XGBRegression gives constant difference

[ilkot]

Hello,
thanks for the code, helped a lot!
I tried XGBRegressor but it constantly less around 0.5 than python predictions

I checked dump_raw.txt vs xgb_regressor.cpp numbers have same decimals, so it shouldn't be a problem

Do you have any idea why?

Have you find the problem?
I met the same situation as yours.
and i can't find any useful information from the source code.

@DotaSF unfortunately not, I just add 0.5 constantly.

The method dump_model specify that it can't be loaded back into a model. See below.
Maybe this git is outdated.

(method) def dump_model(
fout: str | PathLike,
fmap: str | PathLike = '',
with_stats: bool = False,
dump_format: str = "text"
) -> None
Dump model into a text or JSON file. Unlike save_model, the output format is primarily used for visualization or interpretation, hence it's more human readable but cannot be loaded back to XGBoost.
