Python 3:NameError:name'；sklearn'；没有定义

我正在尝试运行弹性网络回归，但出现以下错误：NameError:name'sklearn'未定义。。。非常感谢您的帮助

因为您已经导入了

linear\u模型

改变

ElasticNet=sklearn.linear\u model.ElasticNet（）

到

---

ElasticNet=linear\u model.ElasticNet（）

使用

linear\u model.ElasticNet（）

。放下

sklearn

    # ElasticNet Regression 

    from sklearn import linear_model
    import statsmodels.api as sm

    ElasticNet = sklearn.linear_model.ElasticNet() # create a lasso instance
    ElasticNet.fit(X_train, y_train) # fit data

    # print(lasso.coef_)
    # print (lasso.intercept_) # print out the coefficients

    print ("R^2 for training set:"),
    print (ElasticNet.score(X_train, y_train))

    print ('-'*50)

    print ("R^2 for test set:"),
    print (ElasticNet.score(X_test, y_test))
