This package contains the PMMLLinearRegression (lm in R) as well as PMMLRidge, PMMLLasso and PMMLElasticNet (glm and glmnet in R).
A minimal working example is shown below:
import pandas as pd
from sklearn_pmml_model.linear_model import PMMLLinearRegression
# Prepare data
df = pd.read_csv('models/categorical-test.csv')
Xte = df.iloc[:, 1:]
clf = PMMLLinearRegression(pmml="models/linear-model-lm.pmml")
clf.predict(Xte)
