exception evalml.exceptions.exceptions.AutoMLSearchException[source]#: Exception raised when all pipelines in an automl batch return a score of NaN for the primary objective.

exception evalml.exceptions.exceptions.ComponentNotYetFittedError[source]#: An exception to be raised when predict/predict_proba/transform is called on a component without fitting first.

exception evalml.exceptions.exceptions.DataCheckInitError[source]#: Exception raised when a data check can’t initialize with the parameters given.

exception evalml.exceptions.exceptions.MethodPropertyNotFoundError[source]#: Exception to raise when a class is does not have an expected method or property.

exception evalml.exceptions.exceptions.MissingComponentError[source]#: An exception raised when a component is not found in all_components().

exception evalml.exceptions.exceptions.NoPositiveLabelException[source]#: Exception when a particular classification label for the ‘positive’ class cannot be found in the column index or unique values.

exception evalml.exceptions.exceptions.NullsInColumnWarning[source]#: Warning thrown when there are null values in the column of interest.

exception evalml.exceptions.exceptions.ObjectiveCreationError[source]#: Exception when get_objective tries to instantiate an objective and required args are not provided.

exception evalml.exceptions.exceptions.ObjectiveNotFoundError[source]#: Exception to raise when specified objective does not exist.

exception evalml.exceptions.exceptions.ParameterNotUsedWarning(components)[source]#: Warning thrown when a pipeline parameter isn’t used in a defined pipeline’s component graph during initialization.

exception evalml.exceptions.exceptions.PipelineError(message, code, details=None)[source]#

Exception raised for errors that can be raised when applying a pipeline.

Parameters

message (str) – descriptive error message

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

exceptions (dict) – A dictionary mapping an objective name (str) to a tuple of the form (exception, traceback). All of the objectives that errored will be stored here.
