scipy.special.jv not found?

[nbecker]

It would take some work to produce a minimal example, but maybe this will suffice?

import numpy as np
from scipy import constants
from numba import jit
import numba_scipy
import scipy.special as sp
...
@jit(nopython=True)
def circular_patch(a, h, L_op, er, theta, phi):
    # effective radius
    ae = a * np.sqrt(1 + (2 * h / (np.pi * a * er)) * (np.log(0.5 * np.pi * a / h) + 1.7726))
    k0 = 2 * np.pi / L_op
    sin_theta = np.sin(theta)
    bfn0 = sp.jv(0, k0 * ae * sin_theta)
    bfn2 = sp.jv(2, k0 * ae * sin_theta)
    Jp_02 = bfn0 - bfn2
    J_02 = bfn0 + bfn2

    # ((k0 * ae * exp(-1i*k0*r))/(2*r)) is a constant wrt theta & phi , so is
    # not included below.
    E_theta = np.abs(-1j * (np.cos(phi) * Jp_02))
    E_phi = np.abs(1j * (np.cos(theta) * np.sin(phi) * J_02))
    magEF = np.sqrt(E_theta * E_theta + E_phi * E_phi)

    return magEF

Did I use numba_scipy incorrectly?
I installed from git as:
pip install git+https://github.com/numba/numba-scipy.git
(normal pip install failed on python3.11 as others have reported before)

I have tried both sp.jv (0,...) and sp.jn (0,...) and both gave similar error.
