'DecisionTreeClassifier' object has no attribute 'export_graphviz'

Question

I'm using python sklearn RandomForestClassifier and try to export decisiontrees.

The basic code is as following:

from sklearn import tree

with open(dot_file_name, 'w') as my_file:
    tree.export_graphviz(tree1, out_file = my_file,feature_names = feature_names)

After run the python script, following error show up: Attribute error: 'DecisionTreeClassifier' object has no attribute 'export_graphviz'

I'm using python 2.7. Is it because of the version of python? Do I have to use python 3.0?

Solution

That's because you used somewhere tree name as name for DecisionTreeClassifier. Use another name there.
