[SciPy-User] Gradient of spline interpolation at a point wrt changing the knot points

I'm using scipy.interpolate.InterpolatedUnivariateSpline in a statistical
application.

y = InterpolatedUnivariateSpline(x0,y0)(x)

I need the derivatives of the spline evaluated at a given point with
respect to changing the knot values (y0).  That is, I need the derivative
of y wrt to y0. Is there a way I could compute this?

Thank you,
John
