Thanks for the super quick action! The first warning is now gone, but there is apparently another use of pkg_resources in postprocessing module:

.../pysteps/pysteps/postprocessing/interface.py:88: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
  import pkg_resources
/home/ritvanen/miniconda3/envs/pysteps_dev/lib/python3.13/importlib/__init__.py:129: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
  _bootstrap._exec(spec, module)

If I fix that locally, the warnings go away.
