Applied Reinforcement Learning with Python

MazeRL is an application oriented Deep Reinforcement Learning (RL) framework, addressing real-world decision problems. Our vision is to cover the complete development life cycle of RL applications ranging from simulation engineering up to agent development, training and deployment.

This is a preliminary, non-stable release of Maze. It is not yet complete and not all of our interfaces have settled yet. Hence, there might be some breaking changes on our way towards the first stable release.

Spotlight Features

Below we list a few selected Maze features.

  • Design and visualize your policy and value networks with the Perception Module. It is based on PyTorch and provides a large variety of neural network building blocks and model styles. Quickly compose powerful representation learners from building blocks such as: dense, convolution, graph convolution and attention, recurrent architectures, action- and observation masking, self-attention etc.
  • Create the conditions for efficient RL training without writing boiler plate code, e.g. by supporting best practices like pre-processing and normalizing your observations.
  • Maze supports advanced environment structures reflecting the requirements of real-world industrial decision problems such as multi-step and multi-agent scenarios. You can of course work with existing Gym-compatible environments.
  • Use the provided Maze trainers (A2C, PPO, Impala, SAC, Evolution Strategies), which are supporting dictionary action and observation spaces as well as multi-step (auto-regressive policies) training. Or stick to your favorite tools and trainers by combining Maze with other RL frameworks.
  • Out of the box support for advanced training workflows such as imitation learning from teacher policies and policy fine-tuning.
  • Keep even complex application and experiment configuration manageable with the Hydra Config System.

Get Started

  • Make sure PyTorch is installed and then get the latest released version of Maze as follows:

    pip install -U maze-rl
    

    Read more about other options like the installation of the latest development version.

    ⚡ We encourage you to start with Python 3.7, as many popular environments like Atari or Box2D can not easily be installed in newer Python environments. Maze itself supports newer Python versions, but for Python 3.9 you might have to install additional binary dependencies manually

  • Alternatively you can work with Maze in a Docker container with pre-installed Jupyter lab: Run docker run -p 8888:8888 enliteai/maze:playground and open localhost:8888 in your browser. This loads Jupyter

  • To see Maze in action, check out a first example.

  • Try your own Gym env or visit our Maze step-by-step tutorial.
