INTEL MKL ERROR on MacOS #182
Description
Hi.
I get the following error in travis tests when using Conda on MacOS
INTEL MKL ERROR: dlopen(/Users/travis/.julia/conda/3/lib/libmkl_intel_thread.dylib, 9): Library not loaded: @rpath/libiomp5.dylib
Referenced from: /Users/travis/.julia/conda/3/lib/libmkl_intel_thread.dylib
Reason: image not found.
Intel MKL FATAL ERROR: Cannot load libmkl_intel_thread.dylib.
I don't get these error on Linux or when i use my local python distribution (That's why am opening an issue here). No error shows if i remove mkl with Conda.rm("mkl")
Any help would be appreciated. Thanks

Can you give a self-contained example that illustrates the error? What is the test that is failing?

Thanks @stevengj
Sorry for my choice of words. I should have said errored tests. https://travis-ci.com/github/alan-turing-institute/MLJModels.jl/jobs/339809727#L470. This is as a result of using
PYTHON=condaas default python distribution on MacOS(This doesn't error in Linux build)OkonSamuel commentedon May 26, 2020
Although adding the following code to my tests prevents those errors am still puzzled why it doesn't error in Linux builds.

add this in your .travis.yml
the problem is the env variable is not properly set to the right location in MacOS
ppalmes commentedon Nov 18, 2020
can we have a fix on this in MacOS? for those with conda/python working, this is issue won't bite them. from fresh .julia or new install of conda/pycall, without properly exporting:
in their startup shell, installing conda/python will fail.

Hi there,
I have the same problem in my Macbook but I did not understand what to do exactly. What is our .traves.yml? My username is mertsaner. So, what is .mertsaner.yml? Could you describe in a detailed way what we need to do solve the problem? Thanks,

I have tried to write these two to the my shell but it did not worked out
ppalmes commentedon Apr 4, 2021
you have to do Pkg.build() so that Conda and PyCall will use these new information.

export PYTHON=Conda export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.julia/conda/3/libin julia prompt:
using Pkg; Pkg.build()mertsaner commentedon Apr 4, 2021
Same Error :(
mertsaner commentedon Apr 4, 2021
It happens when I use Pyplot otherwise it is okay, I use BigSur 11.2.3 on M1 Macbook

check on that directory if you have the mkl lib. find it and put it there.
ppalmes commentedon Apr 4, 2021
you can also remove mkl by using nomkl
ppalmes commentedon Apr 4, 2021
make sure you export those commands in the same terminal and run julia and build the packages.
mertsaner commentedon Apr 11, 2021
I tried but, it did not work correctly, something is wrong with Julia but I do not what is
mertsaner commentedon Apr 11, 2021
Pluto is okay, since even I do not use Pluto, it gives same error within Julia every time, I try to plot something or write Pyplot()
mertsaner commentedon Apr 11, 2021
like using Pkg, Add PyPlot()
ppalmes commentedon Apr 11, 2021
did you follow the steps about exporting PYTHON and LD_LIBRARY paths? did you check if MKL lib can be found in the location that the error indicated? please provide more details and more info. if you don’t provide details, we cannot guess too what is the problem.
ppalmes commentedon Apr 11, 2021
what is your julia version. try running these commands in julia shell to avoid any issues from other packages.
ppalmes commentedon Apr 11, 2021
did you try the Conda commands suggested above?
deszoeke commentedon Jul 22, 2021
I had to do some tugging to get GR to compile, after which I got this PyPlot error. The Conda commands worked.
