There are some different/new tools for creating your own Python packages these days. It's still not truly solved in the sense of having a single clear winner , but one of these new package generation tools might serve you better: poetry2nix: https://github.com/nix-community/poetry2nix mach-nix: https://github.com/DavHau/mach-nix dream2nix: https://nix-community.github.io/dream2nix/guides/getting-sta... pynixify: https://github.com/cript0nauta/pynixify pip2nix: https://github.com/nix-community/pip2nix The tools available to you at the time (pypi2nix and maybe python2nix, if it was a long time ago) have been abandoned in favor of the newer tools, I think chiefly poetry2nix but I'm not sure. There's still the Nixpkgs buildPythonPackage stuff, I think, if your goal is to upstream a lib into Nixpkgs. But if you just want to build your own Pyth
Read the rest
on applications and vendorize the deps (e.g., for work), you might try one of the tools above, which weren't available 3+ years ago. dream2nix is by the author of mach-nix IIRC and has the goal of establishing a unified standard and codebase for ${proglang}2nix type package generators. But mach-nix is still maintained and might be the more feature-complete choice between them. Maybe Nix-y Python users and developers can reply with some of their experiences using those tools for real projects :)
In Nix: Taming Unix with Functional Programming
siraben·Nov 24, 2020
Note: these points concern Nix, the situation may be different on Guix > * Do packages need to be 'ported' to Nix or its build / install system? If so, how much effort will it take and on what factors the effort required to port may vary substantially? (eg: Programming Language). Yes. To make Nix really work it has to be pervasive and this sometimes means porting packages again, however there's a lot of automation around this, see[0] for ones that leverage existing build systems in other languages. Autoconf and cmake packages are already accounted for by the default builder, and usually only the dependencies have to be specified. > * How is disk space usage? Is there any kind of deduplication? The Nix store can be intensive on memory, as once a dependency such as glibc is updated, all the reverse dependencies (i.e. the set X such that X

depends on glibc directly or transitively) have to be rebuilt as well. There is an option to optimise the store, but I don't know how much it helps in practice, see[1]. Garbage collection can be invoked manually or automatically to free up unused store entries. > * Other performance characteristics - bandwidth (delta upgrades possible?), startup time (I hope this will be good).. By startup time you might be referring to NixOS. It's very good on my Late 2013 13-inch MacBook Pro, around 20 seconds to go from cold boot to login screen.
