Python 3：NameError：名称'sklearn'未定义

Question

我想运行弹性网络回归但出现以下错误：NameError：名称'sklearn'未定义...任何帮助非常感谢！

# 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)) 

Answer 1

正如你所进口linear_model

变化

ElasticNet = sklearn.linear_model.ElasticNet()

到

ElasticNet = linear_model.ElasticNet()
