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
