Overview


MetaDrive: Composing Diverse Driving Scenarios for Generalizable RL


MetaDrive is a driving simulator with the following key features:

  • Compositional: It supports generating infinite scenes with various road maps and traffic settings for the research of generalizable RL.
  • Lightweight: It is easy to install and run. It can run up to 300 FPS on a standard PC.
  • Realistic: Accurate physics simulation and multiple sensory input including Lidar, RGB images, top-down semantic map and first-person view images.

🛠 Quick Start

Install MetaDrive via:

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

or

pip install metadrive-simulator

Note that the program is tested on both Linux and Windows. Some control and display issues in MacOS wait to be solved

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

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

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

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

or launch and render in pygame front end

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

env argument could be:

  • roundabout (default)
  • intersection
  • tollgate
  • bottleneck
  • parkinglot
  • pgmap

Run the example of procedural generation of a new map as:

python -m metadrive.examples.procedural_generation

Note that the above four scripts can not be ran in a headless machine. Please refer to the installation guideline in documentation for more information about how to launch runing in a headless machine.

Run the following command to draw the generated maps from procedural generation:

python -m metadrive.examples.draw_maps

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

import metadrive  # Import this package to register the environment!
import gym

env = gym.make("MetaDrive-v0", config=dict(use_render=True))
# env = metadrive.MetaDriveEnv(config=dict(environment_num=100))  # Or build environment from class
env.reset()
for i in range(1000):
    obs, reward, done, info = env.step(env.action_space.sample())  # Use random policy
    env.render()
    if done:
        env.reset()
env.close()

  • Reproducibility Problem

    Reproducibility Problem

    Hello,

    I am trying to create custom scenarios. For that, I created a custom map similar to vis_a_small_town.py, and I am using the drive_in_multi_agent_env.py example. The environment is defined as follow:

    env = envs[env_cls_name](
        {
            "use_render": True, # if not args.pygame_render else False,
            "manual_control": True,
            "crash_done": False,
            #"agent_policy": ManualControllableIDMPolicy, 
            "num_agents": total_agent_number,
            #"prefer_track_agent": "agent3",
            "show_fps": True, 
            "vehicle_config": {
                "lidar": {"num_others": total_agent_number},
                "show_lidar": False,    
            },
            "target_vehicle_configs": {"agent{}".format(i): {
                    #"spawn_lateral": i * 2,
                    "spawn_longitude": i * 10,
                    #"spawn_lane_index":0,
                    "vehicle_model": vehicle_model_list[i],
                    #"max_engine_force":1,
                    "max_speed":100,
                }
                                           for i in range(5)}
        }
    )

    I have a list that consists of steering and throttle_brake values. The scenario consists of almost 1600 steps. I am assigning these values regarding step number into env.step:

    o, r, d, info=env.step({
                'agent0': [agent0.steering, agent0.pedal], 
                'agent1': [agent1.steering, agent1.pedal],
                'agent2': [agent2.steering, agent2.pedal],
                'agent3': [agent3.steering, agent3.pedal],
                'agent4': [agent4.steering, agent4.pedal],
                'agent5': [agent5.steering, agent5.pedal],
                'agent6': [agent6.steering, agent6.pedal],
                'agent7': [agent7.steering, agent7.pedal],
                'agent8': [agent8.steering, agent8.pedal],
                'agent9': [agent9.steering, agent9.pedal],
                }
            )

    At the end of the list for vehicle commands, the counter for loop set the zero, and commands are reused. Also, vehicles' locations, speeds, and headings are set to initial values stored in the dictionary:

    def initilize_vehicles(env):

    global total_agent_number

    for i in range (total_agent_number):
        agent_str = "agent" + str(i)
        env.vehicles[agent_str].set_heading_theta(vehicles_initial_values[agent_str]['initial_heading_theta'])
        env.vehicles[agent_str].set_position([vehicles_initial_values[agent_str]['initial_position_x'],vehicles_initial_values[agent_str]['initial_position_y']]) # it is x,y from the first block of the map
        env.vehicles[agent_str].set_velocity(env.vehicles[agent_str].velocity_direction, vehicles_initial_values[agent_str]['initial_velocity'])

    I want to reproduce the scenario and test my main algorithm. However, the problem is vehicles do not act in the same way in every run of scenario. I checked my commands for vehicle using:

    env.vehicles["agent0"].steering,env.vehicles["agent0"].throttle_brake

    Vehicle commands are the same for each repetition of scenarios.

    When I don't use a loop and start the MetaDrive from the terminal, I mostly see the same action from cars. I tested almost 10 times. But in loop case, cars start to act differently after the first loop.

    Reproducibility is a huge concern for me. Is it something about the physic engine? Are there any configuration parameters for the engine?

    Thanks!!

  • RGB Camera returns time-buffered grayscale images

    RGB Camera returns time-buffered grayscale images

    Hi, I am running a vanilla MetaDriveEnv with the rgb camera sensor.

    veh_config = dict(
    image_source="rgb_camera",
    rgb_camera=(IMG_DIM, IMG_DIM))

    I wanted to see the images the sensor was producing, so was saving a few of them: I am using: from PIL import Image

    action = np.array([0,0])
obs, reward, done, info = env.step(action)
img = Image.fromarray(np.array(obs['image']*256,np.uint8))
img.save(f"test.jpeg")

    I noticed that the images all looked grayscale. And upon further inspection I found the following behavior:: Suppose we want (N,N) images, which should be represented as arrays of size (N,N,3). Step 0: image[:,:,0] = zeros(N,N) ; image[:,:,1] = zeros(N,N) ; image[:,:,2] = zeros(N,N) Step 1: image[:,:,0] = zeros(N,N) ; image[:,:,1] = zeros(N,N) ; image[:,:,2] = m1 Step 2: image[:,:,0] = zeros(N,N) ; image[:,:,1] = m1 ; image[:,:,2] = m2 Step 3: image[:,:,0] = m1 ; image[:,:,1] = m2 ; image[:,:,2] = m3

    where m1, m2, m3 are (N,N) matrices.

    So, the images are in reality displaying 3 different timesteps with the color channels taking the time info (R=t-2, G=t-1, B=t) . That is why the images look mostly gray, since the values are identical almost everywhere – except where we expect some movement (contours) where we see that lines look colorful and strange.

    Apologies if this is expected behavior, and I just had some configuration incorrect.

    What is the proper buffer size / batch size / entropy coefficient for SAC to reproduce the results? I find it hard to reproduce results in SafeMetaDriveEnv. In https://arxiv.org/pdf/2109.12674.pdf, does the reported success rate of SAÇ in Table1 refer to the training success rate (and no collision, i.e. safe_rl_env=True)?

  • Suggestion to run multiple instance in parallel?

    Suggestion to run multiple instance in parallel?

    First of all I would like to express my gratitude on this great project. I really like the feature-rich and lightweight nature of MetaDrive as a driving simulator for reinforcement learning.

    I am wondering what is the recommended way to run multiple MetaDrive instances in parallel (each one with a single ego-car agent)? This seem to be a common use case for reinforcement learning training. I am currently running a batch of MetaDrive simulator with each of them in wrapped in a process, which does seem to have overheads of extra resource and communication/synchronization.

    Another problem I encountered when running multiple instances (say, 60 instances on single machine) in their own process is that I will get a lot of warning like this:

    ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection terminated

    I guess this has something to do with audio. This happens even though I am running the TopDown environment, which should not involve sound. Did you see those warning when running multiple instances as well?

    Also, is there a plan to have a vectorized batch version?

    Thanks!
