How are you? I am trying to create a decision tree with the RapidMiner, but I am getting some errors. I am using select attributes, set roles, and split validation operators. Decision tree, apply model, and performance (bionomial classification) operators are nested within the Split-validation. I am trying to disretize (by size) the label, but I am getting errors. The probem view says like:

Performace bionomial classification cannot handle numerical laber, and cannot evaluate of type real. Thanks so much!

    Can you share the code of your process so that we can have a look? 

    It sounds like something might be connected in the wrong order.  Are any of your connections coloured in red? 


    Have a look also at the Problems view to see if there are any quick fix solutions. 

    View -> Show Panel -> Problems. 


    Hope that helps.
