What it is

Gym is a toolkit for developing and comparing reinforcement learning algorithms. It provides a standard API to interact with environments, making it easier to test different RL methods across various tasks.

Gym provides a standardized and extensible framework for developing, testing, and comparing reinforcement learning algorithms across various environments.

When it fits — and when it doesn’t

A good fit for

  • Researchers looking to benchmark their reinforcement learning algorithms against standard environments

  • Developers who need a consistent API for interacting with various reinforcement learning environments

Look elsewhere if

  • Projects requiring real-time interaction with physical systems (due to its local nature)

  • Teams needing cloud-based solutions for large-scale RL training

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited support for non-standard environments

    Custom environment integration requires significant effort and documentation is sparse on this topic

  2. 02

    Performance bottlenecks in large-scale deployments

    Gym's architecture can lead to performance issues when scaling up the number of parallel environments

What it does well

  • Standardized API for reinforcement learning environments

  • Wide range of pre-built environments for testing algorithms

  • Easy to extend with custom environments
