Hi Grant, Thank you for putting together the Windows on ARM Python Ecosystem Report. Apologies for missing this week's call. I went through the report (21-Oct) and compared it against our tracker. A few blocked libraries in the report are captured in our tracker as well. Below are the packages where QC already has work in progress - 1. Packages where we already have an open PR or active work (needs maintainer traction) Package PR / work Status pyarrow apache/arrow #48539<https://github.com/apache/arrow/pull/48539> Waiting on the abi3 work; maintainers short of review time tiktoken openai/tiktoken #501<https://github.com/openai/tiktoken/pull/501> Open; no maintainer response since March confluent-kafka confluent-kafka-python #2190<https://github.com/confluentinc/confluent-kafka-python/pull/2190> Open; CLA signed, no review yet opencv-python(-headless) opencv-python #1143<https://github.com/opencv/opencv-python/pull/1143> Planned for OpenCV 5.0; under discussion with maintainers. setproctitle py-setproctitle #164<https://github.com/dvarrazzo/py-setproctitle/pull/164> Open; no response dbt-extractor dbt-labs/dbt-extractor #142<https://github.com/dbt-labs/dbt-extractor/pull/142> Open, no reviews fastuuid fastuuid/fastuuid #63<https://github.com/fastuuid/fastuuid/pull/63> Open; no reviews google-crc32c google/crc32c #73<https://github.com/google/crc32c/pull/73> (approved, not merged) Wheel request now at google-cloud-python #16516 torch / torchvision PyTorch perf PRs + benchmarks We are trying to establish communication with Meta. temporalio Working wheel built on fork<https://github.com/Harishmcw/sdk-python/tree/test-ci> CI Blocked on cryptography wheels jpype1 Builds locally Blocked on Azure Pipelines having no Windows ARM64 agents 2. Packages where we can support by opening PRs * PyMuPDF: ARM64 wheels shipped in 1.28.2 but were dropped in 2.0. We can raise an issue/PR to restore them. * pyyaml, snowflake-connector-python: ARM64 wheels are missing only for some Python versions; small CI PRs should cover them. * fonttools, chardet, isort, pytokens, dulwich, simplejson, magika: candidates for small CI PRs (We can work on these and add support for CI if required) 3. Blocked: we cannot progress without maintainer/vendor support * brotli: Python wheels are built in google/brotli-wheels, which has no ARM64 entry, and the maintainer is unresponsive. * cryptography (fixed, waiting for the 51.0 release) and lightgbm (fixed, no release since July): these block our PyArrow tests, Optuna, Pyrit and yasa. * debugpy and awscrt: need an ARM64 build agent in Microsoft's and AWS's internal release pipelines respectively.

Is this the sort of data you’re looking for? This is for the top 1000 packages. It is easy to adapt the search criteria from here and also dig into more details on the blockers. Everything here is based on public data. It isn’t an exhaustive search. https://claude.ai/artifact/KiRoGa9rGDtwMKTggsaWYc Grant -- Grant Likely Arm Fellow and CoreCollective Technical Chair IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
