Execution fails for node XGBoost Tree Ensemble Learner (Regression)


While trying to execute the node “XGBoost Tree Ensemble Learner (Regression)”, I get an error with the following description: “Execute failed: java.lang.NoClassDefFoundError: org/knime/core/data/convert/java/DataCellToDoubleConverter”.

Does anyone know what may be the problem?
I have installed the XGBoost extensions offline via the full zip file. It is my first time installing extensions this way, so maybe I need to install extra features to solve the problem…?


Hi @Sagie_Finiti,

do you have the same problem executing this xgboost regression example? If yes, could you share the versions of KNIME analytics platform and XGBoost extension that you have?
