Subject: insilicoseq: autopkgtest regression with NumPy 2.4
Date: Tue, 17 Mar 2026 11:46:00 +0100
X-Generator: mass-bug from devscripts 2.26.6

Source: insilicoseq
Version: 2.0.1-2
Severity: important
User: debian-python@lists.debian.org
Usertags: numpy2.4

Dear maintainer,

According to https://ci.debian.net data, your package insilicoseq has an
autopkgtest regression with numpy.

The following architectures failed: amd64, arm64.

Hopefully relevant excerpt from
https://ci.debian.net/packages/i/insilicoseq/unstable/amd64/69506600/
follows:

 86s test/test_bam.py::test_to_model FAILED                                   [ 23%]
 88s test/test_modeller.py::test_kde_qualities FAILED                         [ 65%]
 88s =================================== FAILURES ===================================

 88s E           numpy.linalg.LinAlgError: The data appears to lie in a lower-dimensional subspace of the space in which it is expressed. This has resulted in a singular data covariance matrix, which cannot be treated using the algorithms implemented in `gaussian_kde`. Consider performing principal component analysis / dimensionality reduction and using `gaussian_kde` with the transformed data.
