Changes/NumPy2

NumPy2

Summary

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

Owner

• Email: gwync@protonmail.com

Current status

• Targeted release: Fedora Linux 42
• Last updated: 2024-12-16
• Announced
• Discussion thread
• FESCo issue: #3295
• Tracker bug: #2332647
• 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:

https://blog.scientific-python.org/numpy/numpy2/

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:

Upgrade/compatibility impact

Successfully rebuilt packages should not have any compatibility issues.

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.

Contingency Plan

• Contingency mechanism: Depending on scope of packages not fixed, Gwyn will either help fix those packages, or create a compat package and patch packages to use that.
• Contingency deadline: Beta Freeze
• Blocks release? No
