Bug#1064280: scikit-learn: armhf tests failing: not giving expected divide-by-zero warning

[Drew Parsons]

Source: scikit-learn
Version: 1.4.1.post1+dfsg-1
Severity: normal

sklearn 1.4 is passing most tests but two remain "failing" on armhf.

test_tfidf_no_smoothing and test_qda_regularization are "expected to
fail" by emitting a divide-by-zero warning, but they emit no such
exception.

I guess it's a particularity of the way armhf handles floating point
calculations.  I'd suggest just skipping these two tests on armhf,
unless upstream wants to inspect more deeply to fix it.

armhf was already failing tests so this will not prevent migration to
testing (i.e. no need for severity: serious).
