  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 `>= 0`.
      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: An optional `tf.DType` from: `tf.int32, tf.int64`. Defaults to `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`.

def ragged_tensor_to_tensor(shape, values, default_value, row_partition_tensors, row_partition_types, name=None):
  r"""Create a dense tensor from a ragged tensor, possibly altering its shape.


  The `ragged_to_dense` op creates a dense tensor from a list of row partition

  tensors, a value vector, and default values. If the shape is unspecified, the

  minimal shape required to contain all the elements in the ragged tensor (the

  natural shape) will be used. If some dimensions are left unspecified, then the

  size of the natural shape is used in that dimension.

  

  The default_value will be broadcast to the output shape. After that, the values

  from the ragged tensor overwrite the default values. Note that the default_value

  must have less dimensions than the value.

  

  The row partition tensors are in the order of the dimensions.

  At present, the types can be:

  * "ROW_SPLITS": the row_splits tensor from the ragged tensor.

  * "VALUE_ROWIDS": the value_rowids tensor from the ragged tensor.

  * "FIRST_DIM_SIZE": if value_rowids is used for the first dimension, then it

    is preceded by "FIRST_DIM_SIZE".

  Args:
    shape: A `Tensor`. Must be one of the following types: `int64`, `int32`.
      The desired shape of the output tensor. If left unspecified (empty),

      the minimal shape required to contain all the elements in the ragged tensor

      (the natural shape) will be used. If some dimensions are left unspecified, then

      the size of the natural shape is used in that dimension.

      

      Note that dense dimensions cannot be modified by the shape argument. Trying to

      change the size of a dense dimension will cause the op to fail.

      Examples:

      natural shape: [4, 5, 6]

      shape: -1

      output shape: [4, 5, 6]

      

      natural shape: [4, 5, 6]

      shape: [3, -1, 2]

      output shape: [3, 5, 2]

      

      natural shape: [4, 5, 6]

      shape: [3, 7, 2]

      output shape: [3, 7, 2]
    values: A `Tensor`.
      A 1D tensor representing the values of the ragged tensor.
    default_value: A `Tensor`. Must have the same type as `values`.
      The default_value when the shape is larger than the ragged tensor. The

      default_value is broadcast until it is the shape of the output tensor, and

      then overwritten by values in the ragged tensor. The default value must be

      compatible with this broadcast operation, and must have fewer dimensions than

      the value tensor.
    row_partition_tensors: A list of at least 1 `Tensor` objects with the same type in: `int64`, `int32`.
    row_partition_types: A list of `strings`.
      The types of the row partition tensors. At present, these can be:

      * "ROW_SPLITS": the row_splits tensor from the ragged tensor.

      * "VALUE_ROWIDS": the value_rowids tensor from the ragged tensor.

      * "FIRST_DIM_SIZE": if value_rowids is used for the first dimension, then it

        is preceeded by "FIRST_DIM_SIZE".

      The tensors are in the order of the dimensions.
    name: A name for the operation (optional).

  Returns:
    A `Tensor`. Has the same type as `values`.

def ragged_tensor_to_variant_gradient(encoded_ragged_grad, row_splits, dense_values_shape, Tvalues, name=None):
  r"""Helper used to compute the gradient for `RaggedTensorToVariant`.


  Computes the gradient for the dense_values input to the RaggedTensorToVariant

  op, given the variant-encoded ragged gradients of the outputs, along with

  the outer row-splits and the shape of the dense-values that were provided as

  inputs to the RaggedTensorToVariant op.

  Args:
    encoded_ragged_grad: A `Tensor` of type `variant`.
      A `variant` Tensor containing encoded `RaggedTensor` gradients.
    row_splits: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      Outermost row-splits that were used as input to the RaggedTensorToVariant op.
    dense_values_shape: A `Tensor` of type `int32`.
      Shape of the dense_values that was used as an input to the

      RaggedTensorToVariant op.
    Tvalues: A `tf.DType`.
    name: A name for the operation (optional).

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