INTEL MKL ERROR on MacOS

[OkonSamuel]

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?

[OkonSamuel]

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=conda as default python distribution on MacOS(This doesn't error in Linux build)

[OkonSamuel]

Although adding the following code to my tests prevents those errors am still puzzled why it doesn't error in Linux builds.

Conda.add("nomkl")
Conda.add("scikit-learn")
Conda.rm("mkl")

add this in your .travis.yml

env:
  - PYTHON=Conda LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.julia/conda/3/lib

the problem is the env variable is not properly set to the right location in MacOS

[ppalmes]

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:

export PYTHON=Conda
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.julia/conda/3/lib

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]

you have to do Pkg.build() so that Conda and PyCall will use these new information.

[ppalmes]

export PYTHON=Conda export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.julia/conda/3/lib

in julia prompt:
using Pkg; Pkg.build()

Same Error :(

[mertsaner]

It happens when I use Pyplot otherwise it is okay, I use BigSur 11.2.3 on M1 Macbook

[ppalmes]

check on that directory if you have the mkl lib. find it and put it there.

[ppalmes]

you can also remove mkl by using nomkl

Conda.add("nomkl")
Conda.rm("mkl")
pyimport_conda("mkl", "mkl")

Same Error :(

make sure you export those commands in the same terminal and run julia and build the packages.

I tried but, it did not work correctly, something is wrong with Julia but I do not what is
