tf.keras.backend.ones

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

Defined in tensorflow/python/keras/_impl/keras/backend.py.

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: python >>> 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)
