tl; dr: should've looked upstream first regarding the dm-tree package

The original question remains in the thread but is mostly confused.

Thank you! ... that seems like one of the variants I tried, but maybe I didn't get it quite right or there's a more subtle issue with this particular package ... I'll try again

I put a bit more of the intended usage context in the thread above, but have now summarized what was useful and pushed the original question which was largely confused below its break.

But, of course, this doesn't really begin to get to the root of the issue, for which I definitely should've looked upstream first

I've tried a couple different overrides, but none of them seem to take:

pytorch-lightning = pkgs.python311Packages.pytorch-lightning;

pytorch-lightning = super.pytorch-lightning.override { preferWheel = false; };

pytorch-lightning = super.pytorch-lightning.overridePythonAttrs (old: {
  unpackPhase = ''
    set -eux
    echo "THIS SHOULD NOT BUILD!"
    exit 1
  '';
});

I've tried specifying the dependency as both of these ways:

pytorch-lightning = "2.1.3"

pytorch-lightning = { url = "https://files.pythonhosted.org/packages/f6/95/a662bd12b255ee3b59c975277c67398410b5810ee72ff11e34134e10cc9a/pytorch_lightning-2.1.3-py3-none-any.whl" }

Even when directly pointing it directly at the wheel file, it still gives the same error
