"Need help with decision tree"
Hi, I can't seem to get the decision tree to work even though there are no errors when I hit run button. I have a simple csv file with three columns, they are all text values.
In the design workspace I have a Read CSV file connected to a Set Role which is connected to the tree, but I can't see the tree view or get a result.
Thanks.

Hi chobo,
it seems you simply forget to connect the model output out your DecisionTree operator to the results. Try this process:

Your description is rather unspecific. Please copy the process from the xml tab into this thread, best into the code-area ("#"-symbol). Then we have something to think about.
