XGBoost Tree Ensemble Learner ERROR

Hello,

I am using KNIME version 5.3.0. While trying to execute the node “XGBoost Tree Ensemble Learner” (Node #2660), I get an error with the following description:

“ERROR KNIME-Worker-155-XGBoost Tree Ensemble Learner 3:2660 Node Execute failed: [01:00:37] /workspace/src/Learner.cc:1253: Check failed: Learner_model_param_.num_feature == p_fmat->Info().num.col (7 vs. 6) : Number of columns does not match number of features in booster”.

Does anyone know what may be the problem?

Best,
Karla.

Hi Karla,
Welcome to the KNIME Forum! Would you be willing to share your workflow (maybe with dummy data) so we can try to reproduce the issue?
Kind regards,
Alexander
