Codeless Deep Learning LSTM example not working

Hi,

I am running KNIME Analytics 5.4.4. I teach a deep learning course and have adopted “Codeless Deep Learning” by Melcher and Silipo to support my classes. I’ve imported the LSTM example from chapter 6 (01TSAwithLSTMNetwork_Training) using the link provided in the book and made no changes in the workflow. However, when I run it, it doesn’t work as described in the chapter. The LSTM network predictions are all 0.

I would really appreciate any help on this matter.
