about "Also, do you use pip, conda or poetry?": mostly pip. I only use conda micromamba if (1) I don't want to compile my dependencies from source, (2) I want to avoid PyTorch or tensorflow 800 megabyte wheels, (3) or I want to use fine-grained feature selection beyond what pip supports, such as GPU stuff. workflow tools (like Poetry, Hatch, PDM, Rye) are for development and not for production, IMHO
