issues with dvc

[rdk31]

I'm trying to use dvc in mach-nix based development environment with no success. The issue seems to be that dvc uses its own python env and not the mach-nix's which causes scripts ran with it to fail because of the imports but I have no idea how to fix it. I'd be really grateful even for a hacky workaround patching the dvc's package somehow.

reproduction

shell.nix

let
  mach-nix = import (builtins.fetchGit {
    url = "https://github.com/DavHau/mach-nix";
    ref = "refs/tags/3.5.0";
  }) {};
in
mach-nix.mkPythonShell {
  requirements = ''
    numpy
    dvc
  '';
}

• enter the shell
• python -c 'import numpy' works
• dvc run -n "test" -f 'python -c "import numpy"' doesn't work
• executing which python in shell and with dvc run returns different python envs

dvc is in nixpkgs, so you don't need to involve mach-nix (and it's only a minor version out of date right now).

I tried using dvc from nixpkgs with the same result.
