save_load_rda: Save and Load .rda Files with Conversion to Raw and Keras Models

Description

Save and load .rda files with conversion to objects of class raw (for save_gnn()) or "keras.engine.training.Model" (for load_gnn()).

Usage

save_gnn(..., file, name = NULL)
load_gnn(file)

Value

save_gnn()

nothing (generates an .rda by side-effect).

load_gnn()

the loaded object(s). Those of class "gnn_GNN" are converted with as.keras() before they are returned; this also applies to a component of a loaded object of class list.

Arguments

...

objects to be saved in file (under the provided names if name was provided). Those objects which are of class "gnn_GNN" are converted with as.raw() before they are saved.

file

file name; see the underlying save() and load().

name

character (vector) of name(s) under which the objects in ... are to be saved in file. If NULL, the names of the objects provided by ... are taken as name.

Examples

if(TensorFlow_available()) { # rather restrictive (due to R-Forge, winbuilder)
library(gnn) # for being standalone

file <- tempfile("foo", fileext = ".rda")
GMMN1 <- FNN()
save_gnn(GMMN1, file = file) # converts GMMN via as.raw()
GMMN2 <- load_gnn(file) # converts loaded object via as.keras()
stopifnot(is.GNN(GMMN2), inherits(GMMN2[["model"]], "keras.engine.training.Model"))
rm(GMMN1, GMMN2) # clean-up
stopifnot(file.remove(file))
