Welcome to the exciting world of Tactics2D, a powerful open-source Python library designed to create diverse traffic scenarios tailored for reinforcement learning models in autonomous driving. This article will walk you through how to get started with Tactics2D, install it, and troubleshoot common issues you might encounter along the way.

What is Tactics2D?

Tactics2D is an innovative library that provides various traffic scenarios, enabling the development and evaluation of decision-making models based on reinforcement learning. With features like compatibility with real-world trajectory datasets, customizable road elements, and user-friendly visualization tools, Tactics2D is tailored for researchers and developers alike.

Key Features of Tactics2D

• Compatibility: Imports real-world trajectory datasets and parses commonly used map formats.
• Customizability: Create new traffic participant classes and road elements.
• Diversity: Offers an extensive range of built-in traffic scenarios, from highways to parking lots.
• Visualization: Real-time rendering of traffic conditions for better analysis.
• Reliability: Over 85% code coverage through unit tests.

How to Install Tactics2D

Ready to dive in? Let’s install Tactics2D! We highly recommend using conda to manage your Python environment. If you don’t have conda installed, you can download it from the link provided.

1. System Requirements

Make sure your system meets the requirements listed below:

• Python versions: 3.8, 3.9, 3.10, 3.11
• Compatible operating systems: Ubuntu, Windows, MacOS

2. Create a Conda Environment

First, create a new conda environment using the command below:

conda create -n tactics2d python=3.9

3. Install Tactics2D

You can install Tactics2D directly from PyPI with the following command:

pip install tactics2d

Alternatively, if you want to contribute to the development or run sample codes, you can install it from GitHub:

git clone --recurse-submodules git@github.com:WoodOxen/tactics2d.git
cd tactics2d
pip install -v .

Ensure you have GCC installed on your operating system before proceeding with this method.

4. Dataset Preparation

Tactics2D does not include original datasets due to licenses, so you will need to download them from their official sites. Currently supported datasets include Argoverse, Dragon Lake Parking (DLP), HighD, InD, RounD, ExiD, INTERACTION, NuPlan, and Waymo Open Motion Dataset (WOMD).

Unique Scenarios in Tactics2D

Just like an orchestra requires a diverse set of instruments to create harmony, Tactics2D offers an array of traffic scenarios that allow your models to adapt to various driving environments:

• Highway Cases: Simulate realistic conditions with datasets like HighD and ExiD.
• Intersection Cases: Tackle complex intersections using datasets such as InD, Argoverse, and more.
• Roundabouts: Provide a fun challenge for your models.
• Parking Cases: Prepare your models to handle various parking challenges.
• Racing Cases: For scenarios that require speed and agility.

Troubleshooting

Even the most seasoned developers may encounter issues during installation or setup. Here are some common troubleshooting tips:

• Environment Issues: Ensure you’re using the right version of Python and that your environment is activated.
• Dataset Not Found: Double-check that you have downloaded the datasets to the correct directory specified in the parser.
• Dependencies Missing: Make sure to install all dependencies outlined in the documentation.
• Performance Issues: If your scenarios run slowly, ensure you have the latest graphics drivers and sufficient system resources.
• If you need more assistance, feel free to visit the Discord Community or check out the documentation for more detailed information.
