from sklearn.ensemble import MetaEstimator

# Base estimators
est1 = Model1()
est2 = Model2()
estN = ModelN()

# Meta estimator
est_combined = MetaEstimator(
   estimators=[est1, est2, ..., estN],
   # Additional parameters
)

# Train and test
est_combined.fit(X_train, y_train)

pred = est_combined.predict(X_test)
