Cannot load HiGHS through JuMP

[mkyl]

I'm unable to access HiGHS in JuMP. I'm running Julia 1.7.0 on macOS 12.2.1. Minimal example:

What is import Pkg; Pkg.status()?

[odow]

And versioninfo()

[odow]

The fact you've had these two failures, jump-dev/Clp.jl#131, makes me suspicious of your Julia installation.

• How did you install Julia?
• What machine is this?

What happens if you go:

julia> using HiGHS_jll

julia> HiGHS_jll.is_available()

[odow]

Any update on this?

[dvaish]

I am having a similar issue. I installed HiGHS and it was working on my model earlier, but then stopped working seemingly spontaneously. When I run HiGHS_jll.is_available() I get false. I am using an M1 Mac and I have looked around a bit to find that BinaryProvider seems to be causing issues on M1. BinaryProvider is failing to compile. I am unsure of why the model was working before, though.

[odow]

HiGHS does not use BinaryProvider. What is import Pkg; Pkg.status()? and versioninfo()?

[dvaish]

[87dc4568] HiGHS v0.2.3

You have an old version of HiGHS installed that does not support M1. The current version of HiGHS.jl is v1.1.1.

You need to update your packages. You need JuMP 0.22 or 0.23, HiGHS v1.1, and Ipopt v1

If import Pkg; Pkg.update() doesn't work, then run import Pkg; Pkg.pkg"add HiGHS@1" to see which package is preventing you from updating.

Julia installed via homebrew for M1 Mac in \opt\homebrew

Download an official binary from https://julialang.org/downloads/

[dvaish]

Resolved, thank you! For some reason it was downloading old versions of the package. Did not have to change the Julia binary.

[odow]

If you can confirm that the latest version of HiGHS works on the M1, I'll close this issue. It's likely that @mkyl had the same problem of installing an old version.

Similarly to jump-dev/Clp.jl#131 (comment), I'll note that the M1 is not officially supported by Julia, so you can expect to encounter issues like this.

[dvaish]

On my model, HiGHS does seem to work on the M1. I think there was just an issue where is was consistently downloading the old version (even after removing the package and redownloading it).

[odow]

You probably have a conflict with other packages. In general, you should use a new environment for each project to avoid these compatibility issues.

[odow]

Closing because HiGHS does work on the M1. It's likely that @mkyl had an out-dated version.

@mkyl, if you still have trouble after updating your packages to the latest version, please re-open this issue, or post on the community forum: https://discourse.julialang.org/c/domain/opt/13
