| sonne|work | wiking: so did you have time to fiddle with the hedonismbot? | 11:48 |
|---|---|---|
| @wiking | sonne|work: yeah it's up and running | 11:54 |
| @wiking | sonne|work: i still have to move some tasks from fatbot | 11:54 |
| sonne|work | wiking: yeah makes sense to move all compile stuff over | 11:55 |
| @wiking | but i've already added the a new trusty job + opencl tests | 11:55 |
| sonne|work | wiking: nice! | 11:55 |
| @wiking | sonne|work: only thing is missing actually to move the basic libshogun + modular and static test to hedonism | 11:55 |
| @wiking | all the buildbot related chroots are moved to hedonisms | 11:56 |
| sonne|work | wiking: so sounds like you did almost all the work already | 11:58 |

| Guest14866 | Hi, 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 |

| @wiking | pong | 15:21 |
| Guest14866 | I 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 method | 15:21 |
| @wiking | besser82: pong | 15:21 |
| Guest14866 | ... via python! | 15:22 |
| @wiking | Guest14866: what SerializableFile type are u using? | 15:22 |
| Guest14866 | Neither Ascii nor Binary does work | 15:23 |
| @wiking | binary? | 15:23 |
| @wiking | what binary r u trying? | 15:23 |
| @wiking | mm Guest14866 ok can u actually paste how do you try to serialize SVM? | 15:24 |
| @wiking | just paste the snippet of the code to pastebin.com | 15:24 |
| @besser82 | wiking, can you give me a user-acc for sg-hp on django, plz? | 15:24 |
| @wiking | besser82: mmmm | 15:24 |
| @wiking | lemme see if i can | 15:24 |
| @besser82 | wiking, HeikoS cannot... So you, Fernando and S?ren are left ;) | 15:25 |
| @wiking | besser82: gimme pub key | 15:25 |
| Guest14866 | The 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 |
| @besser82 | wiking, query ^^ | 15:26 |
| @wiking | Guest14866: have u checked this example actually: examples/undocumented/python_modular/serialization_complex_example.py | 15:27 |
| @wiking | ok | 15:27 |
| @wiking | besser82: you should be able to update now the site | 15:27 |
| @besser82 | wiking, many thx ^^ | 15:28 |
| @wiking | besser82: simply run 'make release' in shogun-web directory | 15:28 |
| @besser82 | wiking, can you give me push acc to that repo as well, plz?!? | 15:28 |
| @wiking | besser82: u dont have? | 15:29 |
| @wiking | k | 15:29 |
| @wiking | just a sec | 15:29 |
| @besser82 | wiking, nope, not yet... only sg && sg-data... | 15:29 |
| @wiking | besser82: done added | 15:30 |
| @besser82 | wiking, 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 |
| @wiking | Guest14866: mmm how big is your training set? | 15:34 |
| Guest14866 | @wiking: 400 examples and each feature vector has a length of 3000 | 15:35 |
| @wiking | Guest14866: what you could try to speed up the serialization of the svm | 15:36 |
| @wiking | to clear it's features | 15:36 |
| @wiking | r u using kernels? | 15:37 |
| Guest14866 | does is suffice to save the kernel only? | 15:38 |
| @wiking | so you r using MulticlassLibSVM with a kernel? | 15:38 |
| Guest14866 | @wiking: linear kernel | 15:38 |
| Guest14866 | yes | 15:38 |
| @wiking | linear kernel? | 15:38 |
| @wiking | why dont u use then liblinear? | 15:38 |
| Guest14866 | we have already tried different configurations | 15:39 |
| @wiking | ah i see | 15:39 |
| @wiking | no worries | 15:39 |
| @wiking | well | 15:39 |
| @wiking | how slow is slow? | 15:39 |
| @wiking | could you save it at least | 15:39 |
| @wiking | or not at all? | 15:39 |
| Guest14866 | it takes longer than to train it :) | 15:40 |
| @wiking | and how big was the serialized file if u managed to save it | 15:40 |
| @wiking | jesus | 15:40 |
| Guest14866 | you see.. :) | 15:40 |
| @wiking | but have u managed it on the end | 15:40 |
| @wiking | or not ? | 15:40 |
| Guest14866 | yes | 15:40 |
| Guest14866 | but it was very huge, the filesize was ... just a moment | 15:40 |
| @wiking | ok | 15:41 |
| Guest14866 | 280 mb | 15:41 |
| @wiking | Guest14866: do u still have the file? | 15:41 |
| Guest14866 | yes | 15:41 |
| @wiking | can u share it? | 15:41 |
| Guest14866 | yes, but it will take some time to upload :) | 15:42 |
| @wiking | i can wait :) | 15:42 |
| @wiking | Guest14866: but please send me a reminding to wiking@maeth.com | 15:42 |
| @wiking | as i'm going to go to sleep soonish | 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 |
| @besser82 | sonney2k_, nope ^^ | 23:19 |
| @besser82 | sonney2k_, compile time with cereal is actually pretty fast | 23:20 |
| @besser82 | sonney2k_, and from code pov it is even real simple stuff and not even comparable to boost-serialize | 23:21 |
| @wiking | sonney2k_: it's header only lib... not like boost | 23:21 |
| @wiking | sonney2k_: we have to change serialization/parameter fw as the current one is unmaintainable... | 23:26 |
