Hi all,
I am currently struggling with nested looping in knime. I am attempting to loop through a folder of files through a file reader, then use each input from this first loop to train a decision tree, then generate predictions for every file in that same list. I am only interested in saving the output of the prediction engine, not of the learner itself.
The problem I run into is that when I try to create a second loop within the first, I run into the error displayed below.
Has anyone else run into this?
Thanks,
Chris
