Regression tests pass but return unnecessary output (errors and warnings) #103186
Description
Just built python for the first time using the devguide and I noticed some (deprecation) warnings and errors in the regression tests, even though all the tests (that ran) passed.

Raising this issue as a base for my first pull request.
