I downloaded Julia 1.3.1.

```nohighlight
versioninfo()

Julia Version 1.3.1
Commit 2d5741174c (2019-12-30 21:36 UTC)
Platform Info:
  OS: macOS (x86_64-apple-darwin18.6.0)
  CPU: Intel(R) Core(TM) i7-7920HQ CPU @ 3.10GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-6.0.1 (ORCJIT, skylake)
Environment:
  JULIA_EDITOR = atom -a
  JULIA_NUM_THREADS = 4

```

Most things seem to work well except when I train models in MLJ:

```nohighlight
using MLJ

X, y = @load_boston;
train, test = partition(eachindex(y), .7, rng=333);

@load ARDRegressor
mdl = ARDRegressor()
mach = machine(mdl, X, y)
fit!(mach, rows=train) 

```

fit!() gives the following in REPL:  
`Intel MKL ERROR: Parameter 15 was incorrect on entry to DSYEVR.`

Here is the detailed message:

```nohighlight

Here are the regression models that did not work:

Have you tried Julia 1.2? I’ve just noticed that MLJModels does not have testing for Julia 1.3, but the tests for MacOS/julia 1.2 are passing. The version of scikit-learn getting installed in that case is shown below

```julia

Do you know what version is being installed in your case?

Yes, it works in Julia v1.2.  
I trained all 49 regression models matching the Boston housing data.  
Interestingly: first time compilation was faster in Julia v1.2 than v1.3…

I can confirm that MLJModels also fails CI tests on julia 1.3, 1.4 for MacOS only:

> [@Julia 1.3, 1.4 on MacOS and Intel MKL Error](https://discourse.julialang.org/t/julia-1-3-1-4-on-macos-and-intel-mkl-error/36469):

> Sorry in advance if this is the wrong place to post. I am looking for any help narrowing down the source of a MacOS only / Julia 1.3, 1.4 only failure for the [MLJModels.jl](https://github.com/alan-turing-institute/MLJModels.jl) package: “Intel MKL Error”. Copied from the [issue raised there](https://github.com/alan-turing-institute/MLJModels.jl/issues/212): I have introduce CI on [this branch](https://github.com/alan-turing-institute/MLJModels.jl/tree/extend-ci) for julia 1.3 and julia 1.4, where testing in [now failing](https://travis-ci.com/github/alan-turing-institute/MLJModels.jl/jobs/302128369#L544) for MacOS. The error is triggered by testing of the wrapped scikit-learn (python) clustering models. According to the travis logs, the conda installations for scikit…
