MethodError: anyeltypedual(::Type{Union{}}) when passing ODEProblem as a parameter

[EllissoideRotondo]

I am trying to implement a shooting method using a NonlinearProblem. An ODEProblem is passed as a parameter to the NonlinearProblem (to avoid recreating a new ODEProblem at each iteration), and during evaluation of the nonlinear function the properties of the ODEProblem (u0, tspan, p, etc.) are modified. However, when passing the ODEProblem as a parameter, I get the error MethodError: anyeltypedual(::Type{Union{}}) is ambiguous. Everything works correctly if the ODEProblem is created inside the nonlinear function, but being able to pass it as a parameter would be more convenient.

Minimal Reproducible Example

using OrdinaryDiffEq, NonlinearSolve, StaticArrays

# ODE problem
f(u, p, t) = SA[u[2], 1.5u[1]^2]
ode = ODEProblem(f, SA[0.0, 0.0], (0, 1))

## Example 1: ODE is not passed as a parameter, no errors
fun_no_ode(u, _) = begin
    ode = ODEProblem(f, SA[4.0; u], (0, 1))
    sol = solve(ode, Tsit5(); reltol = 1e-8, abstol = 1e-9)
    return sol[end][1] - 1
end
prob1 = NonlinearProblem(fun_no_ode, -2.0)
sol = solve(prob1, TrustRegion(), show_trace = Val(true))

## Example 2: ODE is passed as a parameter, error is thrown
fun_with_ode(u, ode) = begin
    ode = remake(ode, u0 = SA[4.0; u])
    sol = solve(ode, Tsit5(); reltol = 1e-8, abstol = 1e-9)
    return sol[end][1] - 1
end
prob2 = NonlinearProblem(objective, -2.0, ode)
sol = solve(prob2, TrustRegion())

Don't provide the ODE as a parameter 😓. Use a functor if you don't want to Box the ODE.

[ChrisRackauckas]

No we can just fix this. anyeltypedual on this just needs to lower to u0 and p

[EllissoideRotondo]

I don't know if this is useful to know, but I just realized I have some code I wrote 6 months ago where this behavior is used and the code runs without any errors, with the only difference being it uses the NLsolveJL solver instead of TrustRegion. I tried switching to NLsolveJL solver for the MWE above, but it still throws the same error with the current version.

With this environment and NLsolveJL solver, the MWE above runs successfully:

It's trivial to fix but I just haven't gotten around to it. But if you help me a little bit this could be done in a few hours. Try the following in your REPL:

function DiffEqBase.anyeltypedual(prob::ODEProblem,
    ::Type{Val{counter}} = Val{0}) where {counter} where {N, T <: NTuple{N, <:Number}}
    DiffEqBase.anyeltypedual(prob.u0, prob.p, prob.tspan)
end

and then run it.

I'm not a Julia expert at all, but I'm happy to help.
I had to slightly modify your code snippet to avoid errors.
If I pass the inputs as a Tuple, i.e. DiffEqBase.anyeltypedual((prob.u0, prob.p, prob.tspan)), then the code runs fine.
Thank you!

[ChrisRackauckas]

SciML/DiffEqBase.jl#1058 handles this and throws a much better error message.

As of NonlinearSolve v4 (scheduled to release next week) this problem is fixed
