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.
As of Dec 15, 2025, these lists are only the 7% of top 1000, the rest 93% already have native wheels or don't need them.
⬛ - 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:
- Request access to this repo in the comments.
- Create a sub-issue with package name.
- Copy all information from table and and sync any additional.
- 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 increases complexity of CIs and execution time.
