torch.hspmm
torch.hspmm(mat1, mat2, *, out=None) -> Tensor
Performs a matrix multiplication of a sparse COO matrix "mat1" and
   a strided matrix "mat2". The result is a (1 + 1)-dimensional hybrid
   COO matrix.
Parameters:
      * mat1 (Tensor) -- the first sparse matrix to be matrix
        multiplied
  * **mat2** (*Tensor*) -- the second strided matrix to be matrix
    multiplied

Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
