  A `TensorProto`. Depending on the type, it may contain data in the
  "tensor_content" attribute, which is not directly useful to Python programs.
  To access the values you should convert the proto back to a numpy ndarray
  - with `tensor_util.MakeNdarray(proto)`.
  + with `tf.make_ndarray(proto)`.
  If `values` is a `TensorProto`, it is immediately returned; `dtype` and
  `shape` are ignored.
