Hi,

I’m trying to export ‘XGBOOST Tree Ensemble’ as PMML model. But PMML writer is not allowing me to export the model.

Are there any other ways to export or save XGBoost models using KNIME?

Thanks,  
Zeitung

You could use the model writer like in this example

Hi All,

I’m not sure as to whether the ‘Model Writer’ node actually writes to PMML or not? Is anybody able to clarify this?

Kind regards,  
Michael

No it does not. The model writer does write a broad variety of models into a ZIP file. PMML is a separate case.
