Function zeros_like

tensorflow/python/keras/backend.py:1373–1396

Instantiates an all-zeros variable of the same shape as another tensor. 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 wit

(x, dtype=None, name=None)

      A Keras variable with the shape of `x` filled with zeros.

  Example:

  ```python

  kvar_zeros = K.zeros_like(kvar)
  K.eval(kvar_zeros)
