Problem using NLopt in JuMP model

Specific Domains Optimization (Mathematical)
,
1

Hi,

I am trying to create a JuMP model using NLopt solver in Julia 1.5.3

using JuMP
using NLopt
model = Model(NLopt.Optimizer)

but I get the following error

ERROR: UndefVarError: Optimizer not defined
Stacktrace:
[1] getproperty(::Module, ::Symbol) at .\Base.jl:26
[2] top-level scope at none:1

Any hints?

Which JuMP version do you use?

Hi Mike, I am using JuMP v0.21.3 and NLopt v0.6.0

Hmm, the syntax is correct according to the tutorial of NLopt. Did you test the packages with the package manager? e.g., (@1.5) pkg> test NLopt

5

I think you need NLopt v0.6.1 for JuMP compatibility.
Have you tried updating your packages?

I updated NLopt using Pkg.update("NLopt") but I still get the version NLopt v0.6.0
How can I update to 0.6.1 ?

7

Yes, I did both Pkg.test("NLopt") and Pkg.test("JuMP") and everything looks fine but it is not working

In the package manager, try explicitly adding version v0.6.1:

(v1.5) pkg> add NLopt@0.6.1

This might fail with error messages, giving you a clue as to which package(s) are holding back NLopt.

@greg_plowman thanks for the hint. I run pkg> add NLopt@0.6.1 and I got the following errors

(@JuliaPro_v1.5.3-1) pkg> add NLopt@0.6.1

I am not sure what I should do exactly. I tried to add or update several packages that are mentionned but the issue has not been resolved.

What happens if you remove VegaLite?

Pkg.rm("VegaLite")
Pkg.update()

@greg_plowman Ι removed both Vegalite and Queryverse and I then updated the packages using Pkg.update(). It seems that Queryverse was blocking several Pkg updates including NLopt which now could be updated to version 0.6.1 . Then eventually I was able to create a JuMP model with NLopt optimizer. Thanks a lot !!
