Automated Pipeline search.

Methods

`__init__`	Automated pipeline search
`add_to_rankings`	Fits and evaluates a given pipeline then adds the results to the automl rankings with the requirement that automl search has been run.
`describe_pipeline`	Describe a pipeline
`get_pipeline`	Given the ID of a pipeline training result, returns an untrained instance of the specified pipeline initialized with the parameters used to train that pipeline during automl search.
`load`	Loads AutoML object at file path
`save`	Saves AutoML object at file path
`search`	Find best classifier

Attributes

`best_pipeline`	Returns an untrained instance of the best pipeline and parameters found during automl search.
`data_check_results`
`full_rankings`	Returns a pandas.DataFrame with scoring results from all pipelines searched
`has_searched`	Returns True if search has been ran and False if not
`rankings`	Returns a pandas.DataFrame with scoring results from the highest-scoring set of parameters used with each pipeline.
`results`	Class that allows access to a copy of the results from automl_search.
