tf.compat.v1.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)`
