ML Multiclass Classifier Tester Error


Solution exception:Exception has been thrown by the target of an invocation.

The data is normalized (0 to 1) and the outputs (label) are 12 categories as hot encode.

I’m getting that error despites multiple tries, using different data and how the data has been created with either “Create Data Set” or as in the image with “Split Data”. I also try my replacing the paths to a simplified and ascendant way. I did try the same setup of how to create the data, trainer, model and tester and I get no errors, as the examples in the LunchBox Documentation | Proving Ground Apps

Any idea why I’m getting the error? Thank you in advance!
