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 Pre-release Python binary wheels and dependencies for unofficial pre-release of packages for testing.

sci-kit learn	Investigation Done	Numpy Scipy Fortran		https://github.com/scikit-learn/scikit-learn/pull/20997	flang dlls should be feed into this package, which is a manual step now Test Results 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		Pull Requests https://github.com/winlibs/libiconv/pull/11 https://github.com/mhils/libxml2-win-binaries/pull/21 https://github.com/lxml/lxml/pull/326 https://github.com/lxml/libxml2-win-binaries/pull/1/

Pywin32	Released			https://github.com/mhammond/pywin32/pull/1793
Maturin	Released			https://github.com/PyO3/maturin/pull/674	Notes 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.
