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:
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)
