The launchers were created using this simple launcher tree.

Even if the 圆4 emulation is present in the most recent Windows 10 圆4 version, the emulation introduces heavy performance penalties, which we will address in an upcoming post. Without the ARM64 launchers, the binaries are created using the 圆4 launchers and cannot be run on Windows ARM64 without 圆4 emulation. setuptools package required patching for the Windows ARM64 launchers so that the executables resulted from the build were created as ARM64 binaries.s etuptoolsand pip, although they could be successfully built, needed special attention in order to work correctly on ARM64: numpy and cffi required patching for ARM64. Out of the 25 packages, 23 were successfully built using the ARM64 Python versions on Windows 10 ARM64. Here are the most used 25 Python packages in the past 365 days (as of December 2020) according to Besides that, the real issues typically arise when the package includes native code which needs to be compiled with an ARM64 C/C++ compiler on Windows as part of the setup process unless wheel files are made available on Pypi. The creation of binary launcher is a different story though, as we will see in the next section. checking for os.uname()) there are no reasons for them not to work. Even at runtime, unless they rely on some specific CPU architectural feature (e.g. Generally speaking, packages that are 100% Python and do not include native code, have no setup issues on ARM64 either.

All packages were either install using pip with the following flags “–force-reinstall –no-binary :all:” or using “ python setup.py install“. We used GitHub actions to create reproducible builds leveraging a parameterized workflow. We are going to look at three main scenarios: multi-purpose, scientific and DevOps. No one desires to spend time rewriting their application just to support another architecture or use non-upstreamed package sources, which are hard to maintain and non-trivial to test.įor the sake of this post, we are going to use Python 3.9, being the latest stable release. Package support is critical for Python developers in order to port their work to this new architecture, especially when relying on third party packages from Pypi or other sources as it usually happens. This post is meant to snapshot the current state of the art of the Python ecosystem on Windows ARM64, focusing on one main area: package support. According to, Python is ranked first in Google’s search popularity. Python is an interpreted programming language that is used in multiple fields, ranging from education, scientific purposes to DevOps and cloud infrastructure.
