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:

as well as the input table.

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.
