Sinergym

Welcome to Sinergym!

The goal of this project is to create an environment following Gymnasium interface for wrapping simulation engines (EnergyPlus) for building control using deep reinforcement learning or any external control.

For more information about Sinergym, please visit our documentation.

To report questions and issues, please use our issue tracker. We appreciate your feedback and contributions. Check out our CONTRIBUTING.md for more details on how to contribute.

The main functionalities of Sinergym are the following:

• Simulation Engine Compatibility: Uses EnergyPlus Python API for Python-EnergyPlus communication. Future plans include more engines like OpenModelica.

• Benchmark Environments: Designs environments for benchmarking and testing deep RL algorithms or other external strategies, similar to Atari or Mujoco.

• Customizable Environments: Allows easy modification of experimental settings. Users can create their own environments or modify pre-configured ones in Sinergym.

• Customizable Components: Enables creation of new custom components for new environments, making Sinergym scalable, such as function rewards, wrappers, controllers, etc.

• Automatic Building Model Adaptation: Sinergym automates the process of adapting the building model to user changes in the environment definition.

• Automatic Actuators Control: Controls actuators through the Gymnasium interface based on user specification, only actuators names are required and Sinergym will do the rest.

• Extensive Environment Information: Provides comprehensive information about Sinergym background components from the environment interface.

• Stable Baseline 3 Integration: Customizes functionalities for easy testing of environments with SB3 algorithms, such as callbacks and customizable training real-time logging. However, Sinergym is agnostic to any DRL algorithm.

• Google Cloud Integration: Offers guidance on using Sinergym with Google Cloud infrastructure.

• Weights & Biases Compatibility: Automates and facilitates training, reproducibility, and comparison of agents in simulation-based building control problems. WandB assists in managing and monitoring model lifecycle.

• Notebook Examples: Provides code in notebook format for user familiarity with the tool.

• Extensive Documentation, Unit Tests, and GitHub Actions Workflows: Ensures Sinergym is an efficient ecosystem for understanding and development.

• And much more!

This is a project in active development. Stay tuned for upcoming releases.

Installation

Please visit INSTALL.md for detailed installation instructions.

Usage example

If you used our Dockerfile during installation, you should have the try_env.py file in your workspace as soon as you enter in. In case you have installed everything on your local machine directly, place it inside our cloned repository. In any case, we start from the point that you have at your disposal a terminal with the appropriate python version and Sinergym running correctly.

Sinergym uses the standard Gymnasium API. So a basic loop should look like:

import gymnasium as gym
import sinergym
# Create the environment
env = gym.make('Eplus-datacenter-mixed-continuous-stochastic-v1')
# Initialize the episode
obs, info = env.reset()
truncated = terminated = False
R = 0.0
while not (terminated or truncated):
    a = env.action_space.sample() # random action selection
    obs, reward, terminated, truncated, info = env.step(a) # get new observation and reward
    R += reward
print('Total reward for the episode: %.4f' % R)
env.close()

A folder will be created in the working directory after creating the environment. It will contain the Sinergym outputs produced during the simulation.

For more examples and details, please visit our usage examples documentation section.

Installation

Sinergym relies on several dependencies, the specifics of which vary by version. The table below provides a summary of the versions supported by Sinergym across its releases:

Sinergym version	Ubuntu version	Python version	EnergyPlus version	Building model file
0.0	18.04 LTS	3.6	8.3.0	IDF
1.1.0	18.04 LTS	3.6	9.5.0	IDF
1.7.0	18.04 LTS	3.9	9.5.0	IDF
1.9.5	22.04 LTS	3.10.6	9.5.0	IDF
2.4.0	22.04 LTS	3.10.6	9.5.0	epJSON
2.5.0	22.04 LTS	3.10.6	23.1.0	epJSON
3.3.6	24.04 LTS	3.12.3	23.1.0	epJSON
3.5.8	24.04 LTS	3.12.3	24.1.0	epJSON

We recommend always using the latest version of Sinergym that is supported by the container. This approach helps you avoid the complexities of the installation process. However, if you prefer to manually install Sinergym on your computer, we provide the necessary documentation in the subsequent sections.

Docker container

We provide a Dockerfile to install all dependencies and prepare the image for running Sinergym. This is the recommended option, since it ensures that all dependencies and versions are correctly installed and configured.

In essence, this Dockerfile installs the compatible operating system, EnergyPlus, Python, and Sinergym, along with the necessary dependencies for its proper functioning. If you have cloned the repository, it can be used as follows:

$ docker build -t <tag_name> .

However, Sinergym has a set of optional dependencies that enhance the tool's usage. These dependencies can be installed in the following way when building the image:

$ docker build -t <tag_name> --build-arg SINERGYM_EXTRAS="drl notebooks gcloud" .

These optional dependencies allow you to use stable-baselines3, wandb, notebooks or gcloud directly. For more information, please refer to the pyproject.toml file at the root of the repository ([tool.poetry.extras] section). If you desire to install all optional packages, you can use extras directly in the SINERGYM_EXTRAS argument.

:memo: Note: Our container can also be directly installed from the Docker Hub repository. It contains all the project's releases with secondary dependencies or lite versions.

Once the container image is ready, you can execute any command as follows:

$ docker run -it --rm <tag_name> <command>

By default, the command executed is python scripts/try_env.py, which is a minimal working example.

If you want to run a DRL experiment, for example, you can do it like this:

$ docker build -t example/sinergym:latest --build-arg SINERGYM_EXTRAS="drl" .
$ docker run -e WANDB_API_KEY=$WANDB_API_KEY -it --rm example/sinergym:latest python scripts/train/train_agent.py -conf scripts/train/train_agent_PPO.json

If the script you want to use requires a WandB account, remember to include the environment variable in the container with the token.

It’s also possible to keep a session open in the image to copy and run your own scripts. For more information, please refer to the Docker documentation. This can be useful when you want to run your own scripts in the container.

$ docker run -it <tag_name> /bin/bash

:memo: Note: For Visual Studio Code users, simply open the root directory and click on the Reopen in container pop-up button. This action will automatically install all dependencies and enable you to run Sinergym in an isolated environment. For more details on this feature, refer to the VSCode Containers extension documentation.

Manual installation

If you prefer not to use containers and have everything installed natively on your system, we’ll explain how to do it.

First, make sure that you meet the compatibility matrix; otherwise, no support or guarantees of functionality will be provided by the development team.

Configure Python Environment

Start by installing the desired version of Python and pip. It is recommended to set up a working environment for Python (multiple options are available). Finally, install the necessary dependencies for Sinergym in that environment:

$ pip install sinergym

You can also install the optional packages from here, just like in the Docker container:

$ pip install sinergym[extras]

If you want to install the cloned repository directly, you can do so by running the following command in its root.

$ poetry install --no-interaction --only main --extras <optional_extras>
# or
$ pip install .[<optional_extras>]

With this, you have the correct Python version and the necessary modules to run Sinergym. Let's proceed with the installation of other required programs outside of Python to run the simulations.

Install EnergyPlus 24.1.0

You need to install EnergyPlus. We have tested and confirmed compatibility with version 24.1.0. The code might work with other versions, but we have not tested them.

Follow the instructions here to install it for Linux (we only support Ubuntu). You can choose any location for the installation. After installation, a folder named Energyplus-24-1-0 should appear in the chosen location.

Include Energyplus Python API in Python Path

Sinergym uses the Energyplus Python API as its backend. The modules of this API are located in the Energyplus folder that you installed in the previous step. You must add this installation path to the PYTHONPATH environment variable so that the interpreter can access these modules.

Develop in Sinergym

Whether you have chosen to use Docker or a manual installation, we offer facilities for developing and extending Sinergym.

If you've used a container, Visual Studio Code will set up a development environment with all the necessary packages automatically, including documentation, tests, DRL, etc integrated in the IDE. If you've opted to use a container without Visual Studio Code, you can use the Dockerfile available in the .devcontainer folder instead of the one in the root of the repository. If you are creating your own Dockerfile, make sure to perform the following installation so that all development modules are available:

RUN poetry install --no-interaction

The default installation includes all development packages. To avoid this, you should specify --only main or --without <develop_groups>. The development groups can also be found in pyproject.toml.

If you have manually installed the project, you can install the development packages from Poetry in the same way. Once the repository is cloned, run the same command we explained earlier, adding the following:

$ poetry install --no-interaction

As you can see, the command is the same as the one shown in the manual installation section, but without specifying groups or extras, so that all development packages are installed. In this case, it is not possible to use pip because it does not include information about development dependencies (except those listed in extras).

:memo: For more information on how Poetry dependencies work, visit the official documentation.

Verify Installation

This project is automatically monitored using tests specifically developed for it. To verify that Sinergym has been installed correctly, execute pytest tests/ -vv in the repository root. Remember to have installed test extra packaging to use it.

Furthermore, each time the Sinergym repository is updated, the tests are automatically executed in a remote container built using the Dockerfile. This task is performed by Github Action (refer to the Github Actions section for more details).

Cloud Computing

You also have the option to run your experiments in the Cloud. We utilize Google Cloud for this purpose. Our team is working on setting up an account to run our Sinergym container with remote storage and Weights&Biases tracking. For more information on installation and preparing the Google Cloud SDK to run your experiments, please visit our Preparing Google Cloud section.
