Hello, I'm trying the Python Decision tree example code from this website: https://medium.com/@rnbrown/creating-and-visualizing-decision-trees-with-python-f8e8fa394176
All lines execute without any problems except the very last one to produce the image. When I run it I get the following error message: *InvocationException: GraphViz's executables not found* I'm pasting the full code below. Thanks *import sklearn.datasets as datasets* *import pandas as pd* *iris=datasets.load_iris()* *df=pd.DataFrame(iris.data, columns=iris.feature_names)* *y=iris.target* *from sklearn.tree import DecisionTreeClassifier* *dtree=DecisionTreeClassifier()* *dtree.fit(df,y)* *from sklearn.externals.six import StringIO * *from IPython.display import Image * *from sklearn.tree import export_graphviz* *import pydotplus* *dot_data = StringIO()* *export_graphviz(dtree, out_file=dot_data, * * filled=True, rounded=True,* * special_characters=True)* *graph = pydotplus.graph_from_dot_data(dot_data.getvalue()) * *Image(graph.create_png()) * -- You received this message because you are subscribed to the Google Groups "spyder" group.
