class SparseMatrixOrderingAMD(Primitive):
r"""
Computes the Approximate Minimum Degree (AMD) ordering of `input`.
Computes the Approximate Minimum Degree (AMD) ordering for a sparse matrix.
The returned permutation may be used to permute the rows and columns of the given sparse matrix.
This typically results in permuted sparse matrix's sparse Cholesky (or other decompositions) in
having fewer zero fill-in compared to decomposition of the original matrix.
The input sparse matrix may have rank 2 or rank 3. The output Tensor, representing would then have
rank 1 or 2 respectively, with the same batch shape as the `input`.
Each component of the input sparse matrix must represent a square symmetric matrix; only the lower
triangular part of the matrix is read. The values of the sparse matrix does not affect the returned
permutation, only the sparsity pattern of the sparse matrix is used. Hence, a single AMD ordering may
be reused for the Cholesky decompositions of sparse matrices with the same sparsity pattern but
with possibly different values.
Each batch component of the output permutation represents a permutation of `N` elements, where
the input sparse matrix components each have `N` rows. That is, the component contains each of the
integers :math:`{0, .. N-1}` exactly once. The `i`th element represents the row index that the `i`th
row maps to.
Inputs:
- **x_dense_shape** (Tensor) - A 1-D Tensor. It represents the dense form shape of
the input CSR sparse matrix x, the shape of which should be :math:`(2,)` or :math:`(3,)`.
- **x_batch_pointers** (Tensor) - A 1-D Tensor. Supposing the input CSR sparse matrix x is of
batch size `n`, it should have shape :math:`(n+1,)`, while the `i`-th element of which stores
acummulated counts of nonzero values of the first `i - 1` batches.
- **x_row_pointers** (Tensor) - A 1-D Tensor. Supposing the input CSR sparse matrix x is of
batch size `n` and row number `m`, it can be divided into `n` parts, each part of length
`m + 1`. The `i`-th element of each :math:`(m+1,)` vector stores acummulated counts of
nonzero values of the first `i - 1` rows in the corresponding batch.
- **x_col_indices** (Tensor) - A 1-D Tensor. It represents column indices of the nonzero values
in the input CSR sparse matrix x.
- **x_values** (Tensor) - A 1-D Tensor. It represents all the nonzero values in the
input CSR sparse matrix x.
Outputs:

If there are n batch within input sparse matrix, the shape is :math:`(n,)`.

"""
Generates sparse cross from a list of sparse and dense tensors.
Args:
hashed_output (bool): If true, returns the hash of the cross instead of the string. This will allow us
avoiding string manipulations.
num_buckets (int): An int that is >= 0. It is used if "hashed_output" is true.output = hashed_value%num_buckets
if num_buckets > 0 else "hashed_value".
hash_key (int): Specify the hash_key that will be used by the "FingerprintCat64" function to combine the
crosses fingerprints.
out_type (mindspore.dtype): The output data type. Defaults to "int64".
internal_type (mindspore.dtype): An type int64.
Inputs:
- **indices** (list(Tensor)) - A list of Tensor objects with type int64. 2-D.
Indices of each input SparseTensor.

1-D. Shapes of each SparseTensor.
- **dense_inputs** (list(Tensor)) - A list of Tensor objects with types from: int64.
2-D. Columns represented by dense Tensor.
Outputs:

- **output_values** (Tensor) - A Tensor of type "out_type". 1-D.
Non-empty values of the concatenated or hashed SparseTensor.
- **output_shape** (Tensor) - A Tensor of type int64. 1-D. Shape of the concatenated SparseTensor.
Raises:

Converts a RaggedTensor into a SparseTensor with the same values.
Args:
Tsplits(mindspore.dtype): A required attribute, the type of the `rt_nested_splits`. Default: `int64`.
Inputs:
- **rt_nested_splits** (list(Tensor)) - A list of at least 1 `Tensor` objects with the same
type in: `int64`, `int32`. The row_splits for the RaggedTensor.
Ragged splits is in ascending order, first value of splits must be 0 and final value of splits
must equal with the length of `rt_dense_values`.
- **rt_dense_values** (Tensor) - A `Tensor`. The flat_values for the RaggedTensor. The rank of values
must more than 0.
Outputs:
- **sparse_indices** (Tensor) - A `Tensor` of type int64. Contains the indices of the output
sparse tensor.
