tf.keras.activations.get(
    identifier
)

Arguments:

identifier: Function or string

Returns:

Activation function denoted by input: - Linear activation function if input is None. - Function corresponding to the input string or input function.

For example:

>>> tf.keras.activations.get('softmax')
 <function softmax at 0x1222a3d90>
>>> tf.keras.activations.get(tf.keras.activations.softmax)
 <function softmax at 0x1222a3d90>
>>> tf.keras.activations.get(None)
 <function linear at 0x1239596a8>
>>> tf.keras.activations.get(abs)
 <built-in function abs>
>>> tf.keras.activations.get('abcd')
Traceback (most recent call last):
...
ValueError: Unknown activation function:abcd

Raises:

ValueError: Input is an unknown function or string, i.e., the input does not denote any defined function.
