Hey @wenboyu0803 apologies for the delayed response. At the moment, I can't reproduce your error as I am (for some weird reason) getting multiprocessing errors when fitting a cumulative model. Once I get this resolved, I will circle back here.

Hi @wenboyu0803 do you have a minimum example I can run? Also, do you know which versions of arviz, bambi, and xarray you're running?

[tomicapretto]

xarray.Coordinates were introduced in v2023.08.0 of xarray (see https://github.com/pydata/xarray/releases/tag/v2023.08.0). I think you are using an old version.

hi @tomicapretto
i will check the version of xarray these days.
if it still does not work, i will show you my data.
Thanks.
