JuMP not updating to latest version

Specific Domains Optimization (Mathematical)
1

When I call pkg> update JuMP, I only get version v0.19.2, while the latest stable release listed at Juliaopt.org is v0.21. I’d like to use some features that started in v0.20.

The problem is probably that you have some older version of other package (like a solver) that depends on 0.19 and therefore disallows the update.

I think the easiest way to debug is to do:

pkg> add JuMP@0.21

And see the error that will probably arise. The error will tell which packages conflict which this version of JuMP.

Thanks, that does seem to be what’s going on. I’ve updated the Gurobi package and still get the error that it’s incompatible. However, Gurobi is on the list of solvers in the installation guide for JuMP v0.21.

(v1.1) pkg> add JuMP@0.21

If you read the output carefully, you will see that:

  • You seem to have restricted Gurobi to version 0.6.0 that is NOT the last version of Gurobi.jl package (0.7.6).
  • The problem is that LinQuadOptInterface is restricting the versions of MathOptInterface, LinQuadOptInterface seems to have been inherited from an older state of your environment, it is not needed for the last versions of JuMP and Gurobi, do you need it?

I didn’t specifically install LinQuadOptInterface - presumably it came with Gurobi or another solver package. I’m not trying to restrict any packages to certain versions and don’t understand what I should be doing to resolve this.

Delete LinQuadOptInterface and try again:

Pkg> rm LinQuadOptInterface
Pkg> add JuMP@0.21

If it yet do not work, the dirty but fast way (i.e., should not be necessary, but if you are a begginer it is easier than trying to read the output, that I admit, is a little bit arcane) for solving it is removing all packages in your environment and installing just what you need, i.e.:

Pkg> st # look at everything you have installed
Pkg> rm ... # names of everything you have installed
Pkg> add JuMP@0.21 Gurobi # and any other packages you are sure you need

I think there must be more to it. LinQuadOptInterface is definitely used by Gurobi and other solvers I use (see here), but it’s not something I can see the status of or remove.

pkg> remove LinQuadOptInterface

If you see here, LinQuadOptInterface is not directly used by the last version of Gurobi.jl, more than that, I have an environment with JuMP and Gurobi installed and:

(@v1.4) pkg> activate .
(examples) pkg> st -m
[...]
  [2e9cd046] Gurobi v0.7.6
[...]
  [4076af6c] JuMP v0.21.2

  [8f399da3] Libdl 
  [37e2e46d] LinearAlgebra 
  [56ddb016] Logging 
  [d6f4376e] Markdown

Note that the list is complete (option -m is being used) and it is ordered by alphabetical order, so I have no package LinQuadOptInterface installed.

Did you try to remove everything (except LinQuadOptInterface as it seems to not exist) and reinstall just what you need? More than that, try to add Gurobi@0.7.6 to your project to check if it is allowed. You can also execute gc before (garbage collector of the Pkg) to remove unused packages, with any luck it will be able to remove LinQuadOptInterface that seems to be on limbo.

If everything else fails, you can always start again from a fresh ~/.julia, make a backup of your old environment (mv ~/.julia ~/.julia_old), delete your project Manifest file (rm Manifest.toml), and instantiate the project again:

julia> import Pkg
julia> Pkg.activate(".")
julia> Pkg.instantiate()

But it is also nice to check if your Project.toml has no [compat] section forcing the use of specific versions, nor it does mention LinQuadOptInterface.

What worked for me in the end was removing Gurobi, updating JuMP (which then did update to v21), and then re-adding Gurobi (which installed as v.0.7.6).

hi, i’d like to use Gurobiv0.6.0 but i got something wrong

can you tell me which version of Gurobi you install ? i think i should install another version of it ,thanks!!

I guess this is to do with your attempts to run Pajarito: run convex with pajarito？(try to solve misdp with complex variable) · Issue #438 · jump-dev/Convex.jl · GitHub

You should be able to use ] add Gurobi@0.8 instead. However, you will need an old copy of Gurobi (the solver). One of these should work: Gurobi 8.0, 8.1, or 9.0 (not 9.1).

Here are the installation instructions: GitHub - jump-dev/Gurobi.jl at v0.8.1

If you’re still struggling after this, please open a new post, rather than continuing this thread.
