Module pipeline (1.34.0)

For composing estimators together. This module is styled after scikit-learn's pipeline module: https://scikit-learn.org/stable/modules/pipeline.html .

Pipeline of transforms with a final estimator.

Sequentially apply a list of transforms and a final estimator. Intermediate steps of the pipeline must be transforms . That is, they must implement fit and transform methods. The final estimator only needs to implement fit .

The purpose of the pipeline is to assemble several steps that can be cross-validated together while setting different parameters. This simplifies code and allows for deploying an estimator and preprocessing together, e.g. with Pipeline.to_gbq(...).
