Actually, only the second one, because I already had pipx (https://pipx.pypa.io/ — a wrapper for pip that does basic virtual environment management) installed.
Can you name some specific things in Python you have tried to use, and give more concrete descriptions of how you tried to set them up?

opencv-python
Automated CI toolchain to produce precompiled opencv-python, opencv-python-headless, opencv-contrib-python and opencv-contrib-python-headless packages.
Extra stuff like type checking and annotations are definitely not the reason why python became that popular and widely adapted and used, but it certainly doesn't hurt to add and use them.
To be clear, I'm not expecting people to start adding generics to their quick hacked together Python scripts (in fact please don't do that). Instead, if you're building a library or maintaining a larger Python codebase, a lot of these start becoming very useful. A lot of the typing features I mentioned are already used by Python under the hood, and that a lot of Python developers just take for granted.
Case in point, the python-opencv (https://github.com/opencv/opencv-python) library has basically no types and it's an absolute pain to work with.
BTW thats a really good SO thread, thanks for linking it!

I work on Harbor (https://github.com/av/harbor), it is a project to save hours when setting up LLMs locally.
I pre-integrated over 50 different LLM-related projects, added a nice CLI and a Desktop app on top to manage the configs.

I know far too much about python packaging while only knowing a little about it.
I agree it’s hell. But I’ve not found many comprehensive packaging solutions that aren’t gnarly in some way.
IMHO the Python Packaging community have done an excellent job of producing tools to make packaging easy for folks, especially if you’re using GitHub actions. Check out: https://github.com/pypa/cibuildwheel
Pypa have an extensive list of GitHub actions for various use cases.
I think most of us end up in the “pure hell” because we read the docs on how to build a package instead of using the tools the experts created to hide the chaos. A bit like building a deb by hand is a lot harder than using the tools which do it for you.
