Find the solution to a large, sparse, linear system of equations. The function solves ``Ax = b``. Given two-dimensional matrix ``A`` is decomposed into ``L * L^*``. Args: A (cupy.ndarray or cupyx.scipy.sparse.csr_matrix): The input matrix with dimension ``(N, N)``. Must be positive-definite input matrix. Only symmetric real matrix is supported currently. b (cupy.ndarray): Right-hand side vector. Returns: ret (cupy.ndarray): The solution vector ``x``. r)cusolverz+b must be 1-d array whose size is same as Afdg?)dtype) cupy_backends.cuda.libsrrisspmatrix_csr csr_matrixr_assert_stacked_square_assert_cupy_arrayshapendimlen ValueErrorr numpy promote_typesrget_cusolver_sp_handlennzcupyemptyint32 scsrlsvchol dcsrlsvchol_descr descriptordataptrindptrindicesctypesastypefloat64) Abrmr handlertolreorderx singularity csrlsvcholr.W/home/ubuntu/veenaModal/venv/lib/python3.10/site-packages/cupyx/linalg/sparse/_solve.pylschol s6        r0) rr cupy.cudar cupy.linalgr cupyx.scipyrr0r.r.r.r/s
