Instantiates an all-ones variable and returns it.
tf.keras.backend.ones(
shape, dtype=None, name=None
)
shape
: Tuple of integers, shape of returned Keras variable.dtype
: String, data type of returned Keras variable.name
: String, name of returned Keras variable.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.
>>> 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)
