Unreleased

0.4.2 - 2020-11-15

Fixed

  • Fix a bug where Model.fit would fail for unhashable steps (PR #43).

Changed

  • Deprecate default value of class_name argument in make_step function (PR #45).

0.4.1 - 2020-05-17

Fixed

  • Fix bug in repr of Model class (PR #35).

0.4.0 - 2020-05-16

Added

  • Add capability to specify a name to the class made by make_step (PR #34).

Fixed

  • Improved and fixed a bug in repr of steps that causes a RuntimeError for scikit-learn 0.23.0. (PR #33).

  • Fix bug where *args was not included in the constructor of the class made by make_step (and fix related examples in the docs) (PR #34).

0.3.1 - 2020-04-26

Fixed

  • Fix bug where get_params would break when the base class did not implement an __init__ method (PR #32).

0.3.0 - 2020-02-23

Added

  • Add support for shared steps (PR #19). Now steps can be called several times on different inputs.

    • This is a backwards-incompatible change. The outputs of the steps now follow the following format: step_name:port/output_number. (Previously it was step_name/output_number)

  • Add option to include targets in plot_model (PR #20).

  • Add new fit_compute_func argument to Step.__call__ that allows to specify custom behavior at fit time (PR #22).

  • Add documentation built with Sphinx and hosted on baikal.readthedocs.io (PR #29).

Changed

  • Move compute_func (previously function) and trainable args to Step.__call__ (PR #18).

    • Also, the default value is changed from None to "auto".

    • This is a backwards-incompatible change.

  • Raise RuntimeError chained with the original exception in Model.fit and Model.predict.

Fixed

  • Add clarification in that steps must be named in build_fn when using SKLearnWrapper

  • Fix bug where the compute function was not being transferred when replacing a step in Model.set_params.

  • Fix an API inconsistency regarding the handling of the arguments of fit/compute for steps with multiple inputs and targets (PR #21).

  • Fix several bugs in plot_model (it was largely broken) (PR #20, PR #24).

0.2.0 - 2019-11-16

Added

  • This CHANGELOG file.

  • Introduced new targets API (PR #1).

    • Steps now take an optional targets argument at call time to specify inputs for target data at fit time.

    • Correspondingly, Model also takes an additional argument for these targets.

    • The extra_targets argument in Model.fit was removed.

  • Step enhancements

    • make_step factory function to ease definition of steps.

    • Added support for function arguments to Lambda step (PR #8).

    • Added new Split step (PR #9).

Fixed

  • Some refactoring and minor fixes.

  • Bug fixes (PR #6, PR #7)

0.1.0 - 2019-06-01
