1.21.5: tests failures on some Debian architectures #20635
Description
Hello,
i've just uploaded numpy/1.21.5 and the test suite produced some failures on a few architectures we support. Please note you're going to find 2 sets of test results, because we're building for both Python 3.9.9 and Python 3.10.1.

Hmmm, quick scan, most failures seem to be related to floating point errors and I am not sure how much trouble we should go to try and get those right...
This one worries me a bit more:
It happens in the line:
But I wonder if it is something weird to do with
-NaNbeing incorrectly handles as well? I would guess at vectorization, but I doubt that makes sense for mipsel or armel.charris commentedon Dec 21, 2021
Armel doesn't have an FPU, correct? Are the instructions trapped and emulated, or is it library based? I'm trying to see how much can be attributed to the library (if used) and the reporting of exceptions (if available).

i must admit i'm not really knowledgable on all the specs and quirks of these "uncommon" archs. there's a main debian archs list here which contains references to each of them, here's the one for armel

FYI (cross-reference): The i386 failure of
test_paretolooks like the same issue as #18387sandrotosi commentedon Mar 19, 2024
