Instantiates an all-ones variable and returns it.

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.


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