tf.keras.activations.deserialize

Returns activation function given a string identifier.

tf.keras.activations.deserialize(
    name, custom_objects=None, use_legacy_format=False
)

Args
name	The name of the activation function.
custom_objects	Optional {function_name: function_obj} dictionary listing user-provided activation functions.
use_legacy_format	Boolean, whether to use the legacy format for deserialization. Defaults to False.

Returns
Corresponding activation function.

Example:

tf.keras.activations.deserialize('linear')
 <function linear at 0x1239596a8>
tf.keras.activations.deserialize('sigmoid')
 <function sigmoid at 0x123959510>
tf.keras.activations.deserialize('abcd')
Traceback (most recent call last):

ValueError: Unknown activation function 'abcd' cannot be deserialized.

Raises
ValueError	Unknown activation function if the input string does not denote any defined Tensorflow activation function.
