Multi-Agent Resource Optimization (MARO) platform is an instance of Reinforcement learning as a Service (RaaS) for real-world resource optimization. It can be applied to many important industrial domains, such as container inventory management in logistics, bike repositioning in transportation, virtual machine provisioning in data centers, and asset management in finance. Besides Reinforcement Learning (RL), it also supports other planning/decision mechanisms, such as Operations Research.

Key Components of MARO:

• Simulation toolkit: it provides some predefined scenarios, and the reusable wheels for building new scenarios.
• RL toolkit: it provides a full-stack abstraction for RL, such as agent manager, agent, RL algorithms, learner, actor, and various shapers.
• Distributed toolkit: it provides distributed communication components, interface of user-defined functions for message auto-handling, cluster provision, and job orchestration.

Install MARO from PyPI

• Max OS / Linux

  pip install pymaro
  

• Windows

  # Install torch first, if you don't have one.
  pip install torch===1.6.0 torchvision===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
  
  pip install pymaro
  

Install MARO from Source (Editable Mode)

• Prerequisites

  • C++ Compiler
    • Linux or Mac OS X: gcc
    • Windows: Build Tools for Visual Studio 2017

• Enable Virtual Environment

  • Mac OS / Linux

    # If your environment is not clean, create a virtual environment firstly.
    python -m venv maro_venv
    source ./maro_venv/bin/activate
    

  • Windows

    # If your environment is not clean, create a virtual environment firstly.
    python -m venv maro_venv
    
    # You may need this for SecurityError in PowerShell.
    Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
    
    # Activate the virtual environment.
    .\maro_venv\Scripts\activate
    

• Install MARO

  • Mac OS / Linux

    # Install MARO from source.
    bash scripts/install_maro.sh
    

  • Windows

    # Install MARO from source.
    .\scripts\install_maro.bat
    

Quick Example

from maro.simulator import Env

env = Env(scenario="cim", topology="toy.5p_ssddd_l0.0", start_tick=0, durations=100)

metrics, decision_event, is_done = env.step(None)

while not is_done:
    metrics, decision_event, is_done = env.step(None)

print(f"environment metrics: {env.metrics}")
