@sonney2kblackburn, so09:59
@sonney2kthe 1,1 hack is also suboptimal09:59
blackburnsonney2k: yes because it is needed for each field10:00
@sonney2kblackburn, yeah10:00
@sonney2kand btw the problem exists for sgvector too!10:00
blackburnI do not understand why not to make it (true)10:00
@sonney2kand other referenced data10:00
blackburnby default10:00
blackburnwhat do we lose there?10:00
@sonney2kwe might just get some crashers10:00
@sonney2kbut if we do it we should do it for all SGReferencedData10:00
blackburnwhat should crash?10:01
@sonney2kblackburn, it could be that we relied on this10:01
@sonney2kdata pointer is set later10:01
@sonney2kbut that is not intended to be freed later10:01
blackburnit sounds like a hack10:02
blackburndo we really use it somewhere?10:02
@sonney2kno idea10:02
@sonney2kwe can try10:02
blackburnI do not use it anywhre10:02
@sonney2kbut the real patch would just be to remove the 'false'10:02
@sonney2kSGMatrix() : SGReferencedData()10:02
blackburnsonney2k: other option is to make serialization take care of ref counts10:02
blackburnit is kind of pain yet10:03
@sonney2kyeah but that we should do later10:03
@sonney2kwhen we do the CMap trick before serializing objects10:04
@sonney2kfor now - we can give it a try10:04
blackburnyes but no time for that now10:04
blackburnargh then we still can release10:04
@sonney2kmaybe it is more consistent anyways to have refcounting=true always10:04
blackburnyes it sounds more consistent for me10:04
@sonney2klet me just do it...10:05
blackburnfeel free, I can patch shogun only through github web now :)10:05
@sonney2kblackburn, is there an online vim on github :D10:06
@sonney2kblackburn, btw we don't have SGNDArray converted to referenced yet...10:06
blackburnnot the terrible issue10:07
@sonney2kand string / stringlist10:07
CIA-52shogun: Soeren Sonnenburg master * rbb0907c / (6 files in 2 dirs): enable reference counting by default (even in default constructors) for SG Datatypes - http://git.io/NRjBOg10:10
@sonney2kblackburn, gsomix I finally managed to get the infrastructure going for the new website10:10
@sonney2kI put it here for now http://shogun.7nn.de/10:10
@sonney2k(to not kill the old one)10:10
gsomixsonney2k, cool10:14
shogun-buildbotbuild #390 of deb2 - static_interfaces is complete: Failure [failed test libshogun]  Build details are at http://www.shogun-toolbox.org/buildbot/builders/deb2%20-%20static_interfaces/builds/390  blamelist: Soeren Sonnenburg <sonne@debian.org>10:16
@sonney2kblackburn, ^ see - some stuff seems to rely on that behavior10:19
@sonney2kanyway I guess we should rather fix the new crashes than doing it the old way...10:19
@sonney2kgsomix, can you help fixing these?10:22
gsomixsonney2k, hm, what's wrong?10:23
blackburnsonney2k: yes, lets rather fix these crashers10:25
blackburngsomix: yeah we'd appreciate if you localize it ;)10:25

blackburnsonney2k: parsebuffer should be fixed still10:47
@sonney2kblackburn, ?10:47
@sonney2k    SG_FREE(m_train_labels.vector);10:48
@sonney2kblackburn, any idea why we even copy the train labels?10:50
@sonney2kahh we need it to classify later10:50
blackburnsonney2k: to subtract min label10:51
blackburnpretty idiot thing actually10:51

CIA-52shogun: Soeren Sonnenburg master * r2535f44 / src/shogun/multiclass/KNN.cpp : remove free() in destructor (causing a double free) - http://git.io/ybQ7Lg10:56
@sonney2kblackburn, what did you mean 'parsebuffer should be fixed still?'10:57
blackburnsonney2k: it handles vectors in pretty crappy way10:58
@sonney2kblackburn, I really think you should file all the findings we just had as github issues10:59
@sonney2kotherwise this is just forgotten10:59
blackburnsonney2k: I asked gsomix to fix that :)10:59
blackburnwhat else is to do?10:59
@sonney2kblackburn, sparse stuff still fails - but I don't get it. do you have an idea?10:59

blackburnsonney2k: yes11:03
@sonney2kblackburn, ?11:03
@sonney2kcare to share?11:03
blackburnwe need to inc ref counter initially11:03
blackburnit should be 2 on creation11:03
@sonney2k    SGSparseMatrix<ST> sm=SGSparseMatrix<ST>(NULL, 0, 0, false);11:06
@sonney2kso that is the fix right?11:06
blackburnactually yes11:06
blackburncould be the fix as well11:06
@sonney2kblackburn, the other would require that we use SGSparseMatrix for SparseFeatures (to be put on todo)11:07
blackburnyes, but refcounter = 2 initially would work as well11:07
blackburnhowever it is a crappy solution :)11:07

n4nd0hi blackburn16:07
n4nd0have you heard about something called categorical prediction?16:07
n4nd0I'm reading a book about large margin methods for ASR and they present this16:08
n4nd0at first, I thought that it was going to be structured prediction16:08
n4nd0but I am reading the chapter were categorical prediction is introduced and I don't understand a sh**16:08

@sonney2kblackburn, yes - no eigen in .h18:37
@sonney2kblackburn, but usually that is not a problem (you can move any function code to -> .cpp)18:37
@sonney2kblackburn, btw same thing holds for pthreads etc18:37
@sonney2kblackburn, can you fix the memory leaks in the libshogun examples? there are quite many...18:38
@sonney2kwiking, any thoughts on getting proper gtest/gmock detection?18:39

blackburn1sonney2k: yeah thanks19:17
blackburn1sonney2k: about eigen - it is the issue with puffin's code  so it blocks us to release just now19:19

blackburn666n4nd0: exactly21:23
n4nd0blackburn666: let me ask you21:23
n4nd0I think something has gotten broken kind of badly in my computer21:24
n4nd0whenever I want to execute an example of libshogun I get21:24
n4nd0Segmentation fault (core dumped)21:24
n4nd0have you seen that before?21:24
blackburn666hmm not really21:25
blackburn666just any example fails?21:26
n4nd0I think that basically all21:26
n4nd0I just tried with basic_minimal21:26
n4nd0I am gooing to configure and compile from zero21:26
blackburn666I'd suggest to reinstall from the blank21:27
n4nd0do you mean ./configure, make clean, make and make install?21:28
n4nd0or something else?21:28
blackburn666yeah or even git clean -dfx if you have nothing unstaged for commit21:28
