Hi!
I did, actually. But then the project stopped for other reasons, so I haven’t looked at it in a while. Going back to it now, I see that I have a program that works (i.e. it runs, and passes all numerical gradient tests), but is rather ugly. Stripping it down to something I’m comfortable with posting publicly would take a bit of work, but if you like I could send it to you privately? Then maybe you can make a minimal working example to post here
