Reproducible work environments for data scientists using Nix
summary
Argues that Nix makes development environments deterministic by treating packages as immutable and declarative, demonstrates a small project that uses Nix expressions plus a pip-exported requirements.txt to fix a mismatched numpy version, and shows the workflow: nix-shell creates a reproducible shell, a venv installs locked Python deps from PyPI, and pip list confirms the intended versions. Uses Nix, nix-shell, Poetry/UV/virtualenv and validates that the setup works end to end.
