Type FPFunctionalCache has no field caches error

Hi,
I am using BlackBoxOptim and I get this error when I run it.

Starting optimization with optimizer DiffEvoOpt{FitPopulation{Float64},RadiusLimitedSelector,BlackBoxOptim.AdaptiveDiffEvoRandBin{3},RandomBound{ContinuousRectSearchSpace}}

type FPFunctionalCache has no field caches

Does anyone have any idea what I’m doing wrong? I would really appreciate it.

Please read PSA: make it easier to help you and post a minimal example that demonstrates the error. Thanks!

You are right, sorry.

function Model()
...
end
prob = DDEProblem()
alg = MethodOfSteps(AutoTsit5(Rosenbrock23()))
obj = build_loss_objective(prob, alg,...)
bboptimize(obj)

Here I changed the alg from AutoTsit5(Rosenbrock23()) to Vern6() and it worked.

I tried run your code but I only got as far as

julia> function Model()
       ...
       end
ERROR: syntax: invalid identifier name "..."

@kristoffer.carlsson My problem was solved, I wrote just the structure of it here, I know it wouldn’t run.
When I changed the alg as I said above, I didn’t get the error anymore.
Thank you,

We should be able to run a minimum working example by copy-and-pasting it into the REPL.

We’re looking for something like

using Optim
function foo(x)
    return sum(x.^2)
end
optimize!(foo, [1.0])

instead of

using Optim
function foo(x)
    ... my model goes here ...
end
optimize!(foo, [1.0])
