For what it's worth, you can install pixi with Cargo. The current invocation is:

  cargo install --locked --git https://github.com/prefix-dev/pixi.git pixi

I try new versions of pixi from time to time because I have a project that depends on LAVIS and EasyOCR. My default project-management tool, Poetry, has problems with PyTorch. Right now, I use pip-tools for the project. While Conda worked, I didn't like the tooling that much. What is currently blocking me from using pixi is the PyPI integration (https://github.com/prefix-dev/pixi/issues/1295). I can evaluate pixi in earnest when it is solved.
