Model objects are external references to Keras objects which cannot be saved and restored across R sessions. The serialize_model() and unserialize_model() functions provide facilities to convert Keras models to R objects for persistence within R data files.

serialize_model(model, include_optimizer = TRUE)

unserialize_model(model, custom_objects = NULL, compile = TRUE)

Arguments

model

Keras model or R "raw" object containing serialized Keras model.

include_optimizer

If TRUE, save optimizer's state.

custom_objects

Mapping class names (or function names) of custom (non-Keras) objects to class/functions (for example, custom metrics or custom loss functions).

compile

Whether to compile the model after loading.

Value

serialize_model() returns an R "raw" object containing an hdf5 version of the Keras model. unserialize_model() returns a Keras model.

Note

The save_model_hdf5() function enables saving Keras models to external hdf5 files.
