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

name The name of the activation function.
custom_objects Optional {function_name: function_obj} dictionary listing user-provided activation functions.

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')
