@besser82pranet: so your problem is about that hdf5-headers, right?12:42

pranetyes12:42
@besser82pranet: don't mess with your system...12:42
pranet=(12:43
@besser82pranet: is there any mpi.h located inside /usr/include12:43
@besser82pranet: or possibly inside some subfolder?12:43
pranetthere was not, until i copied it from usr/include/openmpi to that location12:43
pranetnow the mpi.h error is gone, replaced by another (mpicxx.h)12:44
@besser82pranet: lemme try to reproduce, will setup some VM with *buntu 12.0412:44
pranetwhich is in /usr/include/openmpi/openmpi/ompi/mpi/cxx12:45
pranetis it normal to have two openmpi folders one after the other?12:45
pranetthat seems to be the problem12:45
@besser82pranet: just be patient a sec, vm is installing ;)12:46
pranetsure thing12:46
pranetthanks :D12:46
@besser82pranet: np  ;)12:46

pranetto do that i need to delete the build folder right?13:49

@besser82sonne|work: which config?15:07
@besser82Vijay05: what do you mean by "default settings"?15:08
sonne|workerr docuemtnation15:08
sonne|workdoc15:08
@besser82sonne|work: hehe, that makes more sense  ;)15:08
@besser82sonne|work: tell me howto and I can dooooooo it  :D15:08
Vijay05i mean. install all things.15:08
@besser82Vijay05: all things?15:08
@besser82Vijay05: that would be pretty much15:09
sonne|workbesser82: well git grep for some string in there - it is in shogun's src15:09
@besser82sonne|work: kk, will put that on my $joblist15:09
@besser82Vijay05: How do you want to use shogun C++, Python, Ruby??15:09
Vijay05C++ and python15:10
Vijay05matlab, python interface15:10

@besser82Vijay05: I'm not sure about matlab...15:11
@besser82Vijay05: but basically `cmake -DPythonModular=ON -DUSE_SVMLIGHT=ON -DMatlabStatic=ON ..` should do the trick  ;)15:12
Vijay05I see the option 'OPTION(MatlabStatic "Matlab Static" OFF)'  in CMakeLists.txt . So I asked15:12
@besser82Vijay05: you will need to remove && recreate the build-dir prior to changing options15:13
@besser82Vijay05: if you ran cmake then you do the usual `make -j$number_of_cpu_cores+1` and get a cup of coffee/tea  ;)15:13
Vijay05ok. What does this Matlab Static thing do?15:14
Vijay05Can we call shogun functions from matlab?15:14
@besser82Vijay05: turn on the buld of matlab interface15:14
@besser82Vijay05: with that interface, basically yes, but don't ask me which and if all is supported...15:15
Vijay05OkOKok15:16
@besser82Vijay05: if run into troubles during build, you probably want to ask wiking or sonney2k, since I don't own any products with a bitten fruit on them  ;)15:17
@besser82Vijay05: neither I have knowledge about how things are going on macs15:17
Vijay05Ok.15:18
Vijay05I will ask them if I have any prob. Thanks.15:19
@besser82Vijay05: are there still any open questions from you?  I'm asking, because otherwise I'd be afk for lunch  ;)15:19
@besser82Vijay05: you're welcome  :D15:19
Vijay05No asof now. I am trying to install.15:19

Vijay05I have now built the shogun from source but I'm not able to see any files in build folder. How do I include the path of shogun when I run from matlab/octave ?18:08
dhruv13Vijay05: I think the examples are in shogun/examples/undocumented/matlab_and_octave18:18
dhruv13Vijay05: The check.sh script runs the examples and tests whether they work on your system18:19
dhruv13Vijay05: Is that what you were looking for?18:19
Vijay05ok let me try18:19
Vijay05Dhruv: It is giving error18:22
Vijay05-n running classifier_gmnpsvm.m ..  ERROR -n running classifier_gpbtsvm.m ..  ERROR -n running classifier_knn.m ..  ERROR18:23
dhruv13Vijay05: did you give the cmake option for including the octave build interface?18:31
dhruv13Vijay05: See here for details: https://github.com/shogun-toolbox/shogun/blob/develop/doc/md/INSTALL.md18:32
Vijay05I used this cmake -DPythonModular=ON -DUSE_SVMLIGHT=ON -DMatlabStatic=ON18:32

dhruv13Vijay05: In the mean time, are these helpful? http://www.shogun-toolbox.org/doc/en/3.0.0/octave_static_examples.html18:42
dhruv13Vijay05: http://www.shogun-toolbox.org/doc/en/3.0.0/octave_modular_examples.html18:42
dhruv13i think some tests are only for octave modular?18:42
Vijay05yes. I saw these.. I tried to run these after installation. But couldnot run them. So when I checked the build folder, it was empty18:43
dhruv13that's a little weird... i'm pretty sure the build folder is not supposed to be empty18:43
Vijay05but nothing seems to be working for me. I'm trying to reinstall from the beginning18:43
dhruv13yeah18:44
dhruv13try this: http://www.shogun-toolbox.org/doc/en/latest/staticinterfaces.html#staticoctaveinterf_sec18:44
dhruv13it should help you test your interface installation18:45
Vijay05thanks man18:46
dhruv13you're welcome! :-)18:46
dhruv13i hope i helped though...18:47
Vijay05What all dependencies you installed for installing shogun?18:50
dhruv13lapack is pretty important, along with libblas18:51
dhruv13the stuff i needed to use needed those18:52
dhruv13nothing much else particularly18:52
Vijay05ok18:59
HeikoS1dhruv13: Vijay05, try to avoid the static interfaces if possible19:00
HeikoS1the modular ones are much more complete!19:00
Vijay05ok19:00
Vijay05I guess, i need to install cplex, gdb and mosex. It has dependencies on these19:01

HeikoS1stefan88: depends on #applications19:29
HeikoS1so send us one :)19:29
stefan88HeikoS1: will start working on it soon ;) I was just wondering if there is a fixed number of students you can accept19:30
@sonney2kHeikoS1, what do you think how many slots should we be requesting?19:30
HeikoS1around 8 as last year, maybe some more or less19:30
HeikoS1sonney2k: maybe 10 ? :)19:30
stefan88well if they give you at least 5 then that is still not bad19:31
@sonney2kHeikoS1, yeah around that19:31
HeikoS1sonney2k: we should get more mentors19:31
HeikoS1than we can get 12 :)19:31
stefan88And what is the competition like, were there many masters and Phds last years?19:31
stefan88in previous years * blaah19:31
@sonney2kHeikoS1, don't we have like 18 already?!19:31
HeikoS1sonney2k: we will not survive that ;)19:32
@sonney2kHeikoS1, with not every mentor having registered19:32
@sonney2kHeikoS1, well I hope you do19:32
HeikoS1stefan88: yes both, but we take students mainly based on quality of their code and more important motivation19:32
HeikoS1so undergraduate is totally fine, as is phd student19:32
HeikoS1sonney2k: give them a few days19:32
HeikoS1some came in today19:32
@sonney2kHeikoS1, with that amount it becomes hard to be sure who is who - we don't want spam mentors... lisitsyn probably remembers - we had some trying last year19:33

@iglesiasgthoralf, you may have noted that the editor is a little bit not so good :)23:00
@iglesiasgthe web one23:00
lisitsynthoralf: could you just -> your changes to github thing23:00
lisitsynyou may do this pretty simple with their editor23:00
lisitsynit would issue a PR so iglesiasg could merge then update23:01
lisitsynso you can be sure you didn't ruin anything about markup23:01
thoralfI'll try.23:02
thoralfGimme a second.23:02
thoralfiglesiasg, see my PR.23:05
thoralfDirectly editing the file on the repo and creating a PR is cool.23:06
thoralfDidn't know that.23:06

@iglesiasgthoralf, done!23:06
thoralfWhat a pain.23:06
@iglesiasgthoralf, can you update in the website as well please?23:07
thoralfHow to do this?23:07
@iglesiasgthoralf, the editor of the admin interface has one button to open the html version of the article. You basically just copy the html of the repo and paste it there23:08
@iglesiasgthoralf, but I can do it if so23:08
thoralfShould be fine now.23:08
@iglesiasgthoralf, indeed! sosvm approx looking good :)23:09
thoralfWhat a hell.23:10
thoralfWho invented this workflow?23:10
@iglesiasgthoralf, me, but willing to change it for something automatic if possible23:11
thoralflol23:11
thoralfSorry. ;)23:11
@iglesiasgI asked sonney2k about just putting the html in my repo directly in the web server but it stayed there23:11
@iglesiasgthoralf, anyway, although I agree it is very silly23:12
@iglesiasgthoralf, just copying-pasting the html in the admin interface is a matter of 10 seconds (just 2 really)23:13
@iglesiasglast year I was using the admin editor directly, that was a hell...23:13
thoralfiglesiasg: The most silly thing was to edit the webpage first instead of your repo ;)23:13
@iglesiasg:D23:14
thoralfiglesiasg: Okay, I did everything you want.  The improved version is only and I will disappear for a few days... so please send change requests to hushell (or whomever ;))23:15
thoralfNeed to sleep now, see you!23:15
@iglesiasgthoralf, good night! Thanks!23:15
dhruv13__hello! I have a quick question23:15
dhruv13__after I make a small change in a src file, i would expect make to rebuild only the affected objects23:16
dhruv13__in the build folder23:16
dhruv13__it makes the entire thing again23:16
dhruv13__how do i solve this?23:16
thoralfdhruv13__: Just type make in the build folder should do.23:16
thoralfmake libshogun or make shogun-unit-test23:17
dhruv13__did that, it's taking way too long23:17
dhruv13__oh23:17
thoralfOkay, two things:23:17
thoralf1. make -j (n+1), where n is the number of cores23:18
thoralf2. cmake to create the build folder, then make in the build folder gives you a first build.  Changing a file and just calling "make" again in the build folder should be good -- do not call cmake again.23:18
dhruv13__okay23:19
dhruv13__forgot about the cores option... sorry23:19
thoralfBye!23:19

dhruv13__thank you!23:20
@iglesiasgdhruv13__, also note that modifying a header file will cause recompilation of a bunch of things. That is not the same that if you just modify a cpp file23:21
dhruv13__iglesiasg: yeah, totally forgot about that! thanks!!23:22
dhruv13__how do i run unit tests to check my patch?23:24
dhruv13__okay, found the test folder in the src23:25
dhruv13__thanks for the help!23:26
@iglesiasgHeikoS1, around?23:26
dhruv13__iglesiasg: i am attempting to fix issue #1888, and i want to know what checks I am supposed to do before I submit a pull request23:32
dhruv13__iglesiasg: the pull request generated by pranet did not completely fix the problem23:32
@iglesiasgdhruv13__, send me the link to the issue please so you save me one minute :)23:32
