We have open sourced the toolkit behind www.ramp.studio and all the starting kits. You can use rampwf to build your own predictive workflows, organize workflow building and optimization within an internal data science team, and submit the kit to us if you want to run a code submission data challenge. https://www.ramp.studio https://github.com/paris-saclay-cds/ramp-workflow https://github.com/ramp-kits https://ramp-studio.slack.com
