Packages

This section summarises the progress of porting python packages for windows on arm64 platform.

A large number of python packages have platform-specific code and they need to be ported explicitly for new platforms such as windows on arm64.

Please see our investigation into python packages that need porting for win/arm64 here

Please checkout https://linaro.atlassian.net/wiki/spaces/WOAR/pages/28657844879 for unofficial pre-release of packages for testing.

Python Package	Status	Dependencies	CI/CD	Commit/PR	Notes

Python Package	Status	Dependencies	CI/CD	Commit/PR	Notes
setuptools	Win/ARM64 support Released in 57.4.0			https://github.com/pypa/setuptools/commit/f15f814e9e82c2343280e8f62360f12b3023eb5f
setuptools	Windows Launcher support Released in in 58.2.0			https://github.com/pypa/setuptools/pull/2758/	https://github.com/pypa/setuptools/issues/2757
pip	Released 21.3	distlib
distlib simple_launcher	Released in 0.3.3			https://bitbucket.org/pypa/distlib/pull-requests/5?t=1 https://bitbucket.org/vinay.sajip/simple_launcher/pull-requests/1
numpy	Released in 1.21.2	Fortran compiler Setuptools	Azure pipelines for release (Linux only) Github actions for CD		Generic issue for numpy, conflicting with coming Pythong 3.10:
cffi	Released in 1.15.0
scipy	Investigation Done	Numpy OpenBLAS Fortran compiler			Blocked due to fortran compiler avaiability
sci-kit learn	Investigation Done	Numpy Scipy Fortran			flang dlls should be feed into this package, which is a manual step now unit-tests mostly passed `2 failed, 21039 passed, 1097 skipped, 61 xfailed, 38 xpassed, 4005 warnings`
pandas	No porting required.	numpy		-	if numpy is installed manually for win-arm64, then with “--no-build-isolation” flag, the installation will be successful
lxml	Released	zlib iconv libxml2 libxslt
pyarrow	Release v6.0.0	arrow
greenlet	Merged.
Pillow	Released in 9.1.0	lcms2 freetype zlib libwebp libjpeg libpng libimagequant libtiff openjpg fribidi			pip install by source doesn’t work, because Pillow has its own logic build from source that is not implemented in its setup.py, so win-arm64 specific wheel file release is needed
Pywin32	Released
Maturin	Released				Build `python setup.py install` Alternatively can build with cargo command directly `cargo run -- build --release -b bin --target aarch64-pc-windows-msvc --no-sdist --cargo-extra-args="--no-default-features" --cargo-extra-args="--features log,upload,human-panic"` The above command works on GitHub CI on x64 machine but seems to fail on arm64 as the cargo-extra-args seems to be ignored. Test Remove rustls from cargo.toml cargo run -- build -i python -m test-crates/pyo3-mixed-submodule/Cargo.toml pip install --force-reinstall --no-index --find-links test-crates/pyo3-mixed-submodule/target/wheels pyo3-mixed-submodule pytest test-crates/pyo3-mixed-submodule/tests/ This seems to be the test on CI and test pass on win/arm64 but doesn't look like the right test set.
Pywinpty	Released	winpty gyp		https://chromium-review.googlesource.com/c/external/gyp/+/3268692 https://chromium-review.googlesource.com/c/external/gyp/+/3268691	To build, `maturin develop --release` To run tests, `python runtests.py` All tests should be passing with all of the PRs
cibuildwheel	Released
grpcio	Released
skbuild (sci-kit build)	Released in 0.13.0
pycryptodome	Blocked
azure-uamqp-python	Merged
TensorFlow	In Progress
PyTorch	Merged
matplotlib	Merged
cython-blis	Released
CMake	Released by 3.22.4	sci-kit build			x86 emulated CMake is deployed for win-arm64 by this change, so as soon as official native win-arm64 CMake is released, this should be updated
mysqlclient	blocked on dependant proprietary 3rd party library:
OpenCV	Merged
