Don't use void tags in autodiff
simonbyrne opened this issue · comments
Once JuliaDiff/ForwardDiff.jl#279 is fixed, it should be easier to use non-Void tags in the autodiff machinery. This will allow optimisation over functions which themselves use Dual numbers.
e.g. see SciML/OrdinaryDiffEq.jl#200
Permission granted to re-ping once it is merged and I'd love to take care of it.
