The `identifier` may be the string name of a initializers function or class (case-sensitively). >>> identifier = 'Ones' >>> tf.keras.initializers.deserialize(identifier) <...keras.initializers.initializers_v2.Ones...> You can also specify `config` of the initializer to this function by passing dict containing `class_name` and `config` as an identifier. Also note that the `class_name` must map to a `Initializer` class. >>> cfg = {'class_name': 'Ones', 'config': {}} >>> tf.keras.initializers.deserialize(cfg) <...keras.initializers.initializers_v2.Ones...> In the case that the `identifier` is a class, this method will return a new instance of the class by its constructor. Args: identifier: String or dict that contains the initializer name or configurations. Returns: Initializer instance base on the input identifier.
