“DecisionTreeClassif不存在”获取错误

Question

我在努力学习机器学习。当我试图创建一个DecisionTreeClassifier时，它说找不到引用DecisionTreeClassifier

import sklearn as tree

// Get the error hear
clf = tree.DecisionTreeClassifier()

Answer 1

DecisionTreeClassifier属于sklearn的tree子模块，因此必须导入它。这应该起作用：

import sklearn.tree as tree
clf = tree.DecisionTreeClassifier()
