[Python-modules-team] Bug#904944: joblib/0.12.1-1 appears to break dask.distributed/1.21.8+ds.1-1 autopkgtest: __init__() missing 1 required positional argument: 'pickle_cache'

[Paul Gevers]

Source: joblib, dask.distributed
Version: joblib/0.12.1-1
Version: dask.distributed/1.21.8+ds.1-1
X-Debbugs-CC: debian-ci at lists.debian.org
User: debian-ci at lists.debian.org
Usertags: breaks needs-update

Dear maintainers,

With a recent upload of joblib the autopkgtest of dask.distributed
started to fail in testing. I copied the error below. The regression
isn't visible in unstable history on ci.debian.net as there is the
python3.7 transition going on and the failure of dask.distributed was
only fixed recently and not recorded.

Currently this regression is delaying the migration of joblib to
testing by 10 days. Could you please investigate the situation and
determine which package needs to fix something, and reassign and set
severity appropriately?

More information about this bug and the reason for filing it can be
found on
