Project Title

Gymnasium — A Standard API for Single-Agent Reinforcement Learning Environments

Overview

Gymnasium is an open-source Python library that provides a standard API for developing and comparing reinforcement learning algorithms. It offers a wide range of environments compliant with the API, making it easier to test and compare different algorithms. This project is a fork of OpenAI's Gym library, where future maintenance will occur.

Key Features

• Standard API for communication between learning algorithms and environments
• A variety of environments, including Classic Control, Box2D, Toy Text, MuJoCo, Atari, and third-party environments
• Comprehensive documentation and a public Discord server for community support
• Easy installation and dependency management

Use Cases

• Researchers and developers using reinforcement learning to test and compare different algorithms
• Educators using Gymnasium environments for teaching purposes
• Companies developing AI solutions that require reinforcement learning capabilities

Advantages

• Supports a wide range of environments, making it versatile for various use cases
• Active community and regular updates ensure the library stays up-to-date with the latest advancements
• Easy to install and use, with clear documentation and examples

Limitations / Considerations

• Windows support is not officially provided, though PRs related to Windows are accepted
• Some environments have dependencies that can be challenging to install on certain systems
