class_docstr: A scalar feature of a particular dtype (e.g., np.int64 or np.float).
  
  Equivalent to `tfds.features.Tensor(shape=(), dtype=dtype)`.
code: def __init__(
      self,
      dtype: type_utils.TfdsDType,
      *,
      doc: feature_lib.DocArg = None,
  ):
      super().__init__(shape=(), dtype=dtype, doc=doc)
