A central task in machine learning and data science is the comparison and selection of models. The evaluation of a single model is very simple, and can be carried out in a reproducible fashion using the standard scikit pipeline. Organizing the evaluation of a large number of models is tricky; while there are no real theory problems present, the logistics and coordination can be tedious. Evaluating a continuously growing zoo of models is thus an even more painful task. Unfortunately, this last case is also quite common.

Reskit is a Python library that helps researchers manage this problem. Specifically, it automates the process of choosing the best pipeline, i.e. choosing the best set of data transformations and classifiers/regressors. The core of reskit is two classes: Pipeliner and Transformer.

First and second sections describe work of this classes. The third section explains how to use this classes for machine learning on graphs.
