#' @title Make a LightGBM object serializable by keeping raw bytes
|
|
#' @description 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 \code{saveRDS} and \code{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.
