@sonney2kblackburn1, you should really post such things to the mailinglist...21:11
blackburn1sonney2k: yes but is there anyone who can help?21:11
@sonney2keven if not it is better to have a) traffic on the list b) to have a public reference for s.o. trying to do the same c) someone posting the solution21:12

@sonney2kand fails correctly21:36
@sonney2kbut still sth is looking weird21:36
blackburn1sonney2k: what is the fucking way to get it instead of SHOGUNEXCEPTION?21:36
@sonney2kdidn't test this here with regression21:36
@sonney2knot just call init_shogun with no arguments21:36
@sonney2kbut proper string functions21:36
@sonney2kor call init_shogun_with_defaults21:36
blackburn1sonney2k: do you have dropbox?21:37
blackburn1I shared a folder21:37
@sonney2kare the matrices you create proper positive definite?21:37

@sonney2kthe example doesn't even work with CLibSVR21:44
blackburn1sonney2k: and what to do?21:44
@sonney2kno idea21:45
@sonney2kahh the SG_UNREF stuff was wrong21:46
blackburn1sonney2k: more I do shogun more I do not understand21:47
@sonney2kyou forget to SG_REF the objects you later want to still use21:47
@sonney2krule is - you need to SG_REF any object that you want to use later21:48
blackburn1why not to SG_REF on creation?21:48
@sonney2kotherwise putting the object into any shogun function will make shogun take care of it incl. destruction21:48
blackburn1sonney2k:21:48
blackburn1did21:48
blackburn1you21:48
blackburn1receive21:48
blackburn1python script21:48
