maybe you could provide your expression? it will be much easier if there will be ability to experiment and run localy

{ description = “graphtage”;

inputs.nixpkgs.url = “github:NixOS/nixpkgs/d9e21f284317f85b3476c0043f4efea87a226c3a”;

outputs = { self, nixpkgs }: let pkgs = nixpkgs.legacyPackages.x86_64-linux; myPoetryEnv = pkgs.poetry2nix.mkPoetryEnv { pyproject = ./pyproject.toml; poetrylock = ./poetry.lock; }; in { devShell.x86_64-linux = myPoetryEnv; }; }

This is the full content of the flake

To reproduce, nix develop; graphtage --help

or just pyproject.toml

i take standard template for poetry2nix and tried to build. ended up with cythonization fail ((

Good Morning everyone. I am currently working on a little showcase workbench/projects for python based friends that don't know nix. They work fairly extensively with numpy and pandas so i tried adding those to poetry and so also to my environment. but it seems that that causes pandas and numpy to fully recompile them locally. i also tried pinning the versions to ones specifically available on nix. does anyone have some insight into this?

In reply to @graf_blutwurst:matrix.org
hm it seems i have to better understand build closures better. i assumed a dependency like that would be "low" enough that it could be picked up from the store/nixpkgs. thanks though! how do people deal with the long resulting build times? push the result from mkPoetryEnv to a binary cache?
