Make a LightGBM object serializable by keeping raw bytes

Source: R/lgb.make_serializable.R

If a LightGBM model object was produced with argument `serializable=FALSE`, the R object will not be serializable (e.g. cannot save and load with saveRDS and readRDS) as it will lack the raw bytes needed to reconstruct its underlying C++ object. This function can be used to forcibly produce those serialized raw bytes and make the object serializable. Note that the object will be modified in-place.

New in version 4.0.0

lgb.make_serializable(model)

Arguments

model

lgb.Booster object which was produced with `serializable=FALSE`.

Value

lgb.Booster (the same `model` object that was passed as input, as invisible).
