I want to use spsolve in Numba, but it will report error.

Maybe the numba-scipy is helpful, but I do not how to use the numba-scipy in my code, coulde anyone help me, thanks.

here is an example code

```
from numba import jit
from scipy.sparse.linalg import spsolve
@jit(nopython=True)
def func1(~, ~,...):
A = dok_matrix(matrix_size, dtype=float)
b = np.zeros((matrix_size[0], 1))
x = spsolve(A, b) # this will be a error
return x
```
