Welcome

Some logistics:

  • Everyone should have gotten a badge
  • We'll be sharing catering with SciPy tutorials
  • We have enough leftover funds for a workshop dinner (need to find a place!)

Who we are

  • Around 18 of us here
  • Wide range of prior knowledge, from novice to expert!

It's hard to target everyone! So let's try a few things:

  • Focus on interactivity - questions and talking is good (workshop)
  • Will have a mix of overviews and in-depth dives
  • Everyone might see some new stuff!
  • Groups can break out to work on stuff if you want

What we'll cover

  1. Basic Packaging — venvs, uv, pyproject.toml, publishing
  2. Compiled — C++ bindings, Rust, building wheels everywhere
  3. scikit-build-core — CMake-driven builds, stable ABI, editable installs
  4. Other Tools — plugins, conda-forge, distros
  5. Interesting topics — free-threading, lazy imports, AI, and CUDA

And we have an open hack on day 2!

Prerequisites

Install ahead of time

  • uv — package manager
  • pixi — conda package manager
  • A system compiler

Handy (via uv tool install)

  • prek — linter runner
  • nox — task runner

The first talk walks through setup in detail.

How this works

  • Slides frame each topic; the book has the full details
  • Every chapter links to its slides
  • Follow along hands-on workspace (and exercises)
  • Ask questions any time!

Henry: material preparation

  • scikit-build-core 1.0 took priority for a while
  • A lot of my material was collected from other things I've written
  • Slides were summarized from page content
  • If you get bored with the plain slides, go to https://scikit-build.org, dark mode, and scroll up and down. :)
