Go through the code block given below:

python
from sklearn.preprocessing import PolynomialFeatures
from sklearn.pipeline import Pipeline
from sklearn.preprocessing import StandardScaler
from sklearn.linear_model import RidgeCV
from sklearn.datasets import load_diabetes
diabetes = load_diabetes(as_frame=True)
train_X= diabetes.data
train_y= diabetes.target


lf= np.logspace(-5, 0, num=6)


reg= Pipeline([("poly", PolynomialFeatures(degree=2)),
                            ("feature_scaling", StandardScaler())
                            ])


ridge= RidgeCV(alphas=lf,scoring= None,fit_intercept = False)
