Import issue with astropy 6.0

[segasai]

Hi,

The gala imports fail with astropy 6.0 due to a function that was removed in astropy
astropy/astropy@bb7de42

In [1]: import gala
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
Cell In[1], line 1
----> 1 import gala

      5 import sys

----> 9 from ._astropy_init import *
     11 # Enforce Python version check during package import.
     12 # This is the same check as the one at the top of setup.py
     13 __minimum_python_version__ = "3.7"

File ~/pyenv310/lib/python3.10/site-packages/gala/_astropy_init.py:21

     24     ConfigurationDefaultMissingWarning)
     26 # Create the test function for self test
     27 from astropy.tests.runner import TestRunner

ImportError: cannot import name 'update_default_config' from 'astropy.config.configuration' (/home/skoposov/pyenv310/lib/python3.10/site-packages/astropy/config/configuration.py)

TBH it's not clear to me what _astropy_init.py's purpose is anyway...

Thanks

Yes I need to redo the packaging layout of gala - this is mostly vestigial! Thanks for the issue - I just opened #345 which should hopefully fix the compatibility with astropy 6.0!

Thanks for the quick fix! I'll try to test it soonish.
(I've switched back to astropy5.3 for the time being)

Ah ok, no worries. I just found another issue that will take a little longer to solve, so I'll let you know when things are actually working again!
