Hi,

I have the same problem, and I haven’t found a way to solve it. I answered your question on the new topic you created:

> Hi, Based on what was said in a recent topic, I would recommend the approach taken by [TaylorDiff.jl](https://github.com/JuliaDiff/TaylorDiff.jl) for higher order automatic differentiation. See the discussion and links in that topic: [https://discourse.julialang.org/t/is-it-possible-to-do-nested-ad-elegantly-in-julia-pinns/98888](https://discourse.julialang.org/t/is-it-possible-to-do-nested-ad-elegantly-in-julia-pinns/98888)
