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.

Released in 1.15.0

 

 

added support for building cffi on windows on arm machines (!107) · Merge requests · PyPy / cffi · GitLab

 

scipy

Investigation Done

  • Numpy

  • OpenBLAS

  • Fortran compiler

 

 

Blocked due to fortran compiler avaiability

sci-kit learn

Investigation Done

 

  • Numpy

  • Scipy

  • Fortran

 

FIX Fixes test for checking gitignore and Cython templates by gaborkertesz · Pull Request #20997 · scikit-learn/scikit-learn

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

 

https://github.com/apache/arrow/pull/11383

 

greenlet

Merged.

 

 

https://github.com/python-greenlet/greenlet/pull/271

 

Pillow

Released in 9.1.0

  • lcms2

  • freetype

  • zlib

  • libwebp

  • libjpeg

  • libpng

  • libimagequant

  • libtiff

  • openjpg

  • fribidi

 

https://github.com/python-pillow/Pillow/pull/5811

A tale of a dependency chain: Pillow and the crew

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

 

 

https://github.com/mhammond/pywin32/pull/1793

 

Maturin

Released

 

 

https://github.com/PyO3/maturin/pull/674

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

 

To build,

maturin develop --release

To run tests,

python runtests.py

All tests should be passing with all of the PRs
