| @wiking | why do we assume in case of serialisation that a template class will always get a builtintype as template arg? | 11:43 |
| lisitsyn | wiking: all template classes are specialized in C++ IIRC | 11:44 |
| lisitsyn | err | 11:44 |
| lisitsyn | .cpp | 11:44 |
| lisitsyn | :D | 11:44 |
| lisitsyn | not C++ | 11:44 |
| @wiking | lisitsyn: i'm talking about class_list.cpp | 11:46 |
| @wiking | lisitsyn: so it's generated in a way that if there's a TEMPLATE | 11:46 |
| @wiking | then it'll generate like TemplateClass<PT_*> | 11:46 |
| @wiking | e.g. TemplateClass<bool> etc. | 11:47 |
| lisitsyn | yes | 11:47 |
| lisitsyn | what's wrong? | 11:47 |
| @wiking | but what if a template is not like that?:) | 11:47 |
| lisitsyn | MyClass<OtherClass>? | 11:47 |
| @wiking | so that it's template argument is actually not a PT_* | 11:47 |
| @wiking | yeah something like that | 11:47 |
| lisitsyn | throw new FuckYouException(); | 11:48 |
| lisitsyn | jk :D | 11:48 |
| @wiking | :D | 11:48 |
| lisitsyn | wiking: well it is not supported as Soeren used templates only to provide various feature types | 11:48 |

| lisitsyn | pickle27: yo howdy | 16:46 |
| pickle27 | lisitsyn: hey! | 16:46 |
| pickle27 | lisitsyn: I actually have a question for you | 16:47 |
| pickle27 | I was looking into making a getter for the time separated covariance matrices as per the emails with Andreas | 16:48 |
| pickle27 | but they are SGNDArrays | 16:48 |
| pickle27 | so I made the getter but it is of no use from python_modular | 16:48 |
| pickle27 | so wondering what the options are | 16:49 |
| lisitsyn | pickle27: what do you mean by is of no use? | 16:49 |
| pickle27 | well it returns an SGNDArray swig obj | 16:49 |
| pickle27 | but there is no way to get the data from it | 16:49 |
| lisitsyn | ahh | 16:49 |
| pickle27 | the get_matrix returns a pointer | 16:49 |
| pickle27 | so one option is to make a new method for NDArray that returns SGMatrix | 16:50 |
| pickle27 | or make the getter take a number and return that MAtrix from the Array and not change the Array class | 16:50 |
| lisitsyn | pickle27: something must be wrong with typemaps | 16:51 |
| lisitsyn | that's essentially it | 16:51 |
| lisitsyn | pickle27: could you show me the method? | 16:52 |
| pickle27 | I don't think anything is wrong with the typemaps this situation just isn't accounted for | 16:52 |
| pickle27 | here | 16:52 |
| pickle27 | SGNDArray<float64_t> CFFSep::get_covs() const | 16:52 |
| pickle27 | { | 16:52 |
| pickle27 | return m_covs; | 16:52 |
| pickle27 | } | 16:52 |
| pickle27 | if 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 |
| pickle27 | and 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 |
| lisitsyn | pickle27: looks quite strange indeed | 17:15 |
| lisitsyn | alpha beta table is something from the outer space | 17:17 |
| pickle27 | haha | 17:17 |
| lisitsyn | how can that be here :) | 17:17 |
| lisitsyn | I didn't even know we have such a class | 17:17 |
| pickle27 | lisitsyn: I think its because its a pointer | 17:17 |
| -!- foulwall [~user@2001:da8:215:c252:f035:404c:df34:eab8] has joined #shogun | 17:18 | |
| lisitsyn | pickle27: as a workaround I can suggest to add get_cov(int) | 17:18 |
| pickle27 | lisitsyn: thats what I was thinking | 17:18 |
| lisitsyn | that returns slices of the n-d array | 17:18 |
| pickle27 | lisitsyn: the other option would be to create a new method for SGNDArray that does the same | 17:19 |
| pickle27 | but how to name it to avoid confusion with the C++ method that returns a pointer | 17:19 |
| lisitsyn | pickle27: actually as we have typemaps we just have to fix it | 17:22 |
| lisitsyn | iglesiasg: have you used nd array typemaps? | 17:22 |
| pickle27 | lisitsyn: oh we actually do have a typemap for NDArray | 17:23 |
| pickle27 | I didn't think we did | 17:23 |
| pickle27 | lisitsyn: looks like we might only have a "from" and we need a "to" | 17:24 |
| lisitsyn | pickle27: yeah I thought about it | 17:26 |
| lisitsyn | pickle27: could you please check if it is really true | 17:26 |
| lisitsyn | just check what is missed for sgndarray compared to sgmatrix | 17:26 |
| pickle27 | lisitsyn: yeah I think I see it | 17:27 |
| pickle27 | lisitsyn: this will have to be done for each modular interface yes? | 17:27 |
| lisitsyn | pickle27: yeah unfortunately | 17:28 |
| pickle27 | lisitsyn: okay I'll try and do for python today and maybe octave | 17:28 |
| pickle27 | I may just submit an issue on github for the remaining for now | 17:29 |
| lisitsyn | pickle27: yeah please submit it | 17:31 |

| iglesiasg | lisitsyn, no, I don't think I have, why? | 18:48 |
| pickle27 | iglesiasg: we were trying to see if anyone had tested them | 18:56 |
| pickle27 | iglesiasg: I think I found the issue though - there was only an in typemap and not an out | 18:56 |
| iglesiasg | pickle27, I just read the logs and got a bit updated | 18:56 |
| iglesiasg | pickle27, how is it going with it? | 18:56 |
| pickle27 | iglesiasg: actually just ran it for python and it looks good | 18:56 |
| pickle27 | wiking: is there a way to force the interfaces to rebuild? I seem to have to keep rebuilding from scratch in order for them to update | 19:03 |

| @HeikoS | hi | 19:47 |
| @HeikoS | sonney2k, wiking do you know whether and how to do modular access to sparse matrices? | 19:47 |
| @HeikoS | is that even supported yet? | 19:47 |
| @HeikoS | gsomix_: are you around? | 19:51 |
| gsomix_ | HeikoS, hey | 19:55 |
| @HeikoS | gsomix_: hi | 19:55 |
| gsomix_ | HeikoS, I should add our libsvm reader to modular interfaces. | 19:55 |
| @HeikoS | just wondering what to do to make swig accept sparse matrices? | 19:55 |
| @HeikoS | gsomix_: yep that would be nice, but currently even using python to create them | 19:55 |
| @HeikoS | csc_matrix? | 19:56 |
| @HeikoS | ah yes that did the job for me | 19:56 |
| @HeikoS | gsomix_: I am asking you since you did some typemaps for sparse matrices | 19:57 |
| gsomix_ | HeikoS, ahh, sorry. I thought you were about reading. =___= | 19:57 |
| @HeikoS | gsomix_: will be interesting very soon for me! :) | 19:57 |
| @HeikoS | but for now, just how to map | 19:57 |
| gsomix_ | HeikoS, there is a little doc in swig_typemaps.i for python modular interface. | 19:59 |
| gsomix_ | HeikoS, spmatrix_from_numpy func | 19:59 |
| @HeikoS | yep there I found the csc | 20:00 |
| @HeikoS | cool thanks | 20:00 |
| gsomix_ | ok | 20:00 |
| -!- lambday [67157e37@gateway/web/freenode/ip.103.21.126.55] has quit [Ping timeout: 250 seconds] | 20:04 | |
| @sonney2k | HeikoS, yes well just use a sparse structure | 20:11 |
| @HeikoS | sonney2k: doesnt work, have to convert to csc | 20:11 |
| @sonney2k | HeikoS, any news about your bank account? | 20:11 |
| @HeikoS | but that works | 20:11 |
| @HeikoS | sonney2k: parents return end of august | 20:12 |
| @sonney2k | HeikoS, so one more week | 20:12 |
| @HeikoS | yep | 20:12 |
| @HeikoS | the it works immediately | 20:12 |
| @sonney2k | HeikoS, which language python? | 20:12 |
| @HeikoS | yes | 20:12 |
| @sonney2k | HeikoS, then look at the python examples that use sparse | 20:12 |
| @HeikoS | thats what I did finally | 20:13 |
| @sonney2k | HeikoS, but I guess I don't really understand the question | 20:13 |
| @sonney2k | well you should do that as a *first* step always right? | 20:13 |
| @sonney2k | so it works now right? | 20:13 |
| pickle27 | hey guys, I was working on the typemaps earlier, I added an out typemap for SGNDArray in python | 20:13 |
| @HeikoS | the mapping SGSparseMatrix to scipy.sparsematrix doesnt work | 20:13 |
| pickle27 | then I started looking at octave | 20:14 |
| @HeikoS | only the csc(scipy.sparse) | 20:14 |
| @HeikoS | anyway | 20:14 |
| pickle27 | and I got a bit confused | 20:14 |
| pickle27 | sonney2k: got a second to look at it with me? | 20:14 |
| @sonney2k | HeikoS, yes sure only csc sparse matrix works | 20:14 |
| @HeikoS | sonney2k: I did not know that :) | 20:15 |
| @sonney2k | HeikoS, there are 3 formats and csc is the one we support | 20:15 |
| @HeikoS | ok, going home now, see you! | 20:15 |
| @sonney2k | HeikoS, wait | 20:15 |
| @HeikoS | yes? | 20:15 |
| @sonney2k | HeikoS, did you plan your trip already? | 20:15 |
| @HeikoS | nope | 20:15 |
| @HeikoS | nothing | 20:15 |
| @sonney2k | I am asking because renting a car would make sense if we all use it | 20:16 |
| @HeikoS | sonney2k: I am totally up for that! | 20:16 |
| @HeikoS | are you around tomorrow? I am a bit late here and should go soon | 20:16 |
| @HeikoS | ok gotta go, bye! I will be around tomorrow all day | 20:18 |

| pickle27 | sonney2k: can I get your help with the octave typemaps for a sec | 20:19 |
| pickle27 | Im trying to add support for SGNDArray | 20:19 |
| @sonney2k | pickle27, what is the issue? | 22:11 |
| @sonney2k | gsomix_, and what was your question? | 22:16 |
| @sonney2k | wiking, ? | 22:16 |
| @sonney2k | wiking, what do you use to chat with under osx? | 22:17 |
| @wiking | sonney2k: mmm i used to use | 22:17 |
| @wiking | colloquy | 22:17 |
| @wiking | but i'm irssi now | 22:17 |
| @sonney2k | wiking, woah hardcore :) | 22:18 |
| @sonney2k | wiking, 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 |
| @sonney2k | gsomix_, errm?? | 22:23 |
| @sonney2k | gsomix_, as in vec[i] ? | 22:23 |
| @sonney2k | or vec[i+offs] ? | 22:23 |
| gsomix_ | nope. look. I need substrings from SGVector. | 22:25 |
| gsomix_ | without copying | 22:25 |
| gsomix_ | on same memory | 22:25 |
| 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 |
| @sonney2k | gsomix_, you could do dangerous stuff like offsetted= SGVector(vec.vector+offs, vec.vlen, false) | 22:26 |
| gsomix_ | sonney2k, yep, without refcount. | 22:26 |
| @sonney2k | yeah | 22:26 |
| @sonney2k | with vec.vlen-offs | 22:26 |
| gsomix_ | I'm just curious is there refcounted solution. | 22:27 |
| @sonney2k | gsomix_, impossible! | 22:27 |
| @sonney2k | well hmmhh | 22:27 |
| gsomix_ | hm, I can imagine extended SGVector, that contains vector, physical length, offset and logical length. but in this case SGVector is not lightweight | 22:28 |
| gsomix_ | but it would be very useful for parsing | 22:29 |
| gsomix_ | now there are many, many copying and mallocs. | 22:30 |
| gsomix_ | but, of course, I can use unsafe solution | 22:31 |
| 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 strings | 22:33 |
| gsomix_ | I cannot use it on pure memory block of data that read from file | 22:34 |
| gsomix_ | sonney2k, maybe do you know solution for non-zero-terminated strings? for strings with defined length | 22:35 |
| @sonney2k | gsomix_, no sorry - I would just put a '\0' there and change it back afterwards :/ | 22:42 |
| @sonney2k | gsomix_, well a safe solution would be to keep one SGVector around | 22:43 |
| @sonney2k | and then work with an offsetted SGVector | 22:43 |
| @sonney2k | well or you derive some SGVectorView class from SGVector where you in addition store such an offset | 22:45 |
| @sonney2k | SGVector is not *that* lightweight since it has a vtable already... | 22:45 |
| gsomix_ | sonney2k, ok, thanks! | 22:46 |
| @sonney2k | actually not derive but make SGVector a member of SGVectorView | 22:46 |
| gsomix_ | sonney2k, it would be good solution for parsing. | 22:47 |
| gsomix_ | I mean then I can store SGVectorView in dynarray's or so | 22:48 |
| 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, hm | 22:50 |
| @sonney2k | gsomix_, when you want to store that in dyn* you need to add some stuff to lib/memory.{cpp,h} | 22:53 |
| @sonney2k | gsomix_, yeah for sparse it doesn't help because we store vectors separately anyway | 22:53 |
| gsomix_ | sonney2k, do you mean I should enable SG_SPECIALIZED_MALLOC for new class? because it's not SGObject, right? | 22:56 |
| @sonney2k | gsomix_, well except if you parse it into a dense SGMatrix | 22:56 |
| @sonney2k | gsomix_, 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 csv | 23:02 |
| @wiking | sonney2k: yeah i have the python script + client api code from googs | 23:03 |
| @wiking | so i'm on it | 23:03 |

| @wiking | sonney2k what ya think about breaking up the swig modular interface into smaller _wrapper.cxx-es | 23:28 |
| @wiking | at 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 |
