tf.keras.backend.ones

TensorFlow 1 version View source on GitHub

Instantiates an all-ones variable and returns it.

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)
