policecarhey hey, i'm manually installing shogun 1.0.0 on snowleopard and trying to make it work with a macports installed python2.6. do you happen to know where i need to put the shogun binaries for this python to be able to see the module? basically i'm looking for a macport not fink path version of /usr/local/lib/python2.6/dist-packages/ ...10:33

sonne|workpolicecar: please try shogun from git11:52
sonne|workor did it compile OK already11:52
sonne|work(I did a lot of fixes recently)11:53
policecarit compiled just fine. but thanks for the hint.11:53
sonne|workok then11:53
sonne|workjust search for e.g. modshogun.py11:53
policecari just solved the problem by adding /usr/local/lib/python2.6/dist-packages to the pythonpath a moment ago11:53
policecarwhich is not nice but it works for now11:53
sonne|workexactly what you should be doing :)11:53
policecarmaybe i missed the instruction11:53
policecarthanks for getting back to me!11:54
sonne|workpolicecar: well no - in principle it should work out of the box but everyone is cooking his own soup11:54

blackburnsonney2k: so is GLPK the only way to make MKL regression work?20:03
CIA-37shogun: Soeren Sonnenburg master * rbd6dcde / (5 files in 3 dirs):20:07
CIA-37shogun: get ruby back to work20:07
CIA-37shogun: - add configure option --ruby to be able to specify the ruby version to be used20:07
CIA-37shogun: - use rb_cObject instead of ruby_class to fix undefined symbol error20:07
CIA-37shogun: - beautify example - http://git.io/5PAJog20:07
@sonney2kblackburn, no - we have mkl_regression_3sine_waves.m for example20:08
@sonney2kso it works with regression too20:08
blackburnsonney2k: what is the problem then?20:08
@sonney2kI need to reboot again to check if things work under osx20:08
@sonney2kcu20:08
blackburnok20:08
@sonney2kblackburn, yes works all nice now20:19
@sonney2k:D20:19
blackburnsonney2k: ruby?20:20
@sonney2kyes20:20
blackburnnice20:20
@sonney2kreally weird hack I am using...20:22
@sonney2kwe no longer link to narray.so20:22
@sonney2kbut instead open it with dlopen20:22
@sonney2kand then extract the few needed functions20:22
@sonney2kwith dlsym20:22
@sonney2kregarding mkl + regression I suspect kernels are not properly normalized20:22
blackburnsonney2k: similar to java I would say?20:23
blackburnsonney2k: have you seen tikz? completely crazy stuff http://www.texample.net/tikz/examples/seismic-focal-mechanism-in-3d-view/20:24
@sonney2kone potential fix would be to use the sqrtdiag kernel normalizer20:25
@sonney2klatex wizardry...20:26
blackburnsonney2k: the problem I have now is after changing script there is an index error..20:27
blackburni.e. before train one kernel is used20:28
@sonney2kI am not sure what you are saying20:28
blackburnsonney2k: mkl is trained with one combined kernel20:28
blackburnthen another is set20:28
@sonney2kyes20:28
blackburnand apply is called20:28
@sonney2kyes20:28
blackburnand I receive index errors20:28
blackburnin apply20:28
@sonney2kin the example I pushed?20:28
blackburnno20:28
@sonney2kin which?20:29
blackburnin the example I sent to you with dropbox20:29
blackburnif you have time please take a look20:29
blackburnhmm20:30
blackburnthen if I change this line:20:30
blackburncols,rows = numpy.meshgrid(test_idxs2,train_idxs2)20:30
blackburnit segfaults..20:30
@sonney2kwhich line?20:30
@sonney2kwhich file20:31
blackburnmkl_regression_cv.py20:31
blackburn7720:31
@sonney2kdamn complex example20:32
blackburnsonney2k: sorry, it is a port of example madeleine uses20:32
blackburnin java it was even worse20:32
blackburnsonney2k: I rewrote whole example trying to solve her issue20:33
blackburnand it leaded to another issues..20:33
@sonney2kGLPK can only be used with mkl_norm=120:33
@sonney2kgreat20:33
@sonney2kI guess this is kind of spaghetti research code20:33
blackburnsonney2k: it is CV in fact20:34
@sonney2kblackburn, why are you using meshgrid20:34
blackburnsonney2k: what to use?20:34
@sonney2kjust index oeprations20:34
@sonney2koperations20:35
blackburnehmm won't it be diags?20:35
@sonney2klike m[idx][:,idx] ?20:35
shogun-buildbotbuild #235 of ruby_modular is complete: Success [build successful]  Build details are at http://www.shogun-toolbox.org/buildbot/builders/ruby_modular/builds/23520:36
blackburnsonney2k: is it a share file? did you file changed anyhow?20:36
blackburnyour*20:36
@sonney2ksry but I don't have time now - just ask I will answer late20:37
@sonney2kare20:37
blackburnsonney2k: ok sure20:38
@sonney2kblackburn, any news?23:49
blackburnsonney2k: no, I'm still pretty busy with my semester work :(23:52
blackburnsonney2k: ah yes, I've got with segfault labels23:53
blackburnwith this example23:53

@sonney2kimpressive that you always find sth new...23:56
@sonney2kno way to do anything about it w/o seeing line 417723:56
blackburnsonney2k: I guess it is free flag issue23:57
