EmeraldML
A machine learning library for streamlining the process of
(1) cleaning and splitting data,
(2) training, optimizing, and testing various models based on the task, and
(3) scoring and ranking them
during the exploratory phase for an elementary analysis of which models perform better for a specific dataset.

from emerald.boa import RegressionBoa
rboa = RegressionBoa(random_state=3)
rboa.hunt(data=audi, target='price')
