Welcome to the world of autonomous racing! Learn-to-Race is an innovative, multimodal control environment developed to allow agents to learn how to race effectively. It is compliant with OpenAI’s gym and leverages high-fidelity racing simulations, making it a powerful tool for both researchers and enthusiasts in AI and robotics. Here’s how you can get started with Learn-to-Race.

Understanding the Environment

Before we dive into installation and implementation, let’s use an analogy to understand how Learn-to-Race operates. Think of Learn-to-Race like a training camp for Formula 1 drivers. In this camp, each driver (agent) practices on different tracks (training racetracks) before taking the big test on an unknown track (evaluation track) to assess their skills. Additionally, just like a driver has a variety of sensors to gauge their surroundings (like speedometers and rear-view mirrors), agents in Learn-to-Race can use customizable sensors to enhance their performance.

Requirements

• Python: Ensure you have Python version 3.8 or higher.
• Graphics Hardware: You need at least an Nvidia 970 GTX graphics card.
• Docker: This setup uses Docker for environment management.
• Container GPU Access: If you’re running the simulator in a container, ensure it has GPU access via nvidia-container-runtime.

Installation Process

Since Learn-to-Race is designed to run on a Linux OS, follow these steps carefully:

1. Request access to the Racing simulator through this link.
2. You need to decide between two ways to run the simulator:
   • Running as a Python subprocess by specifying the path in your configuration file.
   • Or running as a Docker container by loading the Docker image using:

     bash
     $ docker load < arrival-sim-image.tar.gz
     

3. Download the source code and install the package requirements. Using a virtual environment is highly recommended:

   bash
   $ conda create -n l2r python=3.6
   $ conda activate l2r
   $ pip3 install git+https://github.com/learn-to-race/l2r.git@aicrowd-environment
   

Using Learn-to-Race

Once you have Learn-to-Race set up, you can start creating baseline agents like the RandomActionAgent or the Soft Actor-Critic agent trained over multiple episodes. These agents can be used to explore how different control strategies impact performance on the racetrack.

Troubleshooting Common Issues

Here are some common issues you might encounter along the way, along with their solutions:

• Installation Errors: Ensure you have all dependencies installed. If using Docker, confirm that your Nvidia drivers are updated.
• Performance Issues: If the simulator runs slowly, check that your GPU drivers are up to date and that Docker has access to the GPU.
• Sensor Configuration Problems: Make sure the parameters for your sensors are set correctly in the configuration file. Refer to the documentation for examples.
