Package: sepp Version: 4.5.1+really4.5.1+dfsg-2 Severity: normal Dear Maintainer,
Starting with python 3.10, directly importing Mapping from collections does not work. python 3.10[1] deprecated aliases to Collections Abstract Base Classes from the collections module have been removed. These imports must be done from collections.abc. sepp does such an import in sepp/alignment.py, and I suggest the following simple patch: --- a/sepp/alignment.py +++ b/sepp/alignment.py @@ -26,7 +26,8 @@ import re from sepp.filemgr import open_with_intermediates -from collections import Mapping + +from collections.abc import Mapping import copy from sepp import get_logger import io I also filed an upstream bug at [2]. Cheers! 1. https://docs.python.org/3/whatsnew/3.10.html 2. https://github.com/smirarab/sepp/issues/117
