"TypeError: 'ABCMeta' object is not subscriptable " when importing xmip.preprocessing

[sspaulo]

Hello,

I am encountering a TypeError: 'ABCMeta' object is not subscriptable when trying to import rename_cmip6 from the xmip.preprocessing module.
I created a new separate enviroment to use xmip:

Python version: 3.8.18
Packages versions:
xmip: 0.7.1
cf_xarray: 0.8.6
xarray: 2022.11.0
dask: 2023.5.0
fsspec: 2023.10.0
gcsfs: 2023.10.0
numpy: 1.23.3
pandas: 1.5.0
aiohttp: 3.9.0

Has anyone come across this issue before ? Any help is appreciated.
Thank you !

Hi @sspaulo. Sorry for missing this issue. Is this still relevant? If so could you post a full error trace so we can see where this error occurs?

I had the same in a python 3.8 build, I think the issue is in cf_xarray, downgrading to 0.7.7 fixed the issue for me. I think cf_xarray has silently dropped the python 3.8 support at some point.

Nice catch @JoranAngevaare!

I think we should maybe consider bumping our python requirement too? In the same vein we could consolidate our setup.py/setup.cfg into the pyproject.toml?
