95% of the time if I'm making nix a dependency it's just to install the correct version of python and poetry, then I let poetry handle the other dependencies. So it's totally possible to just use nix a little. My coworkers haven't even noticed the flake.nix in our repo, they just install those things by hand.

But then there's that 5% case where you do have to forge a demonic pact with the nix gods, and it's handy to have your summoning circle all warmed up and ready to go.

I had problems installing python dependencies with compiled library dependencies this way, eg pandas. Does that generally work for you?

Pandas is one of those for which poetry alone doesn't do the job. So I have nix install pandas alongside poetry so that when poetry tries to install pandas, the non-python dependencies are all lined up.

Here's a (too verbose, sorry) example: https://stackoverflow.com/a/74944857/1054322

It works well on all of my linux boxes. On my mac it takes forever because it wants to rebuild the linux universe. Given that the system architecture is a parameter, I think there should be a way to rewrite my flake (or update the nixpkgs numpy) to just rely on bsd tools in those cases, but I haven't found it yet.

That's what's holding me up from recommending it to my team. I'm happy to just use linux everywhere, but they aren't.
