MLeap For Spark

MLeap deploys Spark ML (and some MLlib) transformers and pipelines to production without a Spark Context.

MLeap For Scikit-Learn

MLeap extends scikit-learn's functionality to be able to serialize and deploy scikit transformers, pipelines and feature unions without any dependencies on scikit (numpy, scipy, c++ libraries). It also serializes transformers and pipelines as Spark, so you can load and deploy your scikit pipelines on Spark infrastructure with a few lines of code.

Tutorials
