def zeros_like(x, name=None):
'''Instantiates an all-zeros Keras variable
of the same shape as another Keras variable or tensor and returns it.
# Arguments
x: Keras variable or Keras tensor.
# Returns
A Keras variable, filled with `0.0`.
# 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)
'''
return tf.zeros_like(x, name=name)
