class_docstr: The :class:`Dropout` class is a noise layer which randomly set some
  activations to zero according to a keeping probability.
  
  Parameters
  ----------
  keep : float
      The keeping probability.
      The lower the probability it is, the more activations are set to zero.
  seed : int or None
      The seed for random dropout.
  name : None or str
      A unique layer name.
code: def build(self, inputs_shape=None):
      pass
