@ParkJunYong you can pickle models from the python nodes

The other model types to use with external programs are H2O.ai MOJO (I would recommend that it works across programs like R and Python and operating systems)

Next one would be PMML which has been built for this but faces challenges when using it in real life.

Underneath there has to be a model that the package that you used can read([KNIME ML to Python - #2 by mlauber71](https://forum.knime.com/t/knime-ml-to-python/44220/2) ). If you want to use it with Jupyter notebooks this has to work in both environments. You could try and store a model just as pickel and use knime as interface for some python models. Here are examples from several versions of knime and python: There are other frameworks you could use. Knime started to generic…
