Welcome to the world of BARK, a semantic simulation framework tailored for autonomous driving. With its behavior model-centric approach, BARK enables swift development, training, and benchmarking of diverse decision-making algorithms.

Why BARK?

BARK is designed for computationally demanding tasks, primarily reinforcement learning, making it an excellent resource for both Python developers and C++ researchers.

How to Use BARK

BARK can be utilized in two primary ways depending on your expertise and requirements:

(A) Installation via Pip Package

This approach is ideal for Python enthusiasts implementing behavior models or machine learning scientists utilizing BARK-ML. Follow these steps:

• Ensure your environment is set up for Ubuntu or MacOS and Python version 3.7.
• Install BARK using the following command:

pip install bark-simulator

• After installation, explore the available examples to discover how to utilize BARK in different scenarios.

(B) Building from Source

This section caters to C++ developers creating their own behavior models or researchers conducting benchmarks:

• Clone the repository using this command:

git clone https://github.com/bark-simulator/bark.git

• For installation instructions, refer to How to Install BARK.
• Run IPython Notebook tutorials using:

bazel run docs/tutorials:run

Understanding the Code: An Analogy

To better comprehend the installation process of BARK, let’s compare it to setting up a new kitchen:

• **Choosing Your Tools (Installation)**: Just as you select knives, pots, and pans to suit your cooking style, you determine whether to use pip (a toolkit) or build from the source (constructing your kitchen from scratch).
• **Reading Recipes (Documentation)**: Like following a recipe, you’ll refer to the BARK documentation to learn how different components work together.
• **Juggling with Ingredients (Examples)**: You’d experiment with various ingredients, akin to testing out BARK examples in different driving scenarios.

Troubleshooting

If you encounter any issues during installation or usage, consider the following troubleshooting tips:

• Work in a fresh Python virtual environment to avoid conflicts with existing packages.
• Ensure that all dependencies are correctly installed by reviewing the installation documentation.
• Check GitHub issues for any similar encountered problems and their solutions.
