Hi Adrian, * Adrian Bunk <[email protected]> [2025-11-10 21:51]:
Yes, there is. After the package split to improve cross build support (see [1]), python3-numpy needed a hard dependency on python3-numpy-dev to remain backwards and upstream compatible. As the python3-numpy-dev is technically stand-alone (it can be used to build C extensions without python3-numpy), the reverse depend was downgraded to avoidOn Fri, Oct 24, 2025 at 08:21:34PM +0200, Matthias Klose wrote:Package: src:opencv Version: 4.10.0+dfsg-6 Severity: serious Tags: sid forky ftbfsSeen that in an Ubuntu build, not yet sure why it doesn't ftbfs in Debian. -- Found PythonInterp: /usr/bin/python3 (found suitable version "3.13.9", minimum required is "3.2") -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.13.so (found suitable exact version "3.13.9") Traceback (most recent call last): File "<string>", line 1, in <module> import numpy; print(numpy.get_include()) ^^^^^^^^^^^^ ModuleNotFoundError: No module named 'numpy' and indeed, there is no explicit b-d on python3-numpy, while you add one as a dependency explicitly. Please also add it as a build dependency.Is there a good reason why python3-numpy-dev only recommends python3-numpy? It feels wrong that the build dependency on dh-sequence-numpy3 does not pull in python3-numpy.
a circular dependency.
