Saving Keras Models

KNIME Extensions
1

Hi,

I created and trained a keras model (backend: tensorflow) using the newly built-in KNIME nodes. How do I save such a model? I am missing a DL Keras Network Writer" node or something similar.

Thanks in advance!

I found the answer to my own question: The Model Writer node.

Great! We plan to add a Keras Writer as well, which then gives you the opportunity to write native Keras models. Let us know if you run into any problems.

Best,
