Dear Debian Pythonistas,

the NumPy 2 transition is now on its way, and while many packages
seem to rebuild quite nicely, there are a few gotchas I'd like to
point out, so everyone does not need to figure this out on their
own.

1. We did some work to improve cross build support in NumPy [1],
which means that dh-sequence-numpy3 can no longer pull the native
Python module. If you encounter weird ModuleNotFoundErrors, you
probably need to add python3-numpy as an explicit dependency.

2. The NumPy module hierarchy has changed in a way that breaks code
trying to compute the include path to the NumPy headers on its own.
If you encounter build errors where GCC fails to find headers such
as numpy/arrayobject.h, make sure you use the intended API to
configure the build [2].

3. Lintian has yet to catch up with the changed virtual package for
the NumPy ABI [3], so you might see a few spurious "missing-dependency-on-numpy-abi" diagnostics.


Cheers
Timo

It would have been nicer to upload to experimental first, see the
excuse page and find bugs accordingly. Uploading directly to
unstable for this kind of high profile package is NOT the way to
go.

I agree, which is why NumPy 2 has been in experimental for months,
and the transition is coordinated with the Release Team.


Cheers
Timo

Hi Thomas,

* Thomas Goirand <[email protected]> [2025-01-29 08:13]:

If so, how come there's so many failures in unstable? Shouldn't they
have been addressed before the upload to unstable? >https://qa.debian.org/excuses.php?package=numpy

Please give Timo some more time, the binNMUs are not done yet:

https://release.debian.org/transitions/html/numpy2.html

And the transition is coordinated here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1082237

Given the complexity and entanglement of numpy I think it was expected
that the transition to the new ABI version would not be fast.

Cheers Jochen
