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)
