Hello,
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…?
