If you are loading a serialized model (like pickle in Python) generated by older
XGBoost, please export the model by calling Booster.save_model from that version
first, then load it back in current version. There’s a simple script for helping
the process. See:
https://xgboost.readthedocs.io/en/latest/tutorials/saving_model.html
for reference to the script, and more details about differences between saving model and
serializing.
