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 from_json_content(
      cls, value: feature_pb2.TensorFeature
  ) -> "Scalar":
      return cls(dtype=feature_lib.dtype_from_str(value.dtype))
