Oríon

Current PyPi Version Supported Python Versions BSD 3-clause license DOI Documentation Status Codecov Report Github actions tests

Oríon is an asynchronous framework for black-box function optimization.

Its purpose is to serve as a meta-optimizer for machine learning models and training, as well as a flexible experimentation platform for large scale asynchronous optimization procedures.

Core design value is the minimum disruption of a researcher's workflow. It allows fast and efficient tuning, providing minimum simple non-intrusive (not even necessary!) helper client interface for a user's script.

So if ./run.py --mini-batch=50 looks like what you execute normally, now what you have to do looks like this:

orion -n experiment_name ./run.py --mini-batch~'randint(32, 256)'

Check out our getting started guide or this presentation for an overview, or our scikit-learn example for a more hands-on experience. Finally we encourage you to browse our documentation.

Why Oríon?

Effortless to adopt, deeply customizable

Installation

Install Oríon by running $ pip install orion. For more information consult the installation guide.
