"X-Validation e Set Role"

By using X-Validation, the following message appears:

The example in September does not have a label.
Many operators in particular classification and regression algorithms require the target attribute to be declared as so the label.To, use "The set role" operator.

How should I proceed?

How should I configure the Set Role?

    You need to add a label attribute. A label is something where the truth is in (sometimes target variable).

    So you need to set the role of the attribute you want to predict to "label" using the set role operator
