我想同时应用交叉验证和过采样。我从这段代码中得到以下错误：
from sklearn.pipeline import Pipeline, make_pipeline
imba_pipeline = make_pipeline(SMOTE(random_state=42),
LogisticRegression(C=3.4))
cross_val_score(imba_pipeline, X_train_tf, y_train, scoring='f1-weighted', cv=kf)
所有中间步骤应该是转换器并实现拟合和转换，或者是字符串 'passthrough' 'SMOTE(k_neighbors=5, kind='deprecated', m_neighbors='deprecated', n_jobs=1, out_step='deprecated', random_state=42 , ratio=None, sampling_strategy='auto', svm_estimator='deprecated')' (type ) 不
附注。我用得到同样的错误imblearn.over_sampling.RandomOverSampler而非SMOTE。
