tf.keras.backend.ones
Instantiates an all-ones variable and returns it.
tf.keras.backend.ones(
shape, dtype=None, name=None
)
Arguments |
shape
|
Tuple of integers, shape of returned Keras variable.
|
dtype
|
String, data type of returned Keras variable.
|
name
|
String, name of returned Keras variable.
|
Returns |
A Keras variable, filled with 1.0 .
Note that if shape was symbolic, we cannot return a variable,
and will return a dynamically-shaped tensor instead.

Example:
kvar = tf.keras.backend.ones((3,4))
tf.keras.backend.eval(kvar)
array([[1., 1., 1., 1.],
[1., 1., 1., 1.],
[1., 1., 1., 1.]], dtype=float32)
