In modeltime.gluonts: 'GluonTS' Deep Learning

Description

Usage

save_gluonts_model(object, path, overwrite = FALSE)

load_gluonts_model(path)

Arguments

object	A fitted model object
path	A directory to store the GluonTS model files
overwrite	Whether or not to allow overwriting a GluonTS model's directory. Default: FALSE.
