pipeline的用法

  models = [Pipeline([
        ('poly', PolynomialFeatures()),
        ('linear', LinearRegression(fit_intercept=False))]),
        Pipeline([
            ('poly', PolynomialFeatures()),
            ('linear', RidgeCV(alphas=*****, fit_intercept=False))]),
        Pipeline([
            ('poly', PolynomialFeatures()),
            ('linear', LassoCV(alphas=****, fit_intercept=False))]),
        Pipeline([
            ('poly', PolynomialFeatures()),
            ('linear', ElasticNetCV(alphas=***, l1_ratio=***,
                                    fit_intercept=False))])
    ]
