Changes/NumPy2

NumPy2

This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

Update the numpy package from 1.x to 2.x (1.26.4 to 2.1.3 currently).

Owner

• Name: Gwyn Ciesla
• Email: gwync@protonmail.com

Current status

• Targeted release: Fedora Linux <VERSION>
• Last updated: 2024-11-11
• [Announced]
• [<will be assigned by the Wrangler> Discussion thread]
• FESCo issue: <will be assigned by the Wrangler>
• Tracker bug: <will be assigned by the Wrangler>
• Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

Updating numpy from the 1.x to 2.x series will Just Work for some packages. Those using the C API will need to be rebuilt. Additionally, many packages are pinned to numpy < 2, and these will need to be loosened.

Feedback

I've experimented with this in copr, as well as tracked updates to a few packages in preparation for this. One example is scipy, which was recently updated to a version supporting numpy2, and this will reduce the number of impacted packages.

Benefit to Fedora

In addition to tracking upstream and receiving more up-to-date fixes and security updates, numpy2 brings many improvements to the library:

Scope

• Proposal owners:

Update numpy2 package to 2.1.x in f43 immediately after f42 mass branching. Help rebuild and patch impacted packages as needed.

• Other developers:

Rebuild and patch impacted packages. Most will only require a pin adjustment and/or rebuild.

• Release engineering: #Releng issue number

• Policies and guidelines: N/A (not needed for this Change)

• Trademark approval: N/A (not needed for this Change)

• Alignment with the Fedora Strategy:

Early Testing (Optional)

Do you require 'QA Blueprint' support? Y/N

How To Test

Run applications that use numpy or one of it's dependencies.

User Experience

End users should not notice any changes. Python developers will need to rebuild C API code against numpy2, and can then take advantage of new features.
