poetry add scikit-learn does not work on m1 mac

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: 2021 MacBook Pro with Apple M1 Pro - macOS Monterey 12.3.1
• Poetry version: 1.1.13
• Link of a Gist with the contents of your pyproject.toml file:

[tool.poetry]
name = "example"
version = "0.1.0"
description = ""
authors = ["SamEdwardes <[e-mail]>"]

[tool.poetry.dependencies]
python = "^3.9"
requests = "^2.27.1"

[build-system]

Issue

I am unable to install scikit-learn using poetry on an m1 macbook pro. Everything seems to work:

$ poetry init --no-interaction --name example
$ poetry env use python3.10
$ poetry add requests
$ poetry run python
Python 3.10.4 (main, May 16 2022, 17:43:57) [Clang 13.1.6 (clang-1316.0.21.2.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Until I attempt scikit-learn:

$ poetry add -vvv scikit-learn 

expand for output

Failed to add packages, reverting the pyproject.toml file to its original content.

There is known issue with scikit-learn on the M1 mac (https://scikit-learn.org/stable/install.html#installing-on-apple-silicon-m1-hardware):

The recently introduced macos/arm64 platform (sometimes also known as macos/aarch64) requires the open source community to upgrade the build configuration and automation to properly support it.

At the time of writing (January 2021), the only way to get a working installation of scikit-learn on this hardware is to install scikit-learn and its dependencies from the conda-forge distribution, for instance using the miniforge installers:

https://github.com/conda-forge/miniforge

The following issue tracks progress on making it possible to install scikit-learn from PyPI with pip:

https://github.com/scikit-learn/scikit-learn/issues/19137

But it looks like this was fixed in a recent PR (https://github.com/scikit-learn/scikit-learn/pull/21827). I also confirmed that I was able to install scikit-learn via pip on my m1.

A few more details that may help:

• Using a python installed via pyenv (e.g. pyenv install 3.10.4)

Thank you @branchvincent. I did see your comment. I though I tried setting python = ">=3.9,<3.11" and it still did not work unless I installed scipy first. That was incorrect! I think I just got mixed up in all of the many variations I tried.

To close the loop and to confirm for future readers the following works:

$ poetry init --no-interaction --name example --python ">=3.9,<3.11"
$ poetry add scikit-learn

This command will guide you through creating your pyproject.toml config.


You can specify a package in the following forms:
  - A single name (requests)
  - A name and a constraint (requests@^2.23.0)
  - A git url (git+https://github.com/python-poetry/poetry.git)
  - A git url with a revision (git+https://github.com/python-poetry/poetry.git#develop)
  - A file path (../my-package/my-package.whl)
  - A directory (../my-package/)
  - A url (https://example.com/packages/my-package-0.1.0.tar.gz)

@SamEdwardes did you see my comment? https://github.com/python-poetry/poetry/issues/5628#issuecomment-1129422709

the issue here is python = "^3.9" is filtering out the latest scipy. Can you verify that the following works for you:

$ cd "$(mktemp -d)"
$ poetry init --no-interaction --name example --python '>=3.9,<3.11'
$ poetry add scikit-learn
