bb_hi besser82 how have you been15:58
besser82bb_:  fine thanks!  And yourself?15:58
bb_doing well... how was your new year15:58
bb_i got the latest shogun from the git and the python examples give a segmentation fault16:06
bb_besser82 do you have any idea on this16:07
besser82bb_:  idea on what?16:07
bb_about the seg fault16:07
besser82bb_:  on which os?16:07
besser82bb_:  my new year started fine, btw;  how bout yours?16:08
besser82bb_:  sry, didn't read the backlog....16:08
bb_besser82 osx .. previusly it was working fine16:08
bb_besser82 but i wanted to get the latest one and now i get this problem16:09
besser82bb_:  on stuff related to osx, I actually have no ideas...  can you please run the example using valgrind?16:09
bb_besser82 i am not able to run any of the examples in python_modular16:09
bb_besser82 i deleted the older version of shogun may be i should go back to that16:10
besser82bb_:  then try to run `valgrind --track-origins  python $`, plz and paste me it's output somewhere16:11
besser82bb_:  maybe that can give me some conclusion....16:11
besser82bb_:  you may have to install valgrind first using "brew"16:12
bb_besser82 sure let me get valgrind and then try it doing it now16:12
besser82bb_:  thanks!  that might give me some sure hints whats going wrong for u16:13
bb_besser82 is there any other program similar to valgrind i can use .. valgrind is not supported for osx 10.9 they support only till 10.816:19
besser82bb_:  there might be gdb, but that is quite harder to use...16:19
besser82bb_:  maybe OSX itself ships sth like valgrind, i dunno...16:20
besser82bb_:  maybe wiking knows....16:21
besser82wiking:  ^^^ ping?16:21
bb_besser82 but what has changed from last time that it is seg faulting... i had a relatively new version16:22
bb_besser82 of shogun which i was happy with ...16:22
besser82bb_:  I dunno... maybe you compiled against the wrong python-libs?!?16:22
besser82bb_:  which would cause the segfaults when using a different py-interp...16:23
@wikingbesser82: pong16:23
besser82wiking:  is there sth. like "valgrind" for OSX 10.9?16:23
@wikingbesser82: dtrace16:23
@wikingbesser82: what's the problem16:23
besser82wiking:  bb_ has problems with segfaulting python_modular  :(16:23
@wikingbb_: can u send the output of your cmake somewhere?16:24
bb_wiking i am getting segfault after everyting compiles in the latest shogun16:24
@wikingbb_: when trying to use the interface or when compiling?16:24
besser82bb_:  does the libshogun it self segfault? did you try that?16:24
@wikingbesser82: for segfault it's better to use gdb/lldb16:24
besser82wiking:  yes, but that is quite harder for someone without debug-expirience...16:25
@wikingbb_: i suppose the interpreter and lib does not match. u have macports right?16:25
besser82wiking:  valgrind atleast gives some useful hints what's wrong in a quite simple way ;)16:25
bb_wiking yes i have macports .. when i am trying to run the the example in pythong modular16:25
@wikingbb_: i think what's happening maybe is that cmake detects your system's python but it tries to use the macports' python lib. or the other way around. i had those segfaults in this scenario16:26
@wikingbb_: plz try to pastebin the output of your cmake16:26
@wikingalthough i must say that i haven't tried to compile/use python modular lately on osx16:27
@wikingso maaaaaybe there's another reason16:27
@wikingthis is my first guess16:27
bb_wiking here is the output for cmake
bb_wiking it was working fine all these days with the older version of shogun and i decided to get the lastest one16:29
@wikingmmm seems it's using system's python16:29
bb_wiking yes it was doing the same when it was working perfectly16:30
@wikingbb_: do u use system's python interpreter or macports for running the example16:30
@wikingi.e. what's the output of this: port select python16:31
bb_wiking systems python interpreter16:31
@wikingthen i guess we have a bug16:31
bb_| => port select python Available versions for python: none (active) python25-apple python26-apple python27 python27-apple16:32
@wikinglooking at
@wikingdoes not surprise me16:32
@wikingbtw what is the example u try to run?16:33 in graphical in undocumented python modular16:33
bb_wiking how can we work around this16:35
bb_wiking should i just revert back to the old one.. is there a way to get old version from git16:38
@wikingbb_: yes16:38
@wikinggit checkout <commit version that worked for you>16:38
bb_wiking there is no way for me to know that..16:39
@wikinglife is cruel16:42
@wikingoh man it's just a pain to see this shit protobuf cmake16:55
bb_wiking i am stuck here not sure which shogun i had earlier..17:14
bb_wiking let me know if you can think of a workaround or need something from with dtrace or will try to install valgrind17:15

@iglesiasghey guys17:47
@iglesiasgabout the Google docs17:47
@iglesiasgdo you happen to know who Christian Dersch is?17:48
@iglesiasgI got a mail asking for permission to join the doc17:48
besser82iglesiasg:  yes, he is one me buddies18:35
@iglesiasgbesser82, all right, I will add him as a viewer18:35
besser82iglesiasg:  BSc astro-physics, currently doing MSc18:35
besser82iglesiasg:  just did so  ;)18:35
besser82iglesiasg:  He possibly wants to mentor sth. like openCV intergration or that Markov stuffs18:36
besser82iglesiasg:  thanks for asking!  :D18:37
@iglesiasgno problem at all :)18:37

pickle27sonney2k: looking at the website now, I see what you mean about the db, anyway you could dump the production database into sqlite3 and send me the file?22:35
pickle27or how do you usually work on the site? just live...?22:35
-!- thoralf [] has quit [Ping timeout: 260 seconds]22:47
@sonney2kpickle27, no that is the problem - I can dump the mysql db but no idea how to get that into sqlite format22:54
@sonney2kpickle27, btw want to mentor this year?22:54

pickle27sonney2k: I would love too!23:15
pickle27hmm can you send me the mysql dump? I'll try and figure it out23:15
@sonney2kpickle27, what would you want to mentor?23:17
@sonney2kpickle27, opencv integration?23:17
pickle27sure I could do that although I don't know if that scope is big enough for GSOC23:18
pickle27maybe integration plus some awesome examples23:18
@sonney2kpickle27, yes sounds cool23:19
@sonney2kpickle27, what is your google mail addr?23:19
@sonney2kI give you write acces to the doc23:20
pickle27sorry which doc?23:23
@sonney2kpickle27, ok sent you the dump23:29
@sonney2kpickle27, if you figure sth out would be nice23:29
pickle27sonney2k: okay I'll see what I can with it23:29
@sonney2kpickle27, and please add your idea / yourself as mentors in the google doc23:29
pickle27I will!23:29
pickle27also how tied are we to django for the site?23:30
pickle27flask might be simpler23:30
pickle27I'll probably stick with django but just thought I'd see what you thought23:30
@sonney2kpickle27, lets just stick with django23:32
pickle27sounds good23:33
@sonney2kpickle27, in principle we don't need the extensive stuff we have now in django but that is the way it is and at least people can admin the website w/o editing the code23:38
pickle27sonney2k: look what I found:
pickle27seems to work23:41
@sonney2kpickle27, *lol*23:42
@sonney2kpickle27, but cool!23:42
@sonney2kpickle27, just make sure you never expose the real db with user names etc in some PR or so23:42
pickle27good point23:44
@sonney2kpickle27, the convert almost works...23:49
@sonney2kpickle27, I have some weird \r in the output23:49
-!- new_lido [~walid@] has quit [Quit: Leaving]23:51
pickle27seemed to work for me23:51
pickle27when I load the shogun page I get all the tabs and stuff now23:51
pickle27which is really all I needed23:51
pickle27ah I see what you mean23:54
pickle27I'll try and fix the script23:55
@sonney2kpickle27, keep me posted - it is still much better with this script than w/o anything :D23:57
pickle27yeah this way you can play around locally at least23:58
