def encode_proto(sizes, values, field_names, message_type, descriptor_source="local://", name=None):
  r"""The op serializes protobuf messages provided in the input tensors.

  The types of the tensors in `values` must match the schema for the
  fields specified in `field_names`. All the tensors in `values` must
  have a common shape prefix, *batch_shape*.

  The `sizes` tensor specifies repeat counts for each field.  The repeat
  count (last dimension) of a each tensor in `values` must be greater
  than or equal to corresponding repeat count in `sizes`.

  A `message_type` name must be provided to give context for the field
  names. The actual message descriptor can be looked up either in the
  linked-in descriptor pool or a filename provided by the caller using
  the `descriptor_source` attribute.

  The `descriptor_source` attribute selects a source of protocol
  descriptors to consult when looking up `message_type`. This may be a
  filename containing a serialized `FileDescriptorSet` message,
  or the special value `local://`, in which case only descriptors linked
  into the code will be searched; the filename can be on any filesystem
  accessible to TensorFlow.

  You can build a `descriptor_source` file using the `--descriptor_set_out`
  and `--include_imports` options to the protocol compiler `protoc`.

  The `local://` database only covers descriptors linked into the
  code via C++ libraries, not Python imports. You can link in a proto descriptor
  by creating a cc_library target with alwayslink=1.

  There are a few special cases in the value mapping:

  Submessage and group fields must be pre-serialized as TensorFlow strings.

  TensorFlow lacks support for unsigned int64s, so they must be
  represented as `tf.int64` with the same twos-complement bit pattern
  (the obvious way).

  Unsigned int32 values can be represented exactly with `tf.int64`, or
  with sign wrapping if the input is of type `tf.int32`.

  Args:
    sizes: A `Tensor` of type `int32`.
      Tensor of int32 with shape `[batch_shape, len(field_names)]`.
    values: A list of `Tensor` objects.
      List of tensors containing values for the corresponding field.
    field_names: A list of `strings`.
      List of strings containing proto field names.
    message_type: A `string`. Name of the proto message type to decode.
    descriptor_source: An optional `string`. Defaults to `"local://"`.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `string`.
