find_zero Roots.jl support

[themrzmaster]

Hi,
I've had a problem while testing Bijectors.jl that seems to be related with the fact that Zygote does not support the find_zero function.
Full Thread

Is there any plans to support it? Tracker AD supports it.
If someone could give me a hint if it makes sense or how I could help adding this compatibility, let me know.

Thanks

Can you write a minimial example of how this function is used, and a gradient which works with Tracker but not Zygote? There appears to be no explicit code for this in Tracker.

[mcabbott]

To be clear, I was hoping for a one-liner! I've no idea what this function does, what is its simplest input? And if you put that in gradient, does that reproduce the problem? Or does it work fine in all simple cases and only fail in the giant one with 5 other packages?

[themrzmaster]

yes, I will do it!

Sounds like you want an adjoint for some of the functions called by find_zeros

BTW like the SciML ecosystem Bijectors will probably switch to NonlinearSolve: TuringLang/Bijectors.jl#155
