gym-carla

A Gym wrapper for CARLA simulator

System Requirements

• Ubuntu 16.04

Installation

1. Setup conda environment

$ conda create -n env_name python=3.6
$ conda activate env_name

2. Clone this git repo in an appropriate folder

$ git clone https://github.com/cjy1992/gym-carla.git

3. Enter the repo root folder and install the packages:

$ pip install -r requirements.txt
$ pip install -e .

4. Download CARLA_0.9.6, extract it to some folder, and add CARLA to PYTHONPATH environment variable:

$ export PYTHONPATH=$PYTHONPATH:$YourFolder$/CARLA_0.9.6/PythonAPI/carla/dist/carla-0.9.6-py3.5-linux-x86_64.egg

Usage

1. Enter the CARLA root folder and launch the CARLA server by:

$ ./CarlaUE4.sh -windowed -carla-port=2000

You can use Alt+F1 to get back your mouse control.

Or you can run in non-display mode by:

$ DISPLAY= ./CarlaUE4.sh -opengl -carla-port=2000

2. Run the test file:

$ python test.py

See details of test.py about how to use the CARLA gym wrapper.

Description

1. We provide a dictionary observation including front view camera (obs['camera']), birdeye view lidar point cloud (obs['lidar']) and birdeye view semantic representation (obs['birdeye']).

2. The termination condition is either the ego vehicle collides, runs out of lane, reaches a destination, or reaches the maximum episode timesteps. Users may modify function _terminal in carla_env.py to enable customized termination condition.

3. The reward is a weighted combination of longitudinal speed and penalties for collision, exceeding maximum speed, out of lane, large steering and large lateral accleration. Users may modify function _get_reward in carla_env.py to enable customized termination condition.
