Hello, I am new to Julia and Optim.jl. I am trying to figure out how to make my constrained NLP problem work within this package. I am getting the following error:
`ERROR: LoadError: MethodError: no method matching Optim.BarrierLineSearchGrad(::Vector{Float64}, ::Matrix{Float64}, ::Optim.BarrierStateVars{Real}, ::Optim.BarrierStateVars{Real})
Closest candidates are:
Optim.BarrierLineSearchGrad(::Vector{T}, ::Matrix{T}, ::Optim.BarrierStateVars{T}, ::Optim.BarrierStateVars{T}) where T at C:\Users\dhs0020.julia\packages\Optim\Zq1jM\src\multivariate\solvers\constrained\ipnewton\interior.jl:153
sol = solve(problem, IPNewton(); maxiters = 1, show_trace = true, show_every = 1)
return sol
end
`
my constraints function is setting the constraints vector to a Vector{Real} element, so I am not sure why IPNewton method is thinking that the constraints vector type is Vector{Float64}, which is what is I believe the cause of this error is.
I am absolutely stuck and I would appreciate any help provided to get over this issue.
