sklearn（scikit-learn）逻辑回归软件包-逻辑回归的返回系数

Question

我想通过交叉验证返回逻辑回归的系数。

from sklearn.model_selection import cross_val_score
from sklearn.preprocessing import StandardScaler
X_train,X_test,y_train,y_test=train_test_split(StandardScaler().fit_transform(X),y,test_size=0.3,random_state=0)
model = LogisticRegression(class_weight= 'balanced')
print(cross_val_score(model, X, y, cv=5, scoring='roc_auc').mean())

当我这样做

Coefficients = model.coef_

它会产生错误** AttributeError：'LogisticRegression'对象没有属性'coef _'**
