xgb.load

Load xgboost model from binary file

Load xgboost model from the binary model file.

Usage

xgb.load(modelfile)

Details

The input file is expected to contain a model saved in an xgboost-internal binary format using either xgb.save or cb.save.model in R, or using some appropriate methods from other xgboost interfaces. E.g., a model trained in Python and saved from there in xgboost format, could be loaded from R.

Note: a model saved as an R-object, has to be loaded using corresponding R-methods, not xgb.load.
