Instantiates an all-zeros variable of the same shape as another tensor.
tf.keras.backend.zeros_like(
x, dtype=None, name=None
)
Arguments |
x
|
Keras variable or Keras tensor.
|
dtype
|
dtype of returned Keras variable.
None uses the dtype of x .
|
name
|
name for the variable to create.
|
Returns |
A Keras variable with the shape of x filled with zeros.
|
Example:
from tensorflow.keras import backend as K
kvar = K.variable(np.random.random((2,3)))
kvar_zeros = K.zeros_like(kvar)
K.eval(kvar_zeros)
array([[ 0., 0., 0.], [ 0., 0., 0.]], dtype=float32)
