Helper

This module provides helper functions and classes for the user. They make working with skorch easier but are not used by skorch itself.

SliceDict

A SliceDict is a wrapper for Python dictionaries that makes them behave a little bit like numpy.ndarrays. That way, you can slice your dictionary across values, len() will show the length of the arrays and not the number of keys, and you get a shape attribute. This is useful because if your data is in a dict, you would normally not be able to use sklearn GridSearchCV and similar things; with SliceDict, this works.
