Bug#1029593: nibabel: (armel autopkgtest) needs update for NumPy 1.24

Show all headers | View raw

Source: nibabel
Version: 4.0.2-1
Severity: serious
User: debian-ci@lists.debian.org
Usertags: needs-update

Hi Maintainer

The autopkgtests of nibabel fail with NumPy 1.24 on armel [1].  I've
copied what I hope is the relevant part of the log below.

Regards
Graham
