tf.keras.backend.zeros_like(
x,
dtype=None,
name=None
)
Defined in tensorflow/python/keras/backend.py.
Instantiates an all-zeros variable of the same shape as another tensor.
Arguments:
x: Keras variable or Keras 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 zeros.
Example:
python
>>> from 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)
