xgb.load
From xgboost v1.3.2.1
by Tong He
Load xgboost model from binary file
Load xgboost model from the binary model file.
Usage
xgb.load(modelfile)
Arguments
- modelfile
the name of the binary input file.
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
.
Value
An object of xgb.Booster
class.
