TensorFlow 1 version View source on GitHub

Instantiates an all-ones variable of the same shape as another tensor.

tf.keras.backend.ones_like(
    x,
    dtype=None,
    name=None
)

Arguments:

  • x: Keras variable or tensor.
  • dtype: String, dtype of returned Keras variable. None uses the dtype of x.
  • name: String, name for the variable to create.

Returns:

A Keras variable with the shape of x filled with ones.

Example:

>>> kvar = tf.keras.backend.variable(np.random.random((2,3)))
>>> kvar_ones = tf.keras.backend.ones_like(kvar)
>>> tf.keras.backend.eval(kvar_ones)
array([[1.,  1.,  1.],
       [1.,  1.,  1.]], dtype=float32)
