tf.keras.models.load_model

Loads a model saved via model.save().

tf.keras.models.load_model(
    filepath, custom_objects=None, compile=True, options=None
)

Usage:

model = tf.keras.Sequential([
    tf.keras.layers.Dense(5, input_shape=(3,)),
    tf.keras.layers.Softmax()])
model.save('/tmp/model')
loaded_model = tf.keras.models.load_model('/tmp/model')
x = tf.random.uniform((10, 3))
assert np.allclose(model.predict(x), loaded_model.predict(x))

Note that the model weights may have different scoped names after being loaded. Scoped names include the model/layer names, such as "dense_1/kernel:0". It is recommended that you use the layer properties to access specific variables, e.g. model.get_layer("dense_1").kernel.

filepath One of the following:

  • String or pathlib.Path object, path to the saved model
  • h5py.File object from which to load the model
custom_objects Optional dictionary mapping names (strings) to custom classes or functions to be considered during deserialization.
compile Boolean, whether to compile the model after loading.
options Optional tf.saved_model.LoadOptions object that specifies options for loading from SavedModel.

A Keras model instance. If the original model was compiled, and saved with the optimizer, then the returned model will be compiled. Otherwise, the model will be left uncompiled. In the case that an uncompiled model is returned, a warning is displayed if the compile argument is set to True.

ImportError if loading from an hdf5 file and h5py is not available.
IOError In case of an invalid savefile.
