Save/Load models using HDF5 files
save_model_hdf5(object, filepath, overwrite = TRUE, include_optimizer = TRUE) load_model_hdf5(filepath, custom_objects = NULL, compile = TRUE)
Model object to save
Overwrite existing file if necessary
Mapping class names (or function names) of custom (non-Keras) objects to class/functions (for example, custom metrics or custom loss functions). This mapping can be done with the dict() function of reticulate.
Whether to compile the model after loading.
The following components of the model are saved:
The model architecture, allowing to re-instantiate the model.
The model weights.
The state of the optimizer, allowing to resume training exactly where you left off. This allows you to save the entirety of the state of a model in a single file.
Saved models can be reinstantiated via
load_model_hdf5(). The model returned by
load_model_hdf5() is a compiled model ready to be used (unless the saved model
was never compiled in the first place or
compile = FALSE is specified).
As an alternative to providing the
custom_objects argument, you can
execute the definition and persistence of your model using the
serialize_model() function enables saving Keras models to
R objects that can be persisted across R sessions.
