*@brief Converts a RaggedTensor into a SparseTensor with the same values . \n

*@par Inputs:
*Two inputs, including:
*@li rt_nested_splits: A list of at least 1 Tensor objects with the same type
in: int32, int64. The row_splits for the RaggedTensor. It's a dynamic input.
*@li rt_dense_values: A Tensor. The flat_values for the RaggedTensor
Must be one of the following types: bool, int8, int16, uint16, int32,
int64, double, float, float16 . \n

*@par Attributes:
*@li RAGGED_RANK: the dynamic of input rt_nested_splits with type int.
*@li Tsplits: A required attribute, the type is int64 . \n

*@par Outputs:
*@li sparse_indices: A Tensor of type int64.
*@li sparse_values: A Tensor. Has the same type as rt_dense_values.
*@li sparse_dense_shape: A Tensor of type int64 . \n

*@par Third-party framework compatibility
* Compatible with TensorFlow operator RaggedTensorToSparse.

*@brief Create a dense tensor from a ragged tensor, possibly altering its shape . \n

*@par Inputs:
*@li shape:A `Tensor`. Must be one of the following types: `int64`, `int32`.
*@li values:A 1D tensor representing the values of the ragged tensor.
*@li default_value:A `Tensor`. Must have the same type as `values`.
*@li row_partition_tensors:A list of at least 1 `Tensor` objects with the same
type in: `int64`, `int32` . It's a dynamic input.\n

*@par Attributes:
*@li num_row_partition_tensors:Numbers of row partition tensors.
*@li 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" . \n

*@par Outputs:
*result: A `Tensor`. Has the same type as `values`.
