import gala.coordinate

What is the problem?

I have download the package astronomy-python of https://datacarpentry.org/astronomy-python/
The installation is OK but when I want to check my installation, and i try :

'import gala.coordinates as gc'

I receive this message:

ImportError: cannot import name 'update_default_config' from 'astropy.config.configuration' (/home/pierre-bernard/anaconda3/envs/AstronomicalData/lib/python3.12/site-packages/astropy/config/configuration.py)

Do you have an idea ? thanks

Can you please let me know what OS you are using and the version of astropy and gala that you have installed? You can access this information by starting up a python session and typing:

import astropy
print(astropy.__version__)
import gala 
print(gala.__version__)

It is possible the gala import will produce the same error you got above, in which case don't worry about getting the version.

I followed the advice of adrian price-whelan on Slack. I have downloaded the last version of GALA (development version) , with
pip install git+https://github.com/adrn/gala

...and it run perfectly !
My astropy.version is 6.0.0
and my new gala version is 1.7.2.dev45+g3aab5f14

Thank's . It's a very great job. I plan to use it in my Astronomical Association in France ( after translated)

Thanks for sharing your solution @pbtoubol. If you teach this lesson is would be great to submit it as a self organized workshop to the Carpentries so that we can track its use.
