Sklearn rmse

How to calculate rmse in linear regression python

actual = [0, 1, 2, 0, 3]
predicted = [0.1, 1.3, 2.1, 0.5, 3.1]

mse = sklearn.metrics.mean_squared_error(actual, predicted)

rmse = math.sqrt(mse)

print(rmse)

Sklearn rmsle

import numpy as np
from sklearn.metrics import mean_squared_log_error

def rmse(y_true, y_pred):
	np.sqrt(mean_squared_log_error(y_true, y_pred))
