Deep Learning 1.0 Error when testing regression-style problems

edited October 2020 in Help
When training a model on a regression data, i.e. with numerical label (such as "sea shells ages"), the model trains fine with training data only. When we connect the test port (e.g. by splitting data into training and testing partition), the following error is generated:

Oct 21, 2020 9:06:59 PM WARNING: Example set has no nominal label: using shuffled partition instead of stratified partition
Oct 21, 2020 9:06:59 PM SEVERE: Process failed: operator cannot be executed (The method getNominalMapping() is not supported by numerical attributes! You probably tried to execute an operator on a numerical data which is only able to handle nominal values. You could use one of the discretization operators before this application.). Check the log messages...

When we train the model on a classification data, i.e. with a nominal label (such as "iris flowers"), the process completes without any problems.
I am running those examples with Deep Learning extension 1.0, on RapidMiner 9.8, with CPU-OpenBLAS and with GPU-CUDA (CUDA 10.1), on Ubuntu 18.04 and Ubuntu 20.04.

Here is a modified "sea shells ages" sample process (the "Deep Learning" operator has not been altered).

    @pschlunder I wonder if this issue is in any way related to my previous DL extension problem, this one is easily reproduceable though.
