actually time_series ones aren't BE specific since happen also on armel: https://buildd.debian.org/status/fetch.php?pkg=pandas&arch=armel&ver=0.17.0%2Bgit8-gcac4ad2-1&stamp=1444493597

pls pd.show_versions() on the platforms where its failing. These have been testing on myriad linux/mac/windows both 32/64, so not sure what the issue would be.

once again -- those failures are architecture specific -- pass fine on conventional x86 (32 or 64 bit). Those full reports above always contain the printout of show_versions like this one on armel:

python2.7 ci/print_versions.py; \
    cd build/; LC_ALL=C.UTF-8 xvfb-run -a -s "-screen 0 1280x1024x24 -noreset" \
      python2.7 /usr/bin/nosetests -s -v -A 'not network and not disabled' --exclude 'test_(bar_log|set_locale|constructor_compound_dtypes|invalid_index_types)'  pandas;

do you have the chart of how many users actually use these platforms? would be interested to see.

if overall, not just for pandas, then see http://popcon.debian.org/ . Remember that this is voluntary submissions, actual number of users is somewhere between x10 and x100 of that ;) Also note that failures on big endian platforms are quite often not big endian specific but rather trigger bugs in the code which otherwise go not mentioned on regular little endian, e.g. that one test_msgpack('0.16.2',) could well be such since e.g. 72057594037927936 is 0x100000000000000 (thus 1 is in the wrong byte ;) ) -- either it is incorrect placement during IO or memory alignment issue is to be figured out by looking inside the code (which I haven't done yet)

nice graphs! ok so after i386/amd64 things drop off a lot.

sure thing, but e.g. more and more arms you might see around, so who knows how it will look in e.g. 10 years? ;)

some of those persisted in 0.17.1: https://buildd.debian.org/status/fetch.php?pkg=pandas&arch=s390x&ver=0.17.1-1&stamp=1449119537

love to have fixes for these. but keep in mind that we don't formally support these platforms as they are not regularly tested. so fixes would have to be specifically targeted with tests (see my comments on #12269).

@yarikoptic can you confirm whether these failures persist with up-to-date versions?

The constraint on trying to troubleshoot these architectures is that we don't have them available in the CI. I don't suppose Debian has a "Guest CI" program for exactly this situation?

While we do want to fix errors on various platforms the biggest challenge is finding a CI providers that support various architectures. Additionally, these test examples appear to have run on fairly old versions of pandas.

Due to these issues and the inactivity going to close. Happy to reopen if someone could confirm these issues persist on master
