Unity ML-Agents Toolkit (Beta)

docs badge license badge

(latest release) (all releases)

The Unity Machine Learning Agents Toolkit (ML-Agents) is an open-source Unity plugin that enables games and simulations to serve as environments for training intelligent agents. Agents can be trained using reinforcement learning, imitation learning, neuroevolution, or other machine learning methods through a simple-to-use Python API. We also provide implementations (based on TensorFlow) of state-of-the-art algorithms to enable game developers and hobbyists to easily train intelligent agents for 2D, 3D and VR/AR games. These trained agents can be used for multiple purposes, including controlling NPC behavior (in a variety of settings such as multi-agent and adversarial), automated testing of game builds and evaluating different game design decisions pre-release. The ML-Agents Toolkit is mutually beneficial for both game developers and AI researchers as it provides a central platform where advances in AI can be evaluated on Unity’s rich environments and then made accessible to the wider research and game developer communities.

Features

  • Unity environment control from Python
  • 15+ sample Unity environments
  • Two deep reinforcement learning algorithms, Proximal Policy Optimization (PPO) and Soft Actor-Critic (SAC)
  • Support for multiple environment configurations and training scenarios
  • Self-play mechanism for training agents in adversarial scenarios
  • Train memory-enhanced agents using deep reinforcement learning
  • Easily definable Curriculum Learning and Generalization scenarios
  • Built-in support for Imitation Learning through Behavioral Cloning or Generative Adversarial Imitation Learning
  • Flexible agent control with On Demand Decision Making
  • Visualizing network outputs within the environment
  • Wrap learning environments as a gym
  • Utilizes the Unity Inference Engine
  • Train using concurrent Unity environment instances
