openslide-bin

OpenSlide Python requires a copy of OpenSlide. You could install it from your package manager, or you could download binaries from the OpenSlide website. Either choice might be inconvenient, and depending on your package manager, it might get you an old version of OpenSlide.

openslide-bin is a pip-installable, self-contained build of OpenSlide for Linux, macOS, and Windows. It's built by the OpenSlide maintainers, ships the same binaries as the OpenSlide website, and has no dependencies you don't already have on your system. And it always has the latest version of OpenSlide.

Installing

Install with pip install openslide-bin. OpenSlide Python ≥ 1.4.0 will automatically find openslide-bin and use it.

openslide-bin is available for Python 3.9+ on the following platforms:

• Linux aarch64 and x86_64 with glibc 2.28+ (Debian, Fedora, RHEL 8+, Ubuntu, many others)
• macOS 11+ (arm64 and x86_64)
• Windows 10+ and Windows Server 2016+ (x64)

pip older than 20.3 cannot install openslide-bin, claiming that it is not a supported wheel on this platform. On platforms with these versions of pip (RHEL 8), upgrade pip first with pip install --upgrade pip.

Using

Use OpenSlide via OpenSlide Python. The OpenSlide Python API documentation will get you started.

Building from source

You should probably build OpenSlide from source instead.

The wheels are built by a custom script that runs Meson in builder containers. The source tarball includes all the source code and scripts, and the wheels are built directly from the tarball, but the build cannot be invoked from a PEP 517 frontend like build or pip. If wheels are not available for your system, building openslide-bin from source is not likely to help, and you'll likely have better luck installing OpenSlide from source directly.
