    Hi!

    You need to be careful with Process Documents ... and check if your setup keeps the label role on the Sentiment attribute before sending the data into Cross Validation.

    你可以年代et a "breakpoint after" on the upper Process Documents, or a "breakpoint before" on the cross validation. You'll then see if the attribute is still having the label role. The error message from the cross validation indicates that this is not the case.

    It might be necessary to move Set Role to act after Process Documents.

    Regards,
