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

• 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

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

  • Mac OS / Linux

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

  • Windows

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

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

  • Mac OS / Linux

  export PYTHONPATH=PATH-TO-MARO

  • Windows

  $Env:PYTHONPATH=PATH-TO-MARO

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}")

Environment Visualization

# 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
