The whole point of uv is to solve the nightmare that is running a script with the right version of python with the right dependencies

"Just use the system python" gets you right back to the start (oh no! It didn't parse because it used python 3.11 features and I'm still on 3.5)

> And python is available on almost any system

This is actually the root of all Python problems, by it believing it has a right to be a core part of the operating system all the package design choices treat their installation like they're the only thing running on the machine when the realities of Python packages are they all rely on very specific versioning from the interpreter to between the packages so the idea of having a canonical version of pytorch that all your projects run on just doesn't exist.

Python is not a globally available thing. I was really surprised when I setup Kubuntu 24.04 and found it missing. And now you can do `uv run --python=<version> ...` and have all that automatically handled on a case by case basis.

uv can seemlessly get the correct python binary on demand. It would be a pain to get, say, python 3.9 or python 3.14 on my system. Making sure uv is installed actually seems to be less of an issue, but of course this varies.
