# Numpy 2 is not supported yet, because the server linien, (installed on the
# RedPitaya) must use the same Numpy version as the client (installed with
# Nix). The server linien is bound to use Numpy 1 because Numpy maintainers
# don't distribute pre-built wheels for the armv7l architecture of
# RedPitaya, and it is unfeasible to build it natively there - something
# that `pip install numpy` naively tries to do. Hence, we are bound to use
# on the server the preinstalled Numpy 1 sourced in the .deb package that
# comes with the RedPitaya OS. See also:
#
# - https://github.com/linien-org/linien/commit/ebbb2276b500a18826d11893bb43699b65692c5e
# - https://github.com/linien-org/linien/issues/377
#
# To evaluate this package with python3.withPackages, use:
#
# pythonEnv = pkgs.linien-gui.passthru.python.withPackages(ps: {
# ps.linien-common
# # Other packages...
# });
#
# NOTE that the above Python environment will use Numpy 1 throughout all
# packages wrapped there (see expression in linien-gui), and this may
# trigger rebuilds for dependencies that depend on Numpy too. Be ready to
# also add more `packageOverrides` to make sure these other dependencies do
# build with numpy_1.
#
# Last NOTE: If you need more packageOverrides besides those provided in
# the `linien-gui` expression, beware of:
#
# - https://github.com/NixOS/nixpkgs/issues/44426
