I figured it out. The name is ofd_expressions, but the override must be named ofd-expressions Those were 8 hours well spent... :/

We try to normalize it across the ecosystem

Hello, I'm trying to use P2N to get a development environment for Langchain https://github.com/langchain-ai/langchain.

I have a simple env:

myenv = { poetry2nix, lib }: poetry2nix.mkPoetryEnv {
          projectDir = self;
          preferWheels = true;
}

and I get this error:

Hello, I'm trying to use P2N to get a development environment for Langchain https://github.com/langchain-ai/langchain.

I have a simple env as a flake.nix in the root of the Langchain repo (using that pyproject/poetry.toml):

Weird, override exists for it on unstable and nixos-24.05

nix-repl> python3Packages.tokenizers.override
{ __functionArgs = { ... }; __functor = «lambda @ /home/artturin/nixpkgs/lib/trivial.nix:895:19»; }

maybe offtopic but I have the same error with override with home-manager with https://github.com/nix-community/home-manager/pull/5930 when I do nix build .#test-espanso-basic-configuration

Not using callPackage (which applies makeOverridable) or makeOverridable will cause override to be missing

callPackage is used so neither of those are the problem https://github.com/NixOS/nixpkgs/blob/6e918e75e8bed152f24787aaad718649dc1963fe/pkgs/top-level/all-packages.nix#L4858

Hello! I'm trying to package a python app into a docker image with poetry2nix and then streamLayeredImage. I'm struggling to get my own code into the result. My code is organised like:

+ my_project
|- + ofd_runner
|   | ...
| pyproject.toml
| poetry.lock
| flake.nix

In flake.nix I do:

myEnv = pkgs.poetry2nix.mkPoetryEnv {
  projectDir = ./.;
  preferWheels = true;
};
dockerImage = pkgs.docker.streamLayeredImage {
          name = "ofd_user_code";
          tag = "latest";
          contents = [
            pkgs.bash
            pkgs.coreutils
            ofdUserCodeEnv
          ];
          config = {
            Cmd = [
              "${myEnv}/bin/dagster"
              "api"
              "grpc"
              "-h"
              "0.0.0.0"
              "-p"
              "4000"
              "-m"
              "ofd_runner"
            ];
            Env = [
              "DAGSTER_HOME=${dagsterHome}"
            ];
            WorkingDir = "${myEnv}/lib/python3.11/site-packages";
          };

In pyproject.toml, I have a set of dependencies which end up in my docker image, I can do import polars in the python in that docker image, but import ofd_runner won't work. Why is that? How do I get my own code in ofd_runner to land in my image?
