Mappings in collections is depricated since 3.3 and removed in 3.10.

in 3.10 its failing like this:

ImportError: cannot import name 'Mapping' from 'collections' (/software/miniconda/envs/pytroll/lib/python3.10/collections/__init__.py)

In 3.3 onwards Mapping is moved to
https://docs.python.org/3.9/library/collections.abc.html#module-collections.abc

This module needs to be updated accordingly

Hmm, this seems to be already fixed in the main branch: https://github.com/pytroll/pytroll-schedule/blob/main/trollsched/utils.py#L28
