of steps in processing the data, for example feature selection, normalization
and classification. :class:`Pipeline` serves two purposes here:
- Convenience: You only have to call ``fit`` and ``predict`` once on your data to

For estimators to be usable within a pipeline, all except the last one need to have
a ``transform`` function. Otherwise, the dataset can not be passed through this
