I wouldn't give up so fast :-) If we'd make warning message more instructive and point people to a simple command they could run to suppress the warning that should take away a lot of the pain. Sketching here: """ DeprecationWarning: The package x.y.z is using a deprecated feature tadada at module.py:34. If you get a change, please report this to the maintainers. In order to suppress warnings for this package, please run: python3 -m warnings.ignore('::DeprecationWarning:package') """ The ignore() function would then add a warning filter to pyvenv.cfg, if available, or output instructions on how to setup the environment via the a usercustomize.py, sitecustomize.py or PYTHONWARNINGS env var. If you want a click-for-help approach, we could also put a URL into the message, which then points to a page with specific instructions (rendered to be specific to the warning instance via a Django view for example). -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Apr 21 2021) >>> Python Projects, Coaching and Support ... https://www.egenix.com/ >>> Python Product Development ... https://consulting.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
