tf.keras.backend.ones

View source on GitHub

Instantiates an all-ones variable and returns it.

tf.keras.backend.ones(
    shape, dtype=None, name=None
)

Arguments:

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)
