Insert the missing method to find the univariate spline interpolation:
from scipy.interpolate import @(16)
import numpy as np
xs = np.arange(10)
ys = xs**2 + np.sin(xs) + 1
interp_func = @(16)(xs, ys)
from scipy.interpolate import UnivariateSpline
import numpy as np
xs = np.arange(10)
ys = xs**2 + np.sin(xs) + 1
interp_func = UnivariateSpline(xs, ys)
