples | Demo Video | Website | Paper | Relevant Projects ]

MetaDrive is a driving simulator with the following key features:

• Compositional: It supports synthesising infinite scenes with various road maps and traffic settings or loading real-world driving logs for the research of generalizable RL.
• Lightweight: It is easy to install and run on Linux/Windows/MacOS with sensor simulation support. It can run up to +1000 FPS on a standard PC.
• Realistic: Accurate physics simulation and multiple sensory input including point cloud, RGB/Depth/Semantic images, top-down semantic map and first-person view images.

🛠 Quick Start

Install MetaDrive via:

git clone https://github.com/metadriverse/metadrive.git
cd metadrive
pip install -e .

You can verify the installation of MetaDrive via running the testing script:

# Go to a folder where no sub-folder calls metadrive
python -m metadrive.examples.profile_metadrive

Note that please do not run the above command in a folder that has a sub-folder called ./metadrive.

🚕 Examples

We provide examples to demonstrate features and basic usages of MetaDrive after the local installation. There is an .ipynb example which can be directly opened in Colab.

Also, you can try examples in the documentation directly in Colab! See more details in Documentations.

Single Agent Environment

Run the following command to launch a simple driving scenario with auto-drive mode on. Press W, A, S, D to drive the vehicle manually.

python -m metadrive.examples.drive_in_single_agent_env

Run the following command to launch a safe driving scenario, which includes more complex obstacles and cost to be yielded.

python -m metadrive.examples.drive_in_safe_metadrive_env

Multi-Agent Environment

You can also launch an instance of Multi-Agent scenario as follows

python -m metadrive.examples.drive_in_multi_agent_env --env roundabout

--env accepts following parmeters: roundabout (default), intersection, tollgate, bottleneck, parkinglot, pgmap. Adding --top_down can launch top-down pygame renderer.

Real Environment

Running the following script enables driving in a scenario constructed from nuScenes dataset or Waymo dataset.

python -m metadrive.examples.drive_in_real_env

The default real-world dataset is nuScenes. Use --waymo to visualize Waymo scenarios. Traffic vehicles can not response to surrounding vchicles if directly replaying them. Add argument --reactive_traffic to use an IDM policy control them and make them reactive. Press key r for loading a new scenario, and b or q for switching perspective.

Basic Usage

To build the RL environment in python script, you can simply code in the Farama Gymnasium format as:

from metadrive.envs.metadrive_env import MetaDriveEnv

env = MetaDriveEnv(config={"use_render": True})
obs, info = env.reset()
for i in range(1000):
    obs, reward, terminated, truncated, info = env.step(env.action_space.sample())
    if terminated or truncated:
        env.reset()
env.close()

🏫 Documentations

Please find more details in: https://metadrive-simulator.readthedocs.io

Running Examples in Doc

The documentation is built with .ipynb so every example can run locally or with colab. For Colab running, on the Colab interface, click “GitHub,” enter the URL of MetaDrive: https://github.com/metadriverse/metadrive, and hit the search icon. After running examples, you are expected to get the same output and visualization results as the documentation!

For example, hitting the following icon opens the source .ipynb file of the documentation section: Environments.
