  Given `tensor`, this operation returns a tensor that has the same values
  as `tensor` with shape `shape`.
  -If one component of `shape` is the special value -1, the size of that dimension

  +The `shape` must be 1-D and the operation returns a tensor with shape
  `shape` filled with the values of `tensor`. In this case, the number of elements
  implied by `shape` must be the same as the number of elements in `tensor`.
  +It is an error if `shape` is not 1-D.
