That's really odd.
scikit-learn 0.17 should definitely work with numpy 1.10.
This looks more like a linker failure, so it being version dependent in
numpy seems strange..

folks, just to follow up on this in case anyone else runs into the
same problem: after much mucking around, i conclude that the issue is
due to a change that has taken place in numpy between versions
numpy-1.9 and numpy-1.10. in my experience, scikit-learn-0.17 cannot
be successfully built against numpy-1.10; neither can versions 0.16,
0.15 nor 0.14 for that matter.
therefore, the solution for me was to use numpy-1.9.2 instead of
numpy-1.10.2; once this change was made, not only could
scikit-learn-0.17 be built but the described unittest issues
disappeared and "nosetests sklearn --exe" was able to run completely
and successfully.
i'm not sure what this means for numpy & scikit-learn going forward in
terms of what/where a fix is needed; but hopefully for the moment,
others can be saved the trouble of facing the same struggle that i did
last week. sincerest thanks to those who took the trouble to help me
sort it out...
best regards- joe

issues...
greetings. i'm trying to build scikit-learn-0.17 into a homemade
python stack on ubuntu-14.04 and having a terrible time of it. no
matter what i try, the unittests invariably fail with such messages as
these:
ERROR: Failure: ImportError
(/usr/local/python/lib/python2.7/site-packages/sklearn/metrics/pairwise_fast.so:
undefined symbol: ATL_dasum)
ERROR: Failure: ImportError
(/usr/local/python/lib/python2.7/site-packages/sklearn/metrics/pairwise_fast.so:
undefined symbol:
ATL_dcopy)
ERROR: Failure: ImportError
(/usr/local/python/lib/python2.7/site-packages/sklearn/metrics/pairwise_fast.so:
undefined symbol:
ATL_dscal))
i have a custom built atlas3.10.0/lapack-3.4.2 against which i've
successfully built gobs of other software; i also have the ubuntu
packages libatlas-base-dev, libatlas-dev, etc, on hand and "ar -t"
tells me that the objects in question are present in both.
i'm using python-2.7.11, numpy-1.10.2 and scipy-0.16.1, all of which
build without problems and pass all unittests as expected.
at this point i'm totally stumped and would so gratefully appreciate
any advice anyone could offer. warm thanks in advance and happy
holidays to all. -joe
