DeprecationWarning regarding use of distutils Version classes #6092
Description
What happened:
While working on some tests that catch and check for warnings in my library I found that xarray with new versions of Python (I think this is the trigger) causes a ton of DeprecationWarnings on import:
/home/davidh/miniconda3/envs/satpy_py39/lib/python3.9/site-packages/xarray/core/pycompat.py:22: DeprecationWarning: distutils Version classes are deprecated. Use packaging.version instead.
duck_array_version = LooseVersion(duck_array_module.__version__)What you expected to happen:
No warnings.
Minimal Complete Verifiable Example:
import warnings
warnings.simplefilter("always")
import xarray as xrResults in:
