Welcome to the world of Reinforcement Learning (RL), where agents are trained to make decisions through interactions within their environments. In this guide, we will explore how to set up and utilize the RLs framework based on PyTorch. This framework provides a robust platform for experimenting with both classic and state-of-the-art reinforcement learning algorithms.

Getting Started

Before we journey further, let’s get our environment ready through a simple installation process. Here are the steps to follow:

• First, clone the repository:

git clone https://github.com/StepNeverStopRLs.git

• Navigate into the project directory:

cd RLs

• Create and activate a new Conda environment:

conda create -n rls python=3.8

conda activate rls

• Install the required packages:
• For Windows:

pip install -e .[windows]

• For Linux or Mac OS:

pip install -e .

Core Features and Characteristics

RLs is designed to be versatile and user-friendly, offering:

• Support for Windows, Linux, and OSX.
• Single and multi-agent training.
• Flexible observation sensors for input.
• A straightforward approach to implement new algorithms and adapt to different environments.

Understanding Project Structure: An Analogy

Think of this project as a well-organized kitchen. The ingredients you need (algorithms and environments) are placed on the shelves (directories). Cooking (training agents) happens at the stove (main files) where different pots (algorithms) are simmering based on the recipes (configuration files) you prepared earlier:

• Ingredients: The algorithms, which you can find in rls/algorithms/single and rls/algorithms/multi.
• Recipes: Configuration files located in rls/configs/algorithms.
• Cooking Tools: The environment wrappers situated in rls/envs/new_platform.

Implementing Your Own Algorithm

To implement a new reinforcement learning algorithm, follow these steps:

1. Create a Python file in the appropriate algorithms directory and inherit from the base class specified.
2. Create a configuration file in the configs directory to specify the super config type.
3. Register the new algorithm in rls/algorithms/__init__.py.

This simplicity allows you to experiment and prototype new ideas in no time!

Troubleshooting Tips

If you encounter any issues during installation or usage, here’s what you can do:

• Ensure that you have the right version of Python (3.8) installed.
• If you face dependency issues, try re-installing the packages.
• For issues related to environment setup, double-check the paths in your YAML configuration files.
