exception evalml.exceptions.exceptions.PipelineNotFoundError[source]#

An exception raised when a particular pipeline is not found in automl search results.

exception evalml.exceptions.exceptions.PipelineNotYetFittedError[source]#

An exception to be raised when predict/predict_proba/transform is called on a pipeline without fitting first.

exception evalml.exceptions.exceptions.PipelineScoreError(exceptions, scored_successfully)[source]#

An exception raised when a pipeline errors while scoring any objective in a list of objectives.

Parameters

  • scored_successfully (dict) – A dictionary mapping an objective name (str) to a score value. All of the objectives that did not error will be stored here.
