@wikingwhy do we assume in case of serialisation that a template class will always get a builtintype as template arg?11:43
lisitsynwiking: all template classes are specialized in C++ IIRC11:44
lisitsynerr11:44
lisitsyn.cpp11:44
lisitsyn:D11:44
lisitsynnot C++11:44
@wikinglisitsyn: i'm talking about class_list.cpp11:46
@wikinglisitsyn: so it's generated in a way that if there's a TEMPLATE11:46
@wikingthen it'll generate like TemplateClass<PT_*>11:46
@wikinge.g. TemplateClass<bool> etc.11:47
lisitsynyes11:47
lisitsynwhat's wrong?11:47
@wikingbut what if a template is not like that?:)11:47
lisitsynMyClass<OtherClass>?11:47
@wikingso that it's template argument is actually not a PT_*11:47
@wikingyeah something like that11:47
lisitsynthrow new FuckYouException();11:48
lisitsynjk :D11:48
@wiking:D11:48
lisitsynwiking: well it is not supported as Soeren used templates only to provide various feature types11:48

lisitsynpickle27: yo howdy16:46
pickle27lisitsyn: hey!16:46
pickle27lisitsyn: I actually have a question for you16:47
pickle27I was looking into making a getter for the time separated covariance matrices as per the emails with Andreas16:48
pickle27but they are SGNDArrays16:48
pickle27so I made the getter but it is of no use from python_modular16:48
pickle27so wondering what the options are16:49
lisitsynpickle27: what do you mean by is of no use?16:49
pickle27well it returns an SGNDArray swig obj16:49
pickle27but there is no way to get the data from it16:49
lisitsynahh16:49
pickle27the get_matrix returns a pointer16:49
pickle27so one option is to make a new method for NDArray that returns SGMatrix16:50
pickle27or make the getter take a number and return that MAtrix from the Array and not change the Array class16:50
lisitsynpickle27: something must be wrong with typemaps16:51
lisitsynthat's essentially it16:51
lisitsynpickle27: could you show me the method?16:52
pickle27I don't think anything is wrong with the typemaps this situation just isn't accounted for16:52
pickle27here16:52
pickle27SGNDArray<float64_t> CFFSep::get_covs() const16:52
pickle27{16:52
pickle27return m_covs;16:52
pickle27}16:52
pickle27if I used it in python and print the return val I get:16:54
pickle27<Swig Object of type 'shogun::SGNDArray< double > *' at 0x245cdc0>16:54
pickle27and if I try to access the data using .array or using get_matrix(0) I get something like this:16:55
pickle27<Swig Object of type 'shogun::T_ALPHA_BETA_TABLE *' at 0x251adf8>16:55
lisitsynpickle27: looks quite strange indeed17:15
lisitsynalpha beta table is something from the outer space17:17
pickle27haha17:17
lisitsynhow can that be here :)17:17
lisitsynI didn't even know we have such a class17:17
pickle27lisitsyn: I think its because its a pointer17:17
-!- foulwall [~user@2001:da8:215:c252:f035:404c:df34:eab8] has joined #shogun17:18
lisitsynpickle27: as a workaround I can suggest to add get_cov(int)17:18
pickle27lisitsyn: thats what I was thinking17:18
lisitsynthat returns slices of the n-d array17:18
pickle27lisitsyn: the other option would be to create a new method for SGNDArray that does the same17:19
pickle27but how to name it to avoid confusion with the C++ method that returns a pointer17:19
lisitsynpickle27: actually as we have typemaps we just have to fix it17:22
lisitsyniglesiasg: have you used nd array typemaps?17:22
pickle27lisitsyn: oh we actually do have a typemap for NDArray17:23
pickle27I didn't think we did17:23
pickle27lisitsyn: looks like we might only have a "from" and we need a "to"17:24
lisitsynpickle27: yeah I thought about it17:26
lisitsynpickle27: could you please check if it is really true17:26
lisitsynjust check what is missed for sgndarray compared to sgmatrix17:26
pickle27lisitsyn: yeah I think I see it17:27
pickle27lisitsyn: this will have to be done for each modular interface yes?17:27
lisitsynpickle27: yeah unfortunately17:28
pickle27lisitsyn: okay I'll try and do for python today and maybe octave17:28
pickle27I may just submit an issue on github for the remaining for now17:29

@HeikoSgsomix_: will be interesting very soon for me! :)19:57
@HeikoSbut for now, just how to map19:57
gsomix_HeikoS, there is a little doc in swig_typemaps.i for python modular interface.19:59
gsomix_HeikoS, spmatrix_from_numpy func19:59
@HeikoSyep there I found the csc20:00
@HeikoScool thanks20:00
gsomix_ok20:00

@sonney2kHeikoS, yes well just use a sparse structure20:11
@HeikoSsonney2k: doesnt work, have to convert to csc20:11
@sonney2kHeikoS, any news about your bank account?20:11
@HeikoSbut that works20:11
@HeikoSsonney2k: parents return end of august20:12
@sonney2kHeikoS, so one more week20:12
@HeikoSyep20:12
@HeikoSthe it works immediately20:12
@sonney2kHeikoS, which language python?20:12
@HeikoSyes20:12
@sonney2kHeikoS, then look at the python examples that use sparse20:12
@HeikoSthats what I did finally20:13
@sonney2kHeikoS, but I guess I don't really understand the question20:13
@sonney2kwell you should do that as a *first* step always right?20:13
@sonney2kso it works now right?20:13
pickle27hey guys, I was working on the typemaps earlier, I added an out typemap for SGNDArray in python20:13
@HeikoSthe mapping SGSparseMatrix to  scipy.sparsematrix doesnt work20:13
pickle27then I started looking at octave20:14
@HeikoSonly the csc(scipy.sparse)20:14
@HeikoSanyway20:14
pickle27and I got a bit confused20:14
pickle27sonney2k: got a second to look at it with me?20:14
@sonney2kHeikoS, yes sure only csc sparse matrix works20:14
@HeikoSsonney2k: I did not know that :)20:15
@sonney2kHeikoS, there are 3 formats and csc is the one we support20:15
@HeikoSok, going home now, see you!20:15
@sonney2kHeikoS, wait20:15
@HeikoSyes?20:15
@sonney2kHeikoS, did you plan your trip already?20:15
@HeikoSnope20:15
@HeikoSnothing20:15
@sonney2kI am asking because renting a car would make sense if we all use it20:16
@HeikoSsonney2k: I am totally up for that!20:16
@HeikoSare you around tomorrow? I am a bit late here and should go soon20:16
@HeikoSok gotta go, bye! I will be around tomorrow all day20:18

pickle27sonney2k: can I get your help with the octave typemaps for a sec20:19
pickle27Im trying to add support for SGNDArray20:19
@sonney2kpickle27, what is the issue?22:11
@sonney2kgsomix_, and what was your question?22:16
@sonney2kwiking, ?22:16
@sonney2kwiking, what do you use to chat with under osx?22:17
@wikingsonney2k: mmm i used to use22:17
@wikingcolloquy22:17
@wikingbut i'm irssi now22:17
@sonney2kwiking, woah hardcore :)22:18
@sonney2kwiking, did you manage to uploade some videos?22:19
gsomix_sonney2k, about SGVector.22:22
gsomix_sonney2k, is there nice method for work with SGVector+offsets?22:23
@sonney2kgsomix_, errm??22:23
@sonney2kgsomix_, as in vec[i] ?22:23
@sonney2kor vec[i+offs] ?22:23
gsomix_nope. look. I need substrings from SGVector.22:25
gsomix_without copying22:25
gsomix_on same memory22:25
gsomix_but with offset.22:25
gsomix_something like SGVector<char> substring=string.get_vector_with_offset(offset, length), where string is SGVector<char>22:26
@sonney2kgsomix_, you could do dangerous stuff like offsetted= SGVector(vec.vector+offs, vec.vlen, false)22:26
gsomix_sonney2k, yep, without refcount.22:26
@sonney2kyeah22:26
@sonney2kwith vec.vlen-offs22:26
gsomix_I'm just curious is there refcounted solution.22:27
@sonney2kgsomix_, impossible!22:27
@sonney2kwell hmmhh22:27
gsomix_hm, I can imagine extended SGVector, that contains vector, physical length, offset and logical length. but in this case SGVector is not lightweight22:28
gsomix_but it would be very useful for parsing22:29
gsomix_now there are many, many copying and mallocs.22:30
gsomix_but, of course, I can use unsafe solution22:31
gsomix_sonney2k, ok, and I have another question. is there better solution for parsing numbers from strings than atoi/strtol?22:33
gsomix_I mean atoi/strtol requires zero-terminated strings22:33
gsomix_I cannot use it on pure memory block of data that read from file22:34
gsomix_sonney2k, maybe do you know solution for non-zero-terminated strings? for strings with defined length22:35
@sonney2kgsomix_, no sorry - I would just put a '\0' there and change it back afterwards :/22:42
@sonney2kgsomix_, well a safe solution would be to keep one SGVector around22:43
@sonney2kand then work with an offsetted SGVector22:43
@sonney2kwell or you derive some SGVectorView class from SGVector where you in addition store such an offset22:45
@sonney2kSGVector is not *that* lightweight since it has a vtable already...22:45
gsomix_sonney2k, ok, thanks!22:46
@sonney2kactually not derive but make SGVector a member of SGVectorView22:46
gsomix_sonney2k, it would be good solution for parsing.22:47
gsomix_I mean then I can store SGVectorView in dynarray's or so22:48
gsomix_sonney2k, one question about get_sparse_vector.22:49
gsomix_I should just read one line from libsvm file and parse it, right?22:49
gsomix_there is no reason to read whole file, hm22:50
@sonney2kgsomix_, when you want to store that in dyn* you need to add some stuff to lib/memory.{cpp,h}22:53
@sonney2kgsomix_, yeah for sparse it doesn't help because we store vectors separately anyway22:53
gsomix_sonney2k, do you mean I should enable SG_SPECIALIZED_MALLOC for new class? because it's not SGObject, right?22:56
@sonney2kgsomix_, well except if you parse it into a dense SGMatrix22:56
@sonney2kgsomix_, it is because it needs inplace new operator :/22:59
gsomix_sonney2k, ok, I'll try to get into it.23:02
gsomix_now need finish sparse reading for libsvm and csv23:02
@wikingsonney2k: yeah i have the python script + client api code from googs23:03
@wikingso i'm on it23:03

shogun-notifier-shogun: update news23:22
@wikingsonney2k what ya think about breaking up the swig modular interface into smaller _wrapper.cxx-es23:28
@wikingat least then the compilation could be done parallel (with make -jX)23:29
gsomix_wiking, I'm not Soeren, but would be great.23:30
gsomix_wiking, but how?23:30
@wikingsonney2k: and i was thiking that we'd need need a nightly of osx23:30
