Build failure: python310Packages.numpy

[Namr]

Nixpkgs version

• Unstable (25.11)

Steps to reproduce

The following shell.nix can reproduce the issue, but any attempt to build python310Packages.numpy will cause the same failure.

{ pkgs ? import <nixpkgs> {} }:

let
  pythonPackages = pkgs.python310Packages;
in pkgs.mkShell rec {
  name = "test";
  venvDir = "./.venv";
  buildInputs = [
    pythonPackages.python
    pythonPackages.numpy
  ];
}

Can Hydra reproduce this build failure?

Hydra doesn’t try to build the package.

Additional context

This issue was caused by the upgrade to Numpy 2.3.0: 12eec2b which deprecates support for Python 3.10 (see: https://numpy.org/news/#numpy-230-released). I would submit a patch to change the pythonOlder call to indicate the deprecation of 3.10, but this would still cause build failures since many of the 3.10 packages require numpy.

I would submit a patch to change the pythonOlder call to indicate the deprecation of 3.10

That would be a good idea.
