sanujlisitsyn, ping09:37
lisitsynsanuj: hey09:40
sanujthis is fine right?09:40
sanujhttps://github.com/sanuj/swig-tutorial/tree/master/tutorial-309:40
sanujmy toy swig interfaces for template09:41
lisitsynsanuj: yeah looks ok09:41
lisitsynsanuj: there is no python example though09:41
lisitsyndid you manage to make it work?09:42
sanujyeah09:42
sanujbuild it setup.py09:42
sanujimport square09:42
sanujsq = square.SquareInt(5)09:42
sanujsq.area()09:42
sanuj= 2509:42
sanuj:P09:42
sanujall this is working09:42
lisitsynok cool09:43
lisitsynnow should be easy to make tag thing work :)09:43
sanujyes i'll move on to that now09:43
sanujthis turned out to be easier than i thought09:43
sanuj:)09:43

sanujlisitsyn, still there?09:59
lisitsynsanuj: yes09:59
sanujin my prototype10:00
sanuji'm using tags to get instead of string10:00
sanujwe had discussed this earlier i guess10:00
sanujhttps://github.com/sanuj/shogun-plugin-arch/blob/master/tags-string/src/shogun/SGObject.hpp10:01
sanujcan't we infer the type from the argument tag instead of casting it10:02
sanujlisitsyn, ^10:04
lisitsynsanuj: yes it should work ok with tags10:04
sanujokay10:05
lisitsynsanuj: you just have to 'instantiate' these gets10:05
lisitsynfor specific types like int, double10:05
lisitsynbut as they have different argument types10:05
lisitsynit should work10:05
sanujalright, i'll try10:05

@HeikoSyes13:51
lisitsynmake shogun grate again13:52
lisitsyn:D13:52
sanujlisitsyn, getting that include error13:52
lisitsynah sorry13:52
sanujlisitsyn, look up ^^13:53
lisitsynwell it looks like the path is wrong :)13:53
sanujcmake is able to build it without swig13:53
lisitsynsrc/shogun/Tag.hpp13:53
sanujlisitsyn, i'll share the code on github13:53
lisitsynI don't think src should be there13:53
sanujlisitsyn, i called python setup.py from a folder which has src13:54
lisitsynwhy do you use setup.py?13:54
sanujswig docs13:54
lisitsynI mean in shogun we already build it with cmake13:55
lisitsynwhy other approach?13:55
sanujjust for testing13:55
sanujswig docs suggested setup.py so i used it to build my toy examples13:56
sanuji'll try to build it with cmake13:56
lisitsynsanuj: ok just show me what's changed or errors you ge13:56

sanujwith some problems15:18
@wikinganything i can help with15:19
@wikingmeaning with the problems/15:19
@wiking?15:19
sanuji'll share the code first15:19

@wikingsanuj: for(std::unordered_map<std::string, Any*>::iterator it = tag_map.begin(); it != tag_map.end(); ++it)15:24
@wikingfor_each? :)15:24
sanujobj.set(....) doesn't work15:25
@wikingit's much shorter15:25
@wikingis this from python interface?15:25
@wikingi suppose, right?15:25
@wikingok lemme pull15:25
sanujsure i'll do that15:25
@wikingand try to compile15:25
sanujyes it's from python interface15:26
@wikingok the cmake files will need some love15:26
@wikingbut lemme try it on linu15:27
@wiking*linux15:27
sanujhaha15:27
sanuji don't know much cmake15:27
@wikingdont worry we'll fix it15:27
sanujmake build dir in tags-string15:27
@wikingyeah15:29
@wikingtrying that15:29
@wikingthe problem is15:29
@wikingImportError: dynamic module does not define init function (init_shogun)15:29
sanujimport shogun worked for me15:30
sanujin python15:30
@wikingah i think i have a problem with having another version15:30
@wikingof shogun in the path15:30
sanujgo in tags-string/build/src/interfaces and then import15:31
sanujyou will have to do something about the path15:31
@wikingyep yep15:31
@wikingi know15:31
@wikingi'm just saying15:31
sanuj:D15:31
@wikingthat i have another version of shogun in the path15:31
sanuji know you know15:31
@wikinghence the meixup15:31

@wikingmmm15:32
lisitsynwhy15:32

@wikingit doesn't find that 'set'15:34
lisitsynyes but why?15:34
@wikinghow's tag added to SGObject15:34
@wiking?15:34
lisitsynwhich repo15:34
@wikingah wait15:34
@wikingi've fucked up the thing15:35
@wikingsanuj: should it be15:35
sanujthe following perfectly in c++15:35
sanujSGObject obj;15:35
sanujTag<int> length_tag("side");15:35
sanujobj.set(length_tag, 10);15:35
@wikingsanuj: how did you create Tag<int> in python15:36
sanuj%template(TagInt) Tag<int>;15:36
@wikingTagInt15:36
@wikingok15:36
sanujoh i think why15:39
sanujbecause15:39
sanujtemplate <typename T>15:39
sanuj    void set(Tag<T> tag, T value);15:39
sanujit's a template method which are treated differently in swig15:39
lisitsynyes you have to instantiate15:39
lisitsynset<T>15:39
lisitsynfor some types15:39
sanujwill do it now15:40
sanujsorry for the trouble wiking15:40

sanujeverything is working now15:55

sanujlength_tag = TagInt("side")15:56
sanujobj.setInt(length_tag, 10)15:56
sanuja = obj.getInt(length_tag)15:56
sanuja is <Swig Object of type 'int *' at 0x7f7c00f13de0>15:56
sanujso 3 + obj.getInt(length_tag) won't work15:57
sanujthis is because15:57
sanujtemplate <typename T>15:57
sanujT& get(Tag<T> tag);15:57
sanujmore specifically15:57

lisitsynhmm yeah15:58
lisitsynsomehow it returned a wrapper for int*15:58
lisitsynnot the value itself15:58
sanujyeah15:58
sanujwhy do we have T&15:58
sanujI tried T but gives error15:58
sanujwith swig15:59
lisitsynsanuj: ok I get the problem16:00
lisitsynnot that I know the reason though16:00
lisitsynsanuj: could you please check it in swig docs?16:00
lisitsynhow to map primitive types and so on16:00
sanujokay16:00
sanujlisitsyn, T& is because of any16:01
sanujbut i don't know why we have T& there16:01
lisitsynnah that's ok16:01
lisitsynwhy not?16:01
lisitsynsanuj: oh16:01
lisitsynwhta happens if you try T then?16:02

Saurabh7HeikoS: Hey I was trying things with subsets and thread safety16:56
@HeikoSSaurabh7: cool!16:56
@HeikoSand?16:56
Saurabh7To do that i thought of one way i put it in the doc16:57
Saurabh7we would have to pass an identifier to the index_conversion method16:58
Saurabh7because thats what is being used everywhere to access16:58
Saurabh7but we dont have control when the index conversion happens in alogs16:58
Saurabh7so I think we would have to update feature access methods , kernel compute things and labels for that16:59
Saurabh7if to be done this way16:59
