Not solving the optimization model with the SCIP solver about scip.jl

[matbesancon]

Hello, did you install SCIP separately from the Julia package?
See the instructions here: https://github.com/scipopt/SCIP.jl#custom-installations

Dear Mathieu Besançon @matbesancon

Yes I have installed the latest version of SCIP separately.

[matbesancon]

Can you do "using SCIP" in a Julia session and see if it also kills the session?
I would invite you to check the other issues opened for Windows:
https://github.com/scipopt/SCIP.jl/issues?q=is%3Aissue+Windows+

Yes I easily do this command "using SCIP" and there are no errors. Only by defining the variables and solving the problem you will get the mentioned error.
Please see the figure below: The command "optimize!(model)" that I type faces the problem of solving.

Does anyone know where the problem is?

[matbesancon]

Can you try:

o = SCIP.Optimizer()

Dear @matbesancon

Which line should I replace this command with? My model is below:

using JuMP, SCIP
model = Model(SCIP.Optimizer)
set_attribute(model, "display/verblevel", 0)
set_attribute(model, "limits/gap", 0.05)
@variable((model), x);
@variable((model), y);
@objective((model), Min, (x) + (y));
@constraint((model), x >= 0)
@constraint((model), y >= 5)
optimize!(model)
println(value.(x))
println(value.(y))

[matbesancon]

Just using SCIP @show @eval SCIP libscip o = SCIP.Optimizer() As an alternative attempt, please run the code that you already have but without the line setting verblevel to 0. You can do both. Thanks!

It did not run again without settings.

[matbesancon]

The path of libscip is in .julia/artifacts, which means SCIP was not installed or recognized.
Please follow the similar steps as in this issue: #248

The problem was solved. Thanks.
