Project mention: Uv is fantastic, but its package management UX is a mess | news.ycombinator.com | 2026-05-21
Scipy maintainer here, the main issue with the wheels was the Fortran77 that was SciPy throwing wrenches into the mix. With C/C++ self compilation should be quite straightforward. We (all Scientific Python packages) really worked hard on that.
From version 1.19 of SciPy there will be no need for fortran compilers (because we translated everything to C https://github.com/scipy/scipy/issues/18566) and then all becomes much easier in all platforms due to the large availability of C compilers in all platforms. Together with the Stable API developments in CPython the wheel clash issues "hopefully" will decrease gradually.

Cirq
Python framework for creating, editing, and running Noisy Intermediate-Scale Quantum (NISQ) circuits.
2. Full SDK installations. Qiskit, Cirq, PennyLane. These are serious tools for serious work. They're also 200MB+ installs with Python dependency chains, Jupyter notebooks, and a learning curve that assumes you already understand what you're trying to learn. That's backwards.
