I'm sure it's true and all. But I've been hearing the same claim about all those tools uv is intended to replace, for years now. And every time I try to run any of those, as someone who's not really a python coder, but can shit out scripts in it if needed and sometimes tries to run python software from github, it's been a complete clusterfuck.

So I guess what I'm wondering is, are you a python guy, or are you more like me? because for basically any of these tools, python people tell me "tool X solved all my problems" and people from my own cohort tell me "it doesn't really solve anything, it's still a mess".

If you are one of us, then I'm really listening.

I'm one of you.

I'm about the highest tier of package manager nerd you'll find out there, but despite all that, I've been struggling to create/run/manage venvs out there for ages. Always afraid of installing a pip package or some piece of python-based software (that might muck up Python versions).

I've been semi-friendly with Poetry already, but mostly because it was the best thing around at the time, and a step in the right direction.

uv has truely been a game changer. Try it out!

As a Ruby guy: uv makes Python feel like it finally passed the year 2010.

Don’t forget to schedule your colonoscopy as a Ruby guy

I’m a “Python guy” in that I write Python professionally, but also am like you in that I’ve been extremely underwhelmed by Portry/Pipenv/etc.

Python dependencies are still janky, but uv is a significant improvement over existing tools in both performance and ergonomics.

As a developer: it basically solved all of my problems that could be solved by a package manager.

As an occasional trainer of scientists: it didn't seem to help my students.

It installs stuff super fast!

It sadly doesn’t solve stuff like transformer_engine being built with cxx11 ABI and pytorch isn’t by default, leading to missing symbols…

[OrderlyTiamat]

I'm (reluctantly) a python guy, and uv really is a much different experience for me than all the other tools. I've otherwise had much the same experience as you describe here. Maybe it's because `uv` is built in rust? ¯\_ (ツ)_/¯

But I'd also hesitate to say it "solves all my problems". There's plenty of python problems outside of the core focus of `uv`. For example, I think building a python package for distribution is still awkward and docs are not straightforward (for example, pointing to non-python files which I want to include was fairly annoying to figure out).

[OoooooooO]

As a mainly Python guy (Data Engineering so new project for every ETL pipeline = a lot of projects) uv solved every problem I had before with pip, conda, miniconda, pipx etc.

It doesn't handle python version management, it only handles pip. It doesn't solve bundling Python.

It does handle python version management: https://docs.astral.sh/uv/concepts/python-versions/

[beacon294]

That's great news, I'll have to try to replace pyenv (again).

[J_Shelby_J]

Isn’t UV essentially cargo for python?

[adastra22]

Somewhat literally so. It is written in Rust and makes use of the cargo-util crate for some overlapping functionality.

[rossant]

I know, but uv truly is different.
