Scikit-learn is an open source Python library that efficiently implements multiple machine learning algorithms for classification, regression, and clustering.

Compute the root mean square error (RMSE) with Scikit-learn

import math
import sklearn.metrics

setA = [5, 10, 15, 20]
setB = [4, 8, 16, 20]

rmse = math.sqrt(
	sklearn.metrics.mean_squared_error(setA, setB)
