tf.keras.backend.ones_like

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

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

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

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: python >>> from keras import backend as K >>> kvar = K.variable(np.random.random((2,3))) >>> kvar_ones = K.ones_like(kvar) >>> K.eval(kvar_ones) array([[ 1., 1., 1.], [ 1., 1., 1.]], dtype=float32)
