特征选择错误：The classifier does not expose coef_ or feature_importances_ attributes
在利用RFE进行特征筛选的时候出现问题，源代码如下： from sklearn.svm import SVRmodel_SVR = SVR(C=1.0, cache_size=200, coef0=0.0, degree=3, epsilon=0.1, gamma='auto',kernel='rbf', max_iter=-1, shrinking=True, tol=0.001, verb
python实现RF.feature_importances的条形图
