Introduction

Welcome to the fascinating world of autonomous driving with the revolutionary project titled Learning to Drive from a World on Rails. In this article, we will take a deep dive into getting started with this project, training and evaluating agents, and troubleshooting common issues. Let’s buckle up and get rolling!

Getting Started

Before you set off on this journey, ensure your machine is equipped with at least a mid-range GPU. This will help you comfortably navigate through the complex simulations.

• Download the project files from the GitHub repository.
• Follow the setup instructions in INSTALL.md to prepare your environment.

Training Your Agents

Training your autonomous driving agents involves specific steps, much like teaching a student to drive. You wouldn’t hand over the keys to a car without ensuring the student knows how to operate it safely.

• Consult the RAILS.md to train your _World-on-Rails_ agent.
• Use LBC.md for instructions on training the _LBC_ agent.

Evaluation of Pretrained Weights

Once you have trained your agents, it’s time to evaluate their performance. An evaluation is like a driving test—how well do they navigate the simulated streets?

• Make sure you launch CARLA with the command line flag -vulkan to evaluate effectively.
• Use the following commands to evaluate your agents:

bash python evaluate.py --agent-config=[PATH TO CONFIG]

• For NoCrash evaluation, use:

bash python evaluate_nocrash.py --town=Town01,Town02 --weather=train,test --agent-config=[PATH TO CONFIG] --resume

Troubleshooting Common Issues

While embarking on this autonomous journey, you may encounter some speed bumps. Here are a few tips to overcome common challenges:

• Problem: CARLA not launching correctly.
• Solution: Ensure you are launching with the -vulkan flag and check your GPU specifications.
• Problem: Training process is slow.
• Solution: Check if your environment is properly set up as per the INSTALL.md guide. Consider closing any other resource-heavy applications.
• Problem: Evaluation results are unclear.
• Solution: Rerun the evaluation commands ensuring that the configuration paths are correctly set. You may also wish to use bash python -m scripts.view_nocrash_results [PATH TO CONFIG.YAML] for a clearer output.
