Just to clarify for anyone who isn't aware, the "compiling issues", at least historically, have been that Alpine uses musl, and PyPI's manylinux wheels are built against old glibc versions. So stuff like numpy that would trivially and quickly install from whl on glibc distros (like a bare-bones Ubuntu image) trigger compilations and the installation of build-only dependencies/toolchains on Alpine. That said, it looks like as of late-2021, at least some projects are offering musllinux wheels as well, per the discussion here: https://github.com/pypa/manylinux/issues/37 https://github.com/pypa/manylinux/issues/37 (not numpy yet, though: https://pypi.org/project/numpy/#files https://pypi.org/project/numpy/#files) Here's a longer version of the above, originally published in 2020, but with an update regarding PEP 656: https://pythonspeed.com/articles/alpine-docker-python/ https://pythonspeed.com/articles/alpine-docker-python/
