Wheels are the standard binary format for distributing Python packages. See pythonwheels.com.
Any package that uses C, C++, or Rust extensions needs a wheel for each platform and Python version. Windows/ARM64 is a new platform that needs wheels.
Without wheels, users will have to compile from source, which requires a toolchain and a working build script.
If a package hasn't published an ARM64 wheel for Windows, it's a good indicator that it hasn't been tested and probably won't work.
This site shows the top 1000 most-downloaded packages on PyPI showing which have been uploaded as wheel archives.
Windows/ARM64 wheels have a Platform tag of win-arm64
.
Packages that are known to be deprecated are not included (for example, distribute). If your package is incorrectly listed, please create a ticket.
Take a look at the CI-build-wheel project for an easy way to create Wheels for every platform, including Windows ARM64
