Save xgboost model to binary file
Save xgboost model to a file in binary format.
xgb.save(model, fname)
model |
model object of |
fname |
name of the file to write. |
Note: a model can also be saved as an R-object (e.g., by using readRDS
or save). However, it would then only be compatible with R, and
corresponding R-methods would need to be used to load it. Moreover, persisting the model with
readRDS or save) will cause compatibility problems in
future versions of XGBoost. Consult a-compatibility-note-for-saveRDS-save to learn
how to persist models in a future-proof way, i.e. to make the model accessible in future
releases of XGBoost.
