出现"DecisionTreeClassif不存在“的错误

Question

我正在尝试学习机器学习。当我尝试创建引用时，它会提示我找不到引用DecisionTreeClassifier

import sklearn as tree

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

Answer 1

DecisionTreeClassifier属于sklearn的tree子模块，所以必须导入它。这应该是可行的：

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