The main options for using non-nixpkgs python module versions are [Mach-nix: Create python environments quick and easy](https://discourse.nixos.org/t/mach-nix-create-python-environments-quick-and-easy/6858) or [poetry2nix](https://github.com/nix-community/poetry2nix), and [pypi2nix](https://github.com/nix-community/pypi2nix). You could also make an overlay in your nix-shell and override the python module versions to match the requirements.txt, but I would check out one of the above tools.
