    Hi @skakkana1,


    Can you share your process and your dataset in order we can reproduce what you observe ?

    Hi @skakkana1,


    Sorry for answering so late. I overlooked your original thread. But we got reports of a similar error and found a bug which is fixed with version 1.5.0 of the Operator Toolbox, released today (2018-09-14)-.


    The problem was that the operator failed when the label attribute contained comparison characters (e.g. =, <, ...). Hopefully this was also the case for your setup and it should be fixed now. If not, feel free to post your problem again, best with the process xml and a sample data set attached.


    Best regards,

    Hi @skakkana1,

    I found that if you want to use SMOTE Upsampling Operator, you should change your attribute name which become label/class to "class".

    I see your attribute which become label is Fraud Flag, so change the name attribute become "class".

    I have same problem and then I change the name attribute, it's work.
