I tried adding poetry to extraPackages but didn't work:

      devShell = prev.poetry2nix.mkPoetryEnv {
        projectDir = ./.;
        editablePackageSources = {
          monix = ./monix;
        };
        extraPackages = ps: with ps; [
          poetry
        ];
      }.env;

It failed:

error: collision between `/nix/store/2bn57zh92ajirim070nkzqyp7ialwf3g-python3.9-poetry-core-1.0.7/lib/python3.9/site-packages/poetry/__init__.py' and `/nix/store/jv411g1gg5njclqnas9md97y0p55z06c-python3.9-poetry-1.1.12/lib/python3.9/site-packages/poetry/__init__.py'

Hello! I'm trying to use poetry2nix for a kubeflow project we have. This means it unfortunately runs with Py3.6 (soon 3.8 I heard). I got to a point where I was able to specify Python 3.6, but now I am getting a version mismatch arrow:
error: arrow-cpp version (7.0) mismatches pyarrow version (2.0)

I'm not entirely sure where it gets arrow-cpp 7.0 from, my pyarrow version specified in the poetry.lock is 2.0.

My default.nix:

{ pkgs ? import <nixpkgs> {} }:
let
python36 = import <darwin20.python36> { system = "x86_64-darwin"; };
myAppEnv = pkgs.poetry2nix.mkPoetryEnv {
projectDir = ./.;
editablePackageSources = {
ml-policy-compliance = ./ml_policy_compliance;
};
};
in myAppEnv.env

hello people. I'm trying to get a proper devShell. So far I have followed the example from https://github.com/nix-community/poetry2nix#example-shellnix

Hi, Jairo. This is how i define devShell in most cases

        devShell = (pkgs.poetry2nix.mkPoetryEnv {
          projectDir = ./.;
          editablePackageSources = {
            exyaru = ./.;
          };
        }).env.overrideAttrs (oldAttrs: {
          buildInputs = [ pkgs.poetry ];
        });

Anyone here got a tip for me how to overcome this build error? https://paste.sr.ht/~x10an14/9ad4459b175e516d04bc3fb17123c3206da6a3c0#nix%20build%20log%20error-L94 It's my first time using poetry2nix, so I may have messed up my flake.nix...

Try to define mkPoetryApplication with override like this

    defaultPythonSetup = {
      projectDir = ./.;
      overrides = prev.poetry2nix.defaultPoetryOverrides.extend ( self: super: {
              prospector = super.uengine.overridePythonAttrs (
                old: {
                  buildInputs = (old.buildInputs or [ ]) ++ [ self.poetry ];
                }
              );
            });
          };

Sorry for formatting

here how i define such override (whole example)

      overlay = nixpkgs.lib.composeManyExtensions [ poetry2nix.overlay
        (final: prev: {
          # The application
          myapp = prev.poetry2nix.mkPoetryApplication {
            projectDir = ./.;
            python = prev.python38;
            overrides = prev.poetry2nix.defaultPoetryOverrides.extend ( self: super: {
              brokenPackage = super.brokenPackage.overridePythonAttrs (
                old: {
                  buildInputs = (old.buildInputs or [ ]) ++ [ self.poetry ];
                }
              );
            });
          };
        })
      ];

This is overlay for nixpkgs as it appears in poetry2nix README example

i should be more accurate next time. hope my guess is lucky )

Does this git diff look correct to you? I get the same error as previously with it =/ I must admit I'm not really understanding what I'm doing^^
