Support to MacOS

[Nikeshbajaj]

Hi, I have been using glmnet_python on linux, but couldn't run in on MacOS, even though the conda-forge channel indicates the support of OSX-64 (https://anaconda.org/conda-forge/glmnet_py).

I tried both, installing using conda forge, pip and even tried with compiling from source, yet I keep getting same error.

OSError: glmnet_python/GLMnet.so' (not a mach-o file)

Is there anyway to fix that or only linux is the option?

I managed to get glmnet_python running on my apple M3 Pro by installing gfortran with x86_64 architecture specific homebrew by following this guide: https://sixty-north.com/blog/pyenv-apple-silicon.html

Namely these are the steps that solved it for me:

1. make the command brew86 available according to above blog
2. brew uninstall gfortran - to uninstall arm gfortran (to make sure the x86_64 version is used for building the .so binary)
3. brew86 install gfortran (install x86_64 gfortran)
4. delete the committed GLMnet.so file
5. pip uninstall glmnet_python (uninstall previously installed package)
6. pip install . ... this got me a functional glmnet_python and GLMnet.so on my apple M3 Pro
