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

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.
