ImportError: cannot import name 'cascaded_union' from 'shapely.ops'

[ehsantaghizadeh]

Hello,

I tried following the steps in the documentation here:

https://salem.readthedocs.io/en/latest/plotting.html#plotting-with-salem

However, when running the line:

ds.T2C.isel(time=1).salem.quick_map();

I encountered the following error:

ImportError: cannot import name 'cascaded_union' from 'shapely.ops'
(/home/username/miniconda3/envs/geocat/lib/python3.12/site-packages/shapely/ops.py)

Could you please advise on how to resolve this issue?

Thank you.

Hi, `casacaded_union` was removed from shapely with version 2.0.0.  For now you can restrict the shapely version to <2.0.0 Kind regards, Ben Edit: Could you still provide a full stacktrace and package version list please?

Can you send the full traceback (error message)? Salem does not use or import cascaded_union, which makes me wonder if it has anything to do with salem at all.
