Problem with DL Python Network

Do you know what it can be?

Hi,
do other Python Deep Learning nodes work? Can you have a look at the end of the KNIME Log (View -> Open KNIME Log) and let me know what you see there?
Kind regards
Alexander

Hi,
can you also share your Python code inside the DL Python Network Creator node? Maybe the object you are trying to return cannot be serialized?
Kind regards

I use:

Perfect, thank you! The workflow was created by @bwilhelm, maybe he can shed some light on this problem?
