Wheels containing OpenBLAS
- The primary purposes of the scipy-openblas32 and scipy-openblas64 wheels are:
- (a) to use them as build and runtime dependencies in CI and local development for NumPy and SciPy
- (b) to be vendored into NumPy and SciPy wheels
- (c) possibly, in the future, being used as runtime dependencies for NumPy and/or SciPy.
- Other Python projects are also welcome to use these wheels for 1(a) and 1(b).
- Please note that there is no strong guarantee of backwards compatibility
for the symbol names nor the small Python API shipped in the wheels to
enable linking against the shared library. If you want to use them, you
should probably use
==pins in the relevant CI/lock files, like NumPy and SciPy also do.
- Please note that there is no strong guarantee of backwards compatibility
for the symbol names nor the small Python API shipped in the wheels to
enable linking against the shared library. If you want to use them, you
should probably use
OpenBLAS library build process
First, OpenBLAS is built using build_lib in tools/build_steps.sh (on
posix in a docker and drectly on macos) or tools/build_steps_windows.sh on windows.
Then the shared object and header files are used to build the
wheel via tools/build_prepare_wheel.sh and pip build wheel.
If the build is on the main branch, the wheels are uploaded to
https://anaconda.org/scientific=python-nightly-wheels/scipy_openblas32 and
https://anaconda.org/scientific=python-nightly-wheels/scipy_openblas64 via
tools/upload_to_anaconda_staging.sh.
There are workflow triggers for repo admins. They can trigger a testpypi build or a pypi build with the publish workflow, which will upload the wheels using trusted publishing. In order to publish to PyPI, there must be a tag at the HEAD of the branch used to publish. After merging a PR, be sure to update to main and use annotated tags:
git checkout main; git pull
git tag -a v0.3.31.126.4 -m"fixed something"
The wheel is self-contained, it includes all needed gfortran support libraries. On windows, this is a single DLL.
Buildtime
get_include_dir(),get_lib_dir()andget_library()for use in compiler or project argumentsget_pkg_config()will return a multi-line text that can be saved into a file and used with pkg-config for build systems like meson. This works around the problem of relocatable pkg-config files since the windows build uses pkgconfiglite v0.28 which does not support--define-prefix.
Runtime
- importing will load openblas into the executable and provide the openblas symbols to the exectuable.
