Python libs missing natively on Windows Arm64

These lists are designed to prioritize libraries that need to be fixed for Python development natively on WoA.
Based on this public list of top 1000 python packages by downloads. Orange 11% packages were investigated by automatic tests.

These lists are only the 11% of top 1000, the rest 89% already have native wheels or don't need them.

As of April 28, 2025, 52 packages failed to install while 72 succeeded with a local build via PyPi.

⬛ - No Win binaries / other hard block
❌ - No win_arm64 binaries/wheels available on PyPi
🟡 - Contribution was accepted, waiting for PyPi release
✅ - Globally available via PyPi

Contribution instructions

If you are already working on some of these libraries or just starting, here's how you can help others track your progress:

1. Request access to this repo in the comments.
2. Create a sub-issue with package name.
3. Copy all information from table and and sync any additional.
4. Work and share your progress in the issue. The issue can be closed only after the wheel lands on PyPi.

Libraries what not easy to build locally

Required noticable effort to build locally and contribute back to the community.
Some of the packages are blocked by others, making their build complexity unclear.

Libraries don't have wheels, but they are easy installed by PyPi

Potentially could be easily enabled due to a noncomplex build process.
This list was not processed; only granular updates related to previous table.
Still can be a blocker for other packages since local build process increses complexity of CIs and execution time.

cffi: python-cffi/cffi#164

[khmyznikov]

@lazka do you know why it's still not merged?

[lazka]

@lazka do you know why it's still not merged?

I assume because cffi hasn't had an active maintainer in quite a while.

[lowkeyrossi]

Hi @khmyznikov , I am really interested to contribute in enabling python wheels for WoA. Is there anything left for me?

[khmyznikov]

@lowkeyrossi definitely. Just scan the first table or second and take anything where no PRs. Create the sub issue with package name, assign yourself to it and share the progress there.

[HinTak]

FWIW, skia-python had WoA support in m138. The issue was closed kyamagu/skia-python#318 . It was dependent on numpy, which had 2.3 0 released with WoA support.

[khmyznikov]

@HinTak great! Do you work on something else from the lists?

[HinTak]

@HinTak great! Do you work on something else from the lists?

No, but you can see I contributed the numpy pull for WoA. (Because skia-python depends on numpy). That was my first ever contribution to numpy.

[lowkeyrossi]

Thanks, I am pretty good with nlp modules, so you can assign me tokenizer and tiktoken. I could see both depends on rust toolchain from CI.
