ones_like(
    x,
    dtype=None,
    name=None
)

Defined in tensorflow/contrib/keras/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:

>>> 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)
