Description

I have py38-astropy@5.3 installed and when I try to import the cosmology sub-package, it fails. Here's the code and output:

Seans-Work-Macbook-Pro:~ sean$ python3.8
Python 3.8.17 (default, Jun 10 2023, 11:16:23) 
[Clang 14.0.3 (clang-1403.0.22.14.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import astropy.cosmology as cosm

Judging by this commit to the affected file, astropy 5.3 drops support for python 3.8. Using pip to force install astropy version 5.2.2 in my user directory solves the problem. So py38-astropy should probably be pinned to version 5.2.2, unless this is an unintentional bug in astropy.

I didn't catch that in the update notes. It was hidden in the full notes.

Will fix!
