CARLA Garage: Exploring Hidden Biases in Autonomous Driving Models
The CARLA Garage project is a comprehensive initiative that delves into the nuances of end-to-end autonomous driving models. Rooted in the field of computer vision, this project provides a robust platform for researchers and enthusiasts to explore the intricacies of self-driving models using the CARLA simulator.
Background and Purpose
The crux of the CARLA Garage project is to uncover hidden biases within end-to-end driving models. These models have become pivotal in the realm of autonomous vehicles, aiming to seamlessly integrate perception, decision-making, and control systems. However, biases within these models can lead to unintended consequences. By illuminating these biases, the CARLA Garage project seeks to enhance the reliability and efficiency of autonomous driving technologies.
Key Components
1. Setup and Environment
Setting up the CARLA Garage project involves cloning the repository, configuring the CARLA simulator (version 0.9.10.1), and setting up a suitable Conda environment. Users need to adjust their system's Python path to incorporate various CARLA-related directories, ensuring the code runs smoothly.
2. Pre-Trained Models
The project offers pre-trained models that are readily available for research and experimentation. These models are distributed under the CC BY 4.0 license, allowing for wide academic and developmental use. They are optimized for use with various benchmarks, providing a solid foundation for further research.
3. Evaluation
Evaluating the models involves running them within the CARLA simulator. The evaluation script, leaderboard_evaluator_local.py, has been tailored to match the configuration used in prominent benchmarks, enabling detailed logging and performance analysis. The use of environment variables further refines this process, allowing researchers to adjust settings like inference thresholds and control mechanisms.
4. Dataset
A significant feature of CARLA Garage is its dataset, which is crucial for training the final models. This dataset, also licensed under CC BY 4.0, can be downloaded and used to facilitate training and evaluation processes.
5. Data Generation
Simulating data akin to real-world scenarios is pivotal for training effective models. The project allows for generating datasets through scenarios specified in JSON format. While the generation process is computationally intensive, the ability to distribute tasks across multiple GPUs markedly expedites data creation.
6. Training
Training models in the CARLA Garage project involves the use of state-of-the-art techniques that leverage PyTorch's multi-GPU training capabilities. The methodology supports various configurations, allowing users to tailor experiments according to their specific research needs.
Additional Documentation
For users seeking deeper insights, the project offers detailed documentation covering coordinate systems, model variants, engineering strategies, and other features. These materials provide a thorough understanding of the project's capabilities and configuration.
Community and Contributions
The project acknowledges the contribution of numerous open-source repositories and libraries, highlighting the collaborative nature of technology development. By leveraging these resources, CARLA Garage builds on established technologies to advance the field of autonomous driving.
Conclusion
The CARLA Garage project stands as a vital resource for exploring the critical facets of autonomous driving models. By addressing hidden biases, it not only enhances our understanding of these complex systems but also paves the way for developing more reliable and efficient autonomous vehicles.
