(Indeed, as in your code the group isn't even passed to the prediction. After training, it's just an ordinary GBM.) The interpretation (and hence also scoring the model on the test set) should use these …
WebStep 1: Diving in, RTFM. Since XGBoost is an open-source we started by reading the implementation of DMatrix in the XGBoost Python package. We first looked at the constructor – according to the documentation, it is able to get a variety of data types among them NumPy and convert them to the DMatrix data type.
