def lecun_uniform(seed=None):
      """LeCun uniform initializer.

      It draws samples from a uniform distribution within [-limit, limit]
      where `limit` is `sqrt(3 / fan_in)`
      where `fan_in` is the number of input units in the weight tensor.

      Arguments:
          seed: A Python integer. Used to seed the random generator.

      Returns:
          An initializer.
