sonne|workwiking: so did you have time to fiddle with the hedonismbot?11:48
@wikingsonne|work: yeah it's up and running11:54
@wikingsonne|work: i still have to move some tasks from fatbot11:54
sonne|workwiking: yeah makes sense to move all compile stuff over11:55
@wikingbut i've already added the a new trusty job + opencl tests11:55
sonne|workwiking: nice!11:55
@wikingsonne|work: only thing is missing actually to move the basic libshogun + modular and static test to hedonism11:55
@wikingall the buildbot related chroots are moved to hedonisms11:56
sonne|workwiking: so sounds like you did almost all the work already11:58

Guest14866Hi, I am just trying to save and load files in python by the SHOGUN SVM with save_serializable and load_serializable but this is freaking slow and I think I am just misusing it for my requirement. Can you tell me how to do it in a proper way?15:20
@besser82wiking, ping?15:21

@wikingpong15:21
Guest14866I have already tried the wrapped method bool save (FILE *svm_file) but I don't know which file descriptor I have to pass to this method15:21
@wikingbesser82: pong15:21
Guest14866... via python!15:22
@wikingGuest14866: what SerializableFile type are u using?15:22
Guest14866Neither Ascii nor Binary does work15:23
@wikingbinary?15:23
@wikingwhat binary r u trying?15:23
@wikingmm Guest14866 ok can u actually paste how do you try to serialize SVM?15:24
@wikingjust paste the snippet of the code to pastebin.com15:24
@besser82wiking, can you give me a user-acc for sg-hp on django, plz?15:24
@wikingbesser82: mmmm15:24
@wikinglemme see if i can15:24
@besser82wiking, HeikoS cannot... So you, Fernando and S?ren are left  ;)15:25
@wikingbesser82: gimme pub key15:25
Guest14866The problem is, save_serializable gives us a file, but the save(..) routine of MulticlassLibSVM has been wrapped to accept FILE* as its first argument. How does one specify a C FILE pedant in python? Or is a wrapper for this function not available?15:26
@besser82wiking, query ^^15:26
@wikingGuest14866: have u checked this example actually: examples/undocumented/python_modular/serialization_complex_example.py15:27
@wikingok15:27
@wikingbesser82: you should be able to update now the site15:27
@besser82wiking, many thx ^^15:28
@wikingbesser82: simply run 'make release' in shogun-web directory15:28
@besser82wiking, can you give me push acc to that repo as well, plz?!?15:28
@wikingbesser82: u dont have?15:29
@wikingk15:29
@wikingjust a sec15:29
@besser82wiking, nope, not yet...  only sg && sg-data...15:29
@wikingbesser82: done added15:30
@besser82wiking, many thanks ^^  just got mail ^^15:31
Guest14866@wiking: Yes, thank you for the link but I already tried this examples but each of it is very slow and so I guessed that there is another way to do it?15:32
@wikingGuest14866: mmm how big is your training set?15:34
Guest14866@wiking: 400 examples and each feature vector has a length of 300015:35
@wikingGuest14866: what you could try to speed up the serialization of the svm15:36
@wikingto clear it's features15:36
@wikingr u using kernels?15:37
Guest14866does is suffice to save the kernel only?15:38
@wikingso you r using MulticlassLibSVM with a kernel?15:38
Guest14866@wiking: linear kernel15:38
Guest14866yes15:38
@wikinglinear kernel?15:38
@wikingwhy dont u use then liblinear?15:38
Guest14866we have already tried different configurations15:39
@wikingah i see15:39
@wikingno worries15:39
@wikingwell15:39
@wikinghow slow is slow?15:39
@wikingcould you save it at least15:39
@wikingor not at all?15:39
Guest14866it takes longer than to train it :)15:40
@wikingand how big was the serialized file if u managed to save it15:40
@wikingjesus15:40
Guest14866you see.. :)15:40
@wikingbut have u managed it on the end15:40
@wikingor not ?15:40
Guest14866yes15:40
Guest14866but it was very huge, the filesize was ... just a moment15:40
@wikingok15:41
Guest14866280 mb15:41
@wikingGuest14866: do u still have the file?15:41
Guest14866yes15:41
@wikingcan u share it?15:41
Guest14866yes, but it will take some time to upload :)15:42
@wikingi can wait :)15:42
@wikingGuest14866: but please send me a reminding to wiking@maeth.com15:42
@wikingas i'm going to go to sleep soonish15:43
Guest14866sure, thanks a lot!15:43

sonney2k_wiking, ceral smells like serious code bloat and looks exactly like the boost stuff (which did increase compile time and code size by like factor 10)23:10
@besser82sonney2k_, nope ^^23:19
@besser82sonney2k_, compile time with cereal is actually pretty fast23:20
@besser82sonney2k_, and from code pov it is even real simple stuff and not even comparable to boost-serialize23:21
@wikingsonney2k_: it's header only lib... not like boost23:21
@wikingsonney2k_: we have to change serialization/parameter fw as the current one is unmaintainable...23:26
@wikingsonney2k_: https://github.com/thekvs/cpp-serializers23:41
