================================================================================================================

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 <https://maro.readthedocs.io/en/latest/scenarios/container_inventory_management.html>`_
in logistics, `bike repositioning <https://maro.readthedocs.io/en/latest/scenarios/citi_bike.html>`_
in transportation, `virtual machine <https://maro.readthedocs.io/en/latest/scenarios/vm_scheduling.html>`_ provisioning in data centers, and asset management in finance. Besides
`Reinforcement Learning <https://www.andrew.cmu.edu/course/10-703/textbook/BartoSutton.pdf>`_ (RL),
it also supports other planning/decision mechanisms, such as
`Operations Research <https://en.wikipedia.org/wiki/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 <https://pypi.org/project/pymaro/#files>`_
----------------------------------------------------------------------

*Notes: The CLI commands (including the visualization tool) are not included in pymaro package. To enable these support, you need to install from source.*


*
  Mac OS / Linux

  .. code-block:: sh

    pip install pymaro

*
  Windows

  .. code-block:: powershell

    # 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
------------------------

*Notes: Install from source if you want to use the CLI commands (including the visualization tool).*


*
  Prerequisites


  * C++ Compiler

    * Linux or Mac OS X: ``gcc``
    * Windows: `Build Tools for Visual Studio 2017 <https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15>`_

*
  Enable Virtual Environment


  *
    Mac OS / Linux

    .. code-block:: sh

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

  *
    Windows

    .. code-block:: powershell

       # 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

  .. code-block:: sh

     # Git Clone the whole source code.
     git clone https://github.com/microsoft/maro.git


  *
    Mac OS / Linux

    .. code-block:: sh

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

  *
    Windows

    .. code-block:: powershell

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

*
  *Notes: If your package is not found, remember to set your PYTHONPATH*


  * Mac OS / Linux

  .. code-block:: sh

     export PYTHONPATH=PATH-TO-MARO


  * Windows

  .. code-block:: powershell

     $Env:PYTHONPATH=PATH-TO-MARO

Quick Example
-------------

.. code-block:: python

  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}")

`Environment Visualization <https://maro.readthedocs.io/en/latest/>`_
-------------------------------------------------------------------------

.. code-block:: sh

   # Enable environment dump feature, when initializing the environment instance
   env = Env(scenario="cim",
             topology="toy.5p_ssddd_l0.0",
             start_tick=0,
             durations=100,
             options={"enable-dump-snapshot": "./dump_data"})

   # Inspect environment with the dump data
   maro inspector dashboard --source_path ./dump_data/YOUR_SNAPSHOT_DUMP_FOLDER
