Problem with MKL_jll in Mac OS

General Usage

Hi there!

I am using the book pro-M2,
and now using VSC to implement Julia codes,

I just wrote several using the package and ran the program as below:

using LinearAlgebra
using JuMP
using Mosek
using MosekTools
using ControlSystems

But there is this warning (while I have not added any code yet!) I also restart Julia but still same warning:

┌ Warning: MKL_jll is not available/installed.
└ @ MKL ~/.julia/packages/MKL/kCNzy/src/MKL.jl:39

I searched and it seems MKL is not available for Mac, what should I do?

update: version of my MKL: 0.6.3, and it seems this warning is come with ControlSystem Package
Best

Hi @Sharara as I often say on here “Good enough for Jazz”. In this case think of learning to play jazz on the piano. You have to do a lot of exercises and scales before your masterclass performance.
I ask the audience - can we suggest some exercises @Sharara can run?

ps. What does using Pkg; Pkg.status() return?

Dear johnh

Thanks for your valuable advice and reply,
It is 2 up to 2 months since I moved to Julia (from MATLAB),
I started with Julia’s Youtube and followed all possible and related videos,
Then I tried to implement package examples one by one,

Then I started to implement my code, But

some errors or warnings are unknown to me and via search, I could not find reasonable answers,
for example, this topic, the previous week, for the same program, there was not such a warning,
But today it is coming and I could not solve it, I also tried to restart Julia and my system.

here is the output for status:

julia> using Pkg

@Sharara it looks like you are doing exactly what I did when new to Julia - installing lots of packages in global scope. I find that the packages then ‘trip over’ each other.

I would advise that you create separate projects for each model you want to work with or each new piece of work you want to work on
https://pkgdocs.julialang.org/v1/environments/

Can anyone reccomend a good writeup on Julia project workflows?

Also please remove UpdateJulia and I would remove the MKL package also

Hi

I could create a special project and as you mentioned it seems much better, thank you!

one challenge that I faced while I was using Julia, was understanding the Errors…

I could not understand it well…

Now I have implemented my LMI optimization algorithm, but I received this error:

MethodError: no method matching iterate(::Model)

Closest candidates are:
  iterate(!Matched::LibGit2.GitBranchIter)
   @ LibGit2 ~/.julia/juliaup/julia-1.10.2+0.aarch64.apple.darwin14/share/julia/stdlib/v1.10/LibGit2/src/reference.jl:343
  iterate(!Matched::LibGit2.GitBranchIter, !Matched::Any)
   @ LibGit2 ~/.julia/juliaup/julia-1.10.2+0.aarch64.apple.darwin14/share/julia/stdlib/v1.10/LibGit2/src/reference.jl:343
  iterate(!Matched::Pkg.Types.Manifest, !Matched::Int64)
   @ Pkg ~/.julia/juliaup/julia-1.10.2+0.aarch64.apple.darwin14/share/julia/stdlib/v1.10/Pkg/src/Types.jl:314
  ...


Stacktrace:
 [1] top-level scope
   @ /Volumes/University/Codes/Julia/SOF.ipynb:56

any help will save me …
