Switching from Pyenv to Uv

1. coppy

   15 year Python dev who usually adopts tooling slowly. Just do it, uv's absolutely worth it.

   I also use mise with it, which is a great combination and gives you automatic venv activation among other things.

   See, among other mise docs related to Python, https://mise.jdx.dev/mise-cookbook/python.html

   See also a Python project template I maintain built on mise + uv: https://github.com/level12/coppy

3. Poetry

   2 417 34,298 9.2 Python

   Python packaging and dependency management made easy

   

   Getting the right version of PyTorch installed to have the correct kind of acceleration on each different platform you support has been a long-standing headache across many Python dependency management tools, not just uv. For example, here's the bug in poetry regarding this issue: https://github.com/python-poetry/poetry/issues/6409

   As I understand it, recent versions of PyTorch have made this process somewhat easier, so maybe it's worth another try.

5. uv-virtualenvwrapper

   4 2 33 6.1 Shell

   A lightweight replacement for virtualenvwrapper when using uv

   

   I'm also only missing virtualenvwrapper-like support for central named venvs in uv.

   I'm too used to type virtualenvwrapper's `workon` and `mkvirtualenv` commands, so I've written some lightweight replacement scripts of virtualenvwrapper when using uv. Supports tab completion and implements only the core functionality of virtualenvwrapper:

6. hatch

   5 25 7,236 8.7 Python

   Modern, extensible Python project management

   

   We had to drop hatch for now, because it does not work well with uv's lockfiles. Someone opened an issue here: https://github.com/pypa/hatch/issues/1886. We use bare uv for now.
