CARLA Simulator

Build Status Documentation download documentation forum discord

CARLA is an open-source simulator for autonomous driving research. CARLA has been developed from the ground up to support development, training, and validation of autonomous driving systems. In addition to open-source code and protocols, CARLA provides open digital assets (urban layouts, buildings, vehicles) that were created for this purpose and can be used freely. The simulation platform supports flexible specification of sensor suites and environmental conditions.


If you want to benchmark your model in the same conditions as in our CoRL’17 paper, check out Benchmarking.

Building CARLA

Use git clone or download the project from this page. Note that the master branch contains the most recent release of CARLA with the latest fixes and features.

Then follow the instruction at How to build on Linux or How to build on Windows.
The Linux build needs for an UE patch to solve some visualization issues regarding Vulkan. Those already working with a Linux build should install the patch and make the UE build again using the following commands.

# Download and install the UE patch  
cd ~/UnrealEngine_4.24
wget ~/430667-13636743-patch.txt
patch --strip=4 < ~/430667-13636743-patch.txt
# Build UE
./ && ./ && make

Unfortunately we don't have official instructions to build on Mac yet, please check the progress at issue #150.
