@sonney2khey gsomix22:29
gsomixsonney2k, hey22:29
@sonney2kwhat are you working on?22:29
gsomixprotocols for custom kernel22:30
gsomixsonney2k, btw, I need to fix  typemap22:31
gsomix'in' typemap for SGVector22:31
@sonney2kgsomix, wrt what?22:31
@sonney2kwhat's wrong?22:31
blackburndoes anybody remember by heart if dynamic object array should be ->reserve() before setting?22:32
@sonney2k???22:32
@sonney2kreserve?22:32
blackburnyeah or sth like tha22:32
blackburnahhhh we have a check in set_machine22:32
@sonney2kit grows autmagically22:32
blackburnyeah but it doesn't work like set(0) set(1)22:33
blackburnbut push back should be used22:33
gsomixsonney2k, for directors. it's needed, because sometimes args in methods is actually SGVector's not numpy.arrays.22:33
@sonney2kgsomix, I still don't understand - you are talking about directorin typemaps?22:33
gsomixnope, about 'in'22:34
gsomixhm, what about directorin?22:34
@sonney2kgsomix, what do you want to 'fix' in in typemaps?22:34
gsomixI want to add case where the arg is SGVector.22:35
gsomixat now only numpy.arrays may be processed22:36
@sonney2kahh - what do you want to do when arg is SGVector? shouldn't that work already?22:36
gsomixif arg is SGVector => do nothing. :)22:37
gsomixbecause this is actually SGVector22:38
@sonney2kgsomix, but swig should have wrapped SGVector already - so one should be able to pass SGVectors to functions22:38
@sonney2kgsomix, I think what is missing is some SGVector constructor that takes an SGVector as input - such that one can create an SGVector via a numpy array22:43
gsomixsonney2k, awwww, it seems that I'm stupid and there is no problem.22:45
@sonney2kgsomix, will you bring the director examples back?22:46
gsomixyep22:47
@sonney2kgsomix, so except for typemaps for model selection - what is missing now?22:50
blackburnsonney2k: can't we avoid typemaps for modelselection but extend class for that?22:51
@sonney2kblackburn, I don't understand?22:51
@sonney2kwhat do you want to extend?22:51
gsomixsonney2k, protocols for custom kernel and examples.22:51
blackburnsonney2k: add python native constructor with all {'C' : ...} stuff22:51
@sonney2kblackburn, no - that is what typemaps are for22:52
@sonney2kgsomix, ok then do these first maybe we can still manage to do these modsel typemaps before 2.0 - but lets see22:52
gsomixok22:53
blackburnsonney2k: I think handling that in C++ is a wrong way22:59
blackburnwhat I suggest is a faster in means of development way to do the same22:59
@sonney2kblackburn, please explain more...23:06
blackburnsonney2k: that {} map thing you were thinking of works only for python, right?23:06
blackburn{'C' : {1,2,3} } or os?23:07
blackburnso?23:07
@sonney2kfor any language that supports stuff like this...23:07
@sonney2kbut lets say only python - so now what?23:08
blackburnthis can be handled in python effectively23:08
blackburnso it should be python native extension, like extended constructor23:08
blackburnI see no reason to get hands dirty with that kind of parsing23:09
blackburnthis structure can be effectively parsed in python - just creating model selection parameters and setting childs23:10
blackburnany C++ version will do the same with same performance but much harder to develop, debug and maintain23:10
@sonney2kblackburn, except one thing: you cannot directly pass this dictionary to the modsel routines23:14
@sonney2kyou would have to call some function to get the C++ object23:14
blackburnIIRC everything this dictionary does can be done in python23:14
blackburnam I wrong?23:14
@sonney2kblackburn, the model selection itself runs in C++ in shogun - so you need to pass this 'modsel' object to libshogun23:15
@sonney2kso what you can do is create this object via python code23:15
@sonney2kbut you cannot have the mapping dictionary -> 'modsel' object23:16
@sonney2kthat is only possible via typemaps23:16
blackburnsonney2k: how should that dictionary look like?23:16
@sonney2kgsomix, could you please forward blackburn my email with the syntax23:17
blackburnwhat I suggest is23:17
blackburnModelSelectionParameters({'C': [0.1,0.2,0.3],'width': [1.0,5.0]})23:18
blackburnsth like that23:18
blackburnthis can be done in python natively23:19
@sonney2ksure that would work23:19
@sonney2kbut you could avoid the modelsectionparameters23:19
@sonney2kif this is done as typemap23:19
blackburnhow?23:19
@sonney2kblackburn, the same way we can pass numpy arrays...23:20
gsomixsonney2k, I cannot find this letter. O_o bad23:20
blackburnpass to modelselection?23:20
@sonney2kparse the python object - going through the dictionary/lists is not that much effort23:21
blackburnwell it is up to you :)23:21
@sonney2kforwarded23:22
gsomixsonney2k, thanks!23:23
blackburnsonney2k: can't that be done via modelselectionparameters(the-dictionary)?23:25
@sonney2kblackburn, sure but it can be done w/o the modelselectionparameters(the-dictionary) - just the-dictionary23:26
blackburnI like the thing I suggested because it is like 1 md while typemapping can take a while23:27
@sonney2kblackburn, as I said parsing dictionary / list is not so much the issue .. much more creating the object23:28
blackburnok23:28
blackburnsonney2k: we have an issue with eigen3 thing - one puffin444's class header uses it23:31
@sonney2kblackburn, hmmh can he avoid that?23:31
blackburnI asked him he will do that23:31
blackburnthanks to eigen authors we can easily map our matrices to eigen matrices23:32
@sonney2kyeah that sounds good23:33
blackburnsonney2k: do you know how can we use -isystem instead of -I?23:34
@sonney2kblackburn, what does this mean?23:34
@sonney2k-isystem???23:34
blackburnI mean we use pkg-config23:34
blackburn-isystem is just -I but w/o warnings23:34
@sonney2kblackburn, you mean the include path?23:34
blackburnyes23:34
blackburnwe use pkg-config and it produces -I23:35
@sonney2kblackburn, then simple sed magic - but do we want that?23:35
blackburnyeah warnings are confusing23:35
blackburnno idea if they will disappear at some point23:35
@sonney2kblackburn, so the assumption would be - eigen3 warnings are useless and what they did is ok right?23:36
blackburnyes sure, we trust it23:36
@sonney2kgsomix, once you are done with the stuff you have on you todo - could you please try out parsing the dicts - I mean just to get an idea how difficult this is (w/o doing anything in shogun)23:37
gsomixok23:37
blackburnsonney2k: can we unify preprocessors to support sparse somehow?23:50
@sonney2kblackburn, I don't think so ... even substracting mean will turn a sparse solution into a non-sparse one23:58
@sonney2kmaybe for sparsity preserving operations?23:58
blackburnsonney2k: hmm23:59
