Label column not available or not yet selected for SUPERVISED training.

I get the following - WARN DL4J Feedforward Learner (Classification) 0:15 Label column not available or not yet selected for SUPERVISED training. Domain of Label column may not be available.

In the Error Log as well as when I attempt to configure the FL4J Feedforward Learner (Classification). Here is a image of my model:

CancerModel
CancerModel2624Ă—1494 738 KB

as well as the input table.

InputTable
InputTable2558Ă—1556 788 KB

The Class column is the type of cancer the model is trying to predict (using gene expression data).

This is with Knime 3.7. I am not sure how to fix this. Any pointers would be appreciated.

Thanks,

Jeff

Your “class” column is an integer and it needs to be a string.

Converting the column from integer to string fixed the problem. Thank you.
