  r"""Decodes a `variant` Tensor into a `RaggedTensor`.

  Decodes the given `variant` Tensor and returns a `RaggedTensor`. The input
  could be a scalar, meaning it encodes a single `RaggedTensor` with ragged_rank
  `output_ragged_rank`. It could also have an arbitrary rank, in which case each
  element is decoded into a `RaggedTensor` with ragged_rank `input_ragged_rank`
  and these are then stacked according to the input shape to output a single
  `RaggedTensor` with ragged_rank `output_ragged_rank`. Each `variant` element in
  the input Tensor is decoded by retrieving from the element a 1-D `variant`
  Tensor with `input_ragged_rank + 1` Tensors, corresponding to the splits and
  values of the decoded `RaggedTensor`. If `input_ragged_rank` is -1, then it is
  inferred as `output_ragged_rank` - `rank(encoded_ragged)`. See
  `RaggedTensorToVariant` for the corresponding encoding logic.

  Args:
    encoded_ragged: A `Tensor` of type `variant`.
      A `variant` Tensor containing encoded `RaggedTensor`s.
    input_ragged_rank: An `int` that is `>= -1`.
      The ragged rank of each encoded `RaggedTensor` component in the input. If set to
      -1, this is inferred as `output_ragged_rank` - `rank(encoded_ragged)`
    output_ragged_rank: An `int` that is `>= 1`.
      The expected ragged rank of the output `RaggedTensor`. The following must hold:
      `output_ragged_rank = rank(encoded_ragged) + input_ragged_rank`.
    Tvalues: A `tf.DType`.
    Tsplits: A `tf.DType` from: `tf.int32, tf.int64`.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (output_nested_splits, output_dense_values).

    output_nested_splits: A list of `output_ragged_rank` `Tensor` objects with type `Tsplits`.
    output_dense_values: A `Tensor` of type `Tvalues`.
