Whenever I try to compile the solver declaration the following error appears
using JuMP, JuMPeR, Cbc, MathOptInterface
ModelD = Model(with_optimizer(Cbc.Optimizer))
Error message: UndefVarError: with_optimizer not defined
I also tried it that way and it didn’t work
ModelD = Model(solver=CbcSolver())
What is your JuMP version? The docs for the latest version do not mention
with_optimizer anymore (https://jump.dev/JuMP.jl/stable/quickstart/). Perhaps
julia> model = Model(Cbc.Optimizer);
JuMPeR uses an older version of JuMP (0.18), but it looks like you have a more recent version installed (probably >0.18).
If that’s the case, try pinning JuMP v0.18 and using the corresponding JuMP syntax.
I’m using this version v0.18.6
Unfortunately your suggestion didn’t work.
I’m using this version v0.6.0 of JuMPeR and v0.18.6 of JuMP
Please read the warning at the top of the documentation: https://jump.dev/JuMP.jl/stable/
Thanks for the suggestion, but I’m still unable to use the Cbc solver
