[Solved] Problem installing the Gurobi package on a cluster

Specific Domains Optimization (Mathematical)
1

Hello.

I’m doing a postgraduate degree and I have access to a cluster that has julia/1.7.3, gurobi/10.0.0 and gurobi/11.0.1.

Until now it was running gurobi/10.0.0 perfectly. However, in order to use the most recent version available (11.0.1), I removed the gurobi package (pkg> rm Gurobi) and I am trying to reinstall it to update to version 11. However, when running pkg> add Gurobi
I receive:

pkg> add Gurobi

Therefore, my suspicion may be that the version available on the cluster is 11.0.1, but I’m not sure if that’s it.

So, could anyone give a suggestion on how to resolve this?

I think I found a way around it. Browsing through old posts here on the forum I found this: . Here https://discourse.julialang.org/t/gurobi-v10-and-julia/90220/2 it suggests updating to a specific version of the Gurobi package with the command using Pkg; pkg"add Gurobi@0.11.4" therefore, considering my previous suspicion of possible incompatibility of version 11.0.2 in the file while in the cluster I have version 11.0.1 available, I There was an attempt to install a previous version of Gurobi. This way, accessing Releases · jump-dev/Gurobi.jl · GitHub I verified that the version prior to latest is version v1.2.3.

Therefore, when executing add Gurobi@1.2.3 the Gurobi package was installed. And when running,

using JuMP, Gurobi
v = MOI.get(Gurobi.Optimizer(), MOI.SolverVersion())

Finally I get:

Set parameter TokenServer to value "XXX.XXX.XXX.XXX"
"11.0.1".

In other words, I can finally use the desired version 11.0.1.

*If you can provide more details as to why I was unable to install the latest Julia Gurobi package, I would be grateful.

The issue is likely that your cluster is blocking us automatically installing the Gurobi binary.

Follow the Manual installation section of GitHub - jump-dev/Gurobi.jl: A Julia interface to the Gurobi Optimizer with Gurobi@1.3.

Thanks for the feedback! I will test your suggestion as soon as possible.
