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:

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)
