tf.compat.v1.keras.backend.ones, `tf.compat.v2.keras.backend.ones`

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:

from keras import backend as K
kvar = K.ones((3,4))
K.eval(kvar)
array([[ 1.,  1.,  1.,  1.],
       [ 1.,  1.,  1.,  1.],
       [ 1.,  1.,  1.,  1.]], dtype=float32)
