export\u graphviz extratreesclassifier python可视化

我认为没有办法从 sklearn。表演团体树外分类器 .

但是你可以用一棵树从 sklearn。树外部分类器 .

from sklearn import tree
...

#Fit an Extra Tree model to the data
model = tree.ExtraTreeClassifier()
model.fit(X_train, y_train)

#Use http://webgraphviz.com to visualize the graph of this file
with open("tree_classifier.txt", "w") as f:
    f = tree.export_graphviz(model, out_file=f)

下面是一个决策树示例,该示例也适用于额外的树: http://dataaspirant.com/2017/04/21/visualize-decision-tree-python-graphviz/
