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)
