KNIME ML to Python

[mlauber71]

@BrBr two options would be to use H2O.ai models or PMML

Will Knime support saving or loading the model in pickle format?? I think the python script only support jython code as per documentation can someone tell me whether it will also support python code.

Pickle is not a model or data format by itself but it would ‘wrap’ a Python object and store it to be brought back later. If you want to use models between KNIME and Python you should look for example think about using PMML - mostly I have used MOJO model files from H2O.ai which can easily be shared between KNIME and Python (or R) - if you use the correct MOJO version (which is not so obvious, unfortunately) - eg: KNIME 4.1* <-> H2O 3.2* (MOJO version 1.3) KNIME 4.2* <-> H2O 3.3* (MOJO versio…

Decision tree learner seems to be overfitting

@akhtarameen you can import H2O.ai MOJO models into KNIME, R, Python and Spark (and back). That is why I like to use this format - for example I can develop a model on an R machine and then deploy it on a big data cluster. This collection actually contains Jupiter notebook that basically does the same thing. So you might want to try that. There you might also see how to use relative paths in a notebook.
