Install scikit-learn within a virtual Python environment on Mac (Apple Silicon M1)

install_python_libraries_apple_silicon_m1.md

Issue

I was trying to install scikit-learn with:

python3 -m pip install scikit-learn

but it failed with a ton of errors while dealing with numpy as a dependency. Main error:

clang: error: the clang compiler does not support 'faltivec', please use -maltivec and include altivec.h explicitly

Fix

https://scikit-learn.org/dev/install.html#installing-on-apple-silicon-m1-hardware suggests using miniforge.

Steps

1. Download the correct version of miniforge binary from https://github.com/conda-forge/miniforge. In my case:

wget `https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-MacOSX-arm64.sh

2. Run:

bash Miniforge3-MacOSX-arm64.sh

3. Reload your shell. You can simply open a new tab or a new terminal.
4. Create a new environment with conda

conda create --name py392

5. Activate the created environment

conda activate py392

6. Install the version of Python that you need within this environment

conda install -y python==3.9.2

7. Install scikit-learn

conda install -y scikit-learn
