Arcus - Azure Machine Learning

Build Status PyPI version

Azure Machine Learning development in a breeze.



With Arcus we are offering an open source library that streamlines Azure ML development, but lets ML engineers focus on the actual job at hand, without loosing time in tinkering with the AzureML SDK and all overhead that comes with it.

We offer the following concepts:

  • Connectivity to an Azure ML workspace
  • Start experiments on your local development environment (from within Jupyter notebooks or in plain .py scripts)
  • Automatically track every run in an experiment on the Azure ML workspace (even if you execute everything locally). This way you get a perfect overview of all training attempts, the actual parameters, the results and the persisted models
  • Provide tracking & tracing of Grid Searches for Hyper parameter tuning
  • Enable trainings (through standard scripts and dependency files) to be executed locally and in the cloud, using the exact same logic and code.


We are providing added value in every step of the Machine Learning process. With every new release, these features will be extended. Currently we mostly focus on the training and experimentation phase.

  • Interactive experimentations - Evolve your model and experiment with several approaches and parameters, while keeping track of your progress and maintain a reference to every attempt.
  • Scheduling of trainings - Very commonly, you start locally to train and try a model on a smaller set of data, only to evolve to cloud based training on the full data set.
  • Logging metrics of experiments - A key aspect during training, is the logging of the different metrics and results of your experiment or run.
  • Data collection and import - Handy methods to retrieve data and load it into Azure Machine Learning
  • Deployment and hosting (future releases)
  • Feedback (future releases)


The Arcus packages are available through PyPi and can be installed through pip, by executing the following command:

PM > pip3 install arcus-azureml

Upgrading to the latest version can be done by executing the following pip command:

PM > pip3 install --upgrade arcus-azureml 

Every CI build pushes a dev package to the PyPi feed. And when committed, an alpha release is been published on the same feed. These packages can be installed or upgrade, by leveraging the --pre argument for pip.

PM > pip3 install --upgrade --pre arcus-azureml

Local development

It can be quite common that you are using the arcus-ml or arcus-azureml packages on other projects and you need some changes or additional functionality being added to the package. Obviously, it's possible to follow the entire release pipeline (make a PR, get it approved and merged, wait for package to appear on the PyPi feed and upgrade the package). This workflow is too tedious and will not increase your productivity.

The approach to go, is to leverage the following command, which will add a symbolic link to your development directory from the python packages. That way, you always refer to the latest code that is on your development environment. It is advised, though not required to leverage virtual environment (like with conda) for this.

pip install -e /path-to-arcus
