tf.keras.backend.ones

View source on GitHub

Instantiates an all-ones variable and returns it.

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)
