@HeikoSiglesiasg: good evening08:42
@wiking:)08:49
@HeikoSwiking: heya08:49
@wikingwhere r u guys? :)08:49

@HeikoSiglesiasg, https://github.com/shogun-toolbox/shogun/wiki/SWIG-issues08:49
@wikingah ok thatswhy it's good evening08:49
@wikingit's 3pm here08:49
@wikingHeikoS: for swig issues we shoulg go with d-poiinters08:51
@HeikoSwiking: 3pm nice08:51
@HeikoSwiking: yeah we thought about that too08:51
@HeikoSwiking: what about writing some things down08:51
@HeikoSwiking: so that its not just all in our heads08:51
@HeikoSand maybe we can make some entrance tasks from this08:53
@HeikoSwiking: could you explain the d-pointer stuff a bit?08:53
@wikingmmm not now08:53
@wikingstill working here :)08:53
@wikingbut here's a good article about it08:54

@iglesiasgwhen we build PythonModular with Eigen support we get some Eigen__MatrixXt stuff in modshogunPYTHON_wrap.cxx14:06
@iglesiasgthis is not there when building w/o Eigen14:07
@wikingiglesiasg: mmm then that means that eigen is being imported in a header14:11
@wikingsomewhere...14:11
@iglesiasgwiking: I checked that with grep and didn't find it, so at least no direct include14:12
@iglesiasggrep -R eigen */*.h -- that's how I checked it14:12

@wikingthe linalg shouldn't matter14:14
@wikingat least not the internal one14:14
@wikingi reckon you can throw it out from machine/gp/SingleLaplacianInferenceMethodWithLBFGS.h14:14
@iglesiasglet me try that14:15
@wikingit's a common mistake done by Wu Lin14:15
@wikinghe always did this regardless how many times i told not to do this14:15
@wikingah now14:15
@wiking*no14:16
@wikinghe fucked it up14:16
@wiking/* compute the gradient given the current alpha*/14:16

@wikingEigen::Map<Eigen::VectorXd>* gradient);14:16

@wikingfloat64_t* psi);14:16
@iglesiasgarrrrgh14:16
@wikingthis is a private function in the header14:16
@iglesiasgthat is not nice in the header14:16
@wikingbut i reckon you can hide this14:16
@wikingmmm14:17
@wikingwell i worst case what can be done14:17
@wikingis to make this into a static function14:17
@wikingwhere u pass all the variables of the class14:17
@wikingget_psi_wrt_alpha uses some of the object variables14:17
@wikingsame goes for get_gradient_wrt_alpha14:18
@wikingok now14:18
@wikingthis should be fairly easy to fix14:19
@wikingEigen::Map<Eigen::VectorXd> eigen_alpha(alpha_cast, dim);14:19
@wikingfloat64_t psi = 0.0;14:19
@wikingobj_prt->get_psi_wrt_alpha(&eigen_alpha, &psi);14:19
@wikingEigen::Map<Eigen::VectorXd> eigen_gradient(gradient, dim);14:19
@wikingobj_prt->get_gradient_wrt_alpha(&eigen_alpha, &eigen_gradient);14:19
@wikingas these are all maps of some very standard arrays14:19
@wikingso just do the mapping within those functions :P14:19
lambdaywiking: iglesiasg: I just removed this one - mathematics/linalg/dotproduct/DenseEigen3DotProduct.h14:20
lambdaythis one is deprecated and is no longer needed14:20
@wikinglambday: commited?14:20
@wikingif so then just push it14:20
lambdaywiking: didn't push yet - still fixing some doxygen bugs14:20
lambdayalright14:20
lambdaypushing whatever I have till now14:20
@wikingand once iglesiasg fixes that then swig wont generate eigen mappings :P14:20
@iglesiasgwiking: why the linalg ones shouldn't matter though? They're just skipped by swig, I am guessing14:21
@wikingiglesiasg: because those headers are used internally in the linalg part of shgun14:21
@wikingi.e. we don't do mappings over that14:21
@wikingiglesiasg: so it's almost like d-pointers14:21
@iglesiasgallright14:22
@wikinglambday: how about mathematics/linalg/linsolver/IterativeSolverIterator.h14:22
@wiking?14:22
lambdaywiking: that one includes eigen3 in the header?14:23
@wikingbut i reckon we don't do mappings of that either or?14:23
lambdaywiking: let me check14:23
@wikingmathematics/linalg/linsolver/IterativeSolverIterator.h:#include <shogun/mathematics/eigen3.h>14:23
@wikingno we are good14:23
lambdaywiking: should be avoided... when i did that I didn't know much14:23
lambdaywill fix14:23
@wikingcool14:24
@wikingiglesiasg: although i wonder about SingleLaplacianInferenceMethodWithLBFGS as well....14:24
lambdaywiking: but iirc then iterative solver iterator is used internally14:24
lambdayI mean, its not exposed14:24
@wikingoh nothing...14:24
@wikingiglesiasg:14:24
@wikinginterfaces/modular/GaussianProcess.i:%rename(SingleLaplacianInferenceMethodWithLBFGS) CSingleLaplacianInferenceMethodWithLBFGS;14:24
@wikinginterfaces/modular/GaussianProcess.i:%include <shogun/machine/gp/SingleLaplacianInferenceMethodWithLBFGS.h>14:24
@wikinginterfaces/modular/GaussianProcess_includes.i: #include <shogun/machine/gp/SingleLaplacianInferenceMethodWithLBFGS.h>14:24
@wikingthis is why eigen is actually in the modshogun_PYTHON.cxx14:25
@wikinggit grep IterativeSolverIterator -- '*.i'14:25
@wikingis an empty set14:25
lambdaywiking: yeah that's what I thought - shouldn't matter14:25
@wikingindeed14:26
@wikingso maybe once iglesiasg fixes that shit in SingleLaplacianInferenceMethodWithLBFGS we'll have travis working again :)14:26
@wiking\o/14:26
lambdaywiking: btw about khaled's random matrix/vector patch14:31
lambdaywiking: as of now I think its better to keep it within linalg14:32
lambdaywiking: Heiko suggested something - that we maybe want to put it alongside Random.h14:32
lambdaybut this thing heavily uses viennacl and then we'll have viennacl code in many places apart from linalg14:33
lambdaywiking: btw I just noticed in some of the linalg functions khaled has kept generic implementation as Eigen3 specialization... maybe I'll change those14:33
lambdaySpecialPurpose.h.. Core.h etc14:34
lambdayiglesiasg: wiking: for eigen mapping stuff, we can use SGMatrix's map operator and Eigen constructor.. its neater14:40
@iglesiasglambday: I am following the style how Wu did it in other parts of that file and just pass the float* and the dimension around14:41
@iglesiasglambday: but I agree with you, it's better that other way14:42
lambdayiglesiasg: yeah maybe for next tasks we can.14:43
@iglesiasgin any case, this code has really weird things...14:44
@iglesiasgI don't really see the point of passing around Eigen::VectorXd* alpha and do the math operations as *alpha14:44
lambdayiglesiasg: I guess eigen3 does deep copy.. maybe use reference?14:50
@iglesiasglambday: I'd guess that it doesn't do deep copy, but I am not sure14:51
lambdayiglesiasg: let me check14:51
@wikingmap is not a deep copy14:51
@wikingjust a wrapping14:51
@iglesiasglambday: anyhow, since I am passing the float* together with the dimension, I don't need to be aware of that just yet14:51
lambdayiglesiasg: I remember khaled saying this once14:51
lambdaynah map is not14:52
@iglesiasgis not deep copy?14:52
lambdaymap is not deep copy..14:52
@wikingEigen::Map<Eigen::VectorXd>14:52
@iglesiasgright14:52
@wikingit's a simple wrapping14:52
@wikingnothing else14:52
lambdaybut VectorXd vec1 = vec2 does deep copy14:52
@iglesiasgI hope this SingleLaplacianInferenceMethodWithLBFGS is unit tested14:53
@iglesiasgotherwise this refactoring might end up biting me14:53
@iglesiasgyeah, it seems to have proper tests, awesome14:56
lambdayiglesiasg: it does deep copy when you pass Eigen::Matrix as param.. just checked14:56
@iglesiasglambday: will try to keep that in mind from now on, thanks!14:57
lambdayiglesiasg: I don't understand why should one pass *float with the dimension? :(14:58
@iglesiasgbtw, they brought Linus and Peter Norvig yesterday15:00
@iglesiasglambday: yeah.. I agree with you. It's not the proper way of doing it15:00
@iglesiasglambday: what does rows() return for an Eigen::Map<Eigen::VectorXd>?15:03
@iglesiasglambday: just the vector dimension, right?15:04
lambdayiglesiasg: yes15:04
@iglesiasgcool, thanks15:04
lambdayiglesiasg: I guess the easiest way would be to change the function params to SG.. even if you pass Eigen matrix due to the eigen constructor in SG it should do the conversion automatically... then inside the function we can use map from SG15:05
lambdayoh but it uses eigen map instead.. that won't work then15:07
lambdaysorry about the confusion15:07
@wikingi'm totally puzzled by this issues15:09
@wikinghttps://github.com/shogun-toolbox/shogun/issues/253815:09
@wikingiglesiasg: still here?15:13
@iglesiasgyep15:13
@iglesiasgthe Eigen__MatrixXt thingies still appear in the modshogunPYTHON*15:14
@iglesiasgI am double checking it though..15:15
@wikingiglesiasg: do you know why SGString doesn't have a destructor?15:15
@iglesiasgamazing15:15
@iglesiasgwiking: destroy_string() xD15:16
@wikingiglesiasg: ok yeah but like a real dtor15:16
@wiking~SGString()15:16
@wikingok i'll make one :)15:17
@iglesiasgwiking: yeah, I got you. I found it funny that there's this destroy_string that is called from nowhere haha15:17
@wikingiglesiasg: mmm maybe i should just drop then destroy_string and free_string15:18
@wikingmmm ok no15:18
@wikingi'll just remove destroy_string15:18
@wikinglambday: how do i force to turn off viennacl?15:30
@wiking-DVIENNACL_FOUND=OFF doesn't work15:30
lambdaywiking: checking15:31
lambdaywiking: HAVE_VIENNACL is the macro...15:32
lambdaywiking: I'm afraid current it's not done15:34
lambdaywiking: if the package is not found only then it will say viennacl missing15:34
lambdayCMakeLists.txt:65115:35
lambdaywiking: maybe define another variable for this? if that's turned off then we'll find the viennacl pkg15:36
@iglesiasgwiking: so it was not only this thing in SingleLaplacianInferenceMethodWithLBFGS15:42
@iglesiasgeigen is leaking into swig somewhere else too15:43
@wiking:<15:43
@wikingfuck15:43
@wikingiglesiasg: have u compiled the thing from scratch15:43
@wikingrm -rf build15:43
@iglesiasgrm -rf build15:43
@iglesiasgyes15:43
@iglesiasgbut it is so nuts this thing of the memory comsumption w/ and w/o eigen15:44
@iglesiasg2GB and ~0.5GB15:44
@wikingfuck15:44
@wikingmmm is it really 0.5GB15:44
@wikingi never seen swig requiring oonly 0.5 :P15:44
@iglesiasgwiking: compile PythonModular w/o Eigen :-)15:45
@lisitsynhah15:45
@lisitsynreally?15:45
@iglesiasgI wanted to double check this though in case I missed something yesterday15:45
@lisitsynswig + eigen = 2gb of ram?15:45
@iglesiasglet me do it now15:45
@lisitsynand w/o just 0.5?15:45
@iglesiasglisitsyn: let me double check, I might be saying just bullshit15:46
@lisitsyniglesiasg: I wish it is true as it sounds awesome15:46
@lisitsyniglesiasg: what if we remove std? :D15:46
@lisitsyn0.1gb? ;)15:46
@wikingi mean the thing is that afaik modular interface packages are not being generated for ubuntu15:46
@wikingbecause it uses 4G+ ram15:46
shogun-buildbotbuild #444 of debian wheezy - memcheck is complete: Failure [failed memory check]  Build details are at http://buildbot.shogun-toolbox.org/builders/debian%20wheezy%20-%20memcheck/builds/444  blamelist: Heiko Strathmann <heiko.strathmann@gmail.com>16:21
@iglesiasgwiking: lisitsyn: mistery solved16:35
@iglesiasgit was ccache..16:35
@wikingiglesiasg: lol16:37
@wikingiglesiasg: ok push the fix then16:37
@wikinglet's see how travis reacts16:37
@iglesiasgwiking: all right16:37
@wikingas usually the modular jobs were dying because of insufficient mem16:37
@iglesiasgwiking: not very strict measure probably, but it reduced it about 100mb16:38
@iglesiasgI mean the refactoring16:38
@iglesiasgwiking: but I think it is worth to investigate this thing of Eigen__MatrixXt in modshogunPYTHON_wrap.cxx. I don't see any reason why there should any Eigen related thing in there16:39
@iglesiasgwiking: what do you think?16:39

@iglesiasglambday: we were discussing about this kind of thing yesterday, this is not really the best way of handling this issue, right?17:12
@iglesiasglambday: I mean, these classes that need eigen or other dependencies should just not be part of an interface17:13
@iglesiasgno matter whether this interface is going to be visible for swig or for users17:13
@iglesiasglambday: what do you think?17:13
lambdayiglesiasg: well, this stuff should really not be exposed to swig - its used internally in linalg and which makes it actually possible to work with different types of matrices in Eigen and ViennaCL17:13
@iglesiasglambday: exactly17:14

@iglesiasgwiking: patch is in, let's see what travis thinks17:21
@iglesiasglambday: they are indeed not in the .i files. Still, it might be the cause of Eigen__MatrixT in swig if they are included in another header that swig has to look at. I will test it and get back later17:26

@lisitsyniglesiasg: I think it handles whatever he sees21:41
iglesiasgbut the attributes are "always" private21:41
@lisitsyniglesiasg: plus21:41

@HeikoSlisitsyn: but I would love to have this23:28

@HeikoSlisitsyn: we talked a lot about refactoring shoguns internals and do proper software engineering23:29
@HeikoSlisitsyn: separate algorihtms and core framework23:29
@HeikoSlisitsyn: maybe dropping parameter interface23:30
@HeikoSlisitsyn: etc23:30
@HeikoSlisitsyn: well write it down soon23:30
@HeikoSlisitsyn: aer is also cool23:30
@lisitsynHeikoS: ok cool23:30
@HeikoSlisitsyn: but thoralf suggested to drop parameters maybe completely, we should definitely talk about this23:30
@HeikoSlisitsyn: I am sure we can get shogun pretty light weight using this23:30
@lisitsynHeikoS: if we can drop parameters at all it could be cool23:30
@lisitsynbut how?23:30
@HeikoSlisitsyn: thoralf also currently builds a script that allow to only compile a certain number of classes23:30
@HeikoSlisitsyn: we loose serialisation, model-selection (might drop anyway), clone and equals23:31
@HeikoSlisitsyn: alternative: do it properly without all this overhead in the base classes23:31
@HeikoSlisitsyn: it really blows up compile time I think, but we would have to  investigate that23:31
