scikit-survival 0.17.2 released

I’m pleased to announce the release of scikit-survival 0.17.2. This release fixes several small issues with packaging scikit-survival and the documentation. For a full list of changes in scikit-survival 0.17.2, please see the release notes.

Most notably, binary wheels are now available for Linux, Windows, and macOS (Intel). This has been possible thanks to the cibuildwheel build tool, which makes it incredible easy to use GitHub Actions for building those wheels for multiple versions of Python. Therefore, you can now use pip without building everything from source by simply running

pip install scikit-survival

As before, pre-built conda packages are available too, by running

 conda install -c sebp scikit-survival

Support for Apple Silicon M1

Currently, there are no pre-built packages for Mac with Apple Silicon M1 hardware (also known as macos/arm64). There are two main reasons for that. The biggest problem is the lack of CI servers that run on Apple Silicon M1. This makes it difficult to systematically test scikit-survival on such hardware. Second, some of scikit-survival’s dependencies do not offer wheels for macos/arm64 yet, namely ecos and osqp.

However, conda-forge figured out a way to cross-compile packages, and do offer scikit-survival for macos/arm64. I tried to adapt their conda recipe, but failed to achieve a working cross-compilation process so far. Cross-compiling with cibuildwheel would be an alternative, but currently doesn’t make much sense if run-time dependencies ecos and osqp do not provide wheels for macos/arm64. I hope these issues can be resolved in the near future.
