Shared compatibility

  • Python · carla: Python runtime · l2r: Python runtime

Choose carla if…

  • carla is primarily C++; l2r is Python.
  • License: carla is MIT, l2r is GPL-2.0.
  • Tags unique to carla: artificial-intelligence, computer-vision, deep-reinforcement-learning, imitation-learning.
  • When your project requires Unreal Engine 5.5 capabilities for realistic simulation of complex autonomous vehicle scenarios

When NOT to use carla

  • If your project or research does not require the advanced features of Unreal Engine 5.5 and you are constrained by older hardware or software like Windows 10 or Ubuntu 20.04
  • When your immediate focus is on rapid deployment rather than simulation, as setting up CARLA requires significant setup time due to its system requirements
  • If your project focuses on non-autonomous driving applications where the specialized assets and simulations of CARLA may not be directly applicable

Choose l2r if…

  • l2r is primarily Python; carla is C++.
  • License: l2r is GPL-2.0, carla is MIT.
  • Requirements: Requires Docker; Requires Python 3.8 or higher; Nvidia graphics card and associated drives are necessary, with minimum recommendation of an Nvidia 970 GTX for simulator operation; Installation assumes a Linux operating system. For non-Linux environments, a public cloud instance with GPU is suggested.
  • Tags unique to l2r: arrival-simulator, reinforcement-learning.
  • l2r ships Docker support for self-hosted deployment.
  • When your project includes developing AI systems for autonomous vehicle simulation with a focus on racing environments

When NOT to use l2r

  • When your project does not involve autonomous driving or is not specifically focused on the simulation of racing scenarios
  • For those who cannot meet the hardware requirements, such as lacking a suitable Nvidia GPU for running the simulator
  • If you are working in an OS environment that is not Linux, given that proper support and installation steps target Linux systems
