| -!- gsomix [~gsomix@178.45.72.194] has joined #shogun | 08:23 | |
| blackburn | okay | 09:39 |
|---|---|---|
| @sonney2k | blackburn, so | 09:59 |
| @sonney2k | the 1,1 hack is also suboptimal | 09:59 |
| blackburn | sonney2k: yes because it is needed for each field | 10:00 |
| @sonney2k | blackburn, yeah | 10:00 |
| @sonney2k | and btw the problem exists for sgvector too! | 10:00 |
| blackburn | I do not understand why not to make it (true) | 10:00 |
| @sonney2k | and other referenced data | 10:00 |
| blackburn | by default | 10:00 |
| blackburn | what do we lose there? | 10:00 |
| @sonney2k | we might just get some crashers | 10:00 |
| blackburn | why? | 10:00 |
| @sonney2k | but if we do it we should do it for all SGReferencedData | 10:00 |
| blackburn | what should crash? | 10:01 |
| @sonney2k | blackburn, it could be that we relied on this | 10:01 |
| @sonney2k | e.g. | 10:01 |
| @sonney2k | data pointer is set later | 10:01 |
| @sonney2k | but that is not intended to be freed later | 10:01 |
| blackburn | it sounds like a hack | 10:02 |
| blackburn | do we really use it somewhere? | 10:02 |
| @sonney2k | no idea | 10:02 |
| @sonney2k | we can try | 10:02 |
| blackburn | I do not use it anywhre | 10:02 |
| @sonney2k | but the real patch would just be to remove the 'false' | 10:02 |
| @sonney2k | i.e. | 10:02 |
| @sonney2k | SGMatrix() : SGReferencedData() | 10:02 |
| @sonney2k | etc | 10:02 |
| blackburn | sonney2k: other option is to make serialization take care of ref counts | 10:02 |
| blackburn | it is kind of pain yet | 10:03 |
| @sonney2k | yeah but that we should do later | 10:03 |
| @sonney2k | when we do the CMap trick before serializing objects | 10:04 |
| @sonney2k | for now - we can give it a try | 10:04 |
| blackburn | yes but no time for that now | 10:04 |
| blackburn | argh then we still can release | 10:04 |
| blackburn | :D | 10:04 |
| @sonney2k | maybe it is more consistent anyways to have refcounting=true always | 10:04 |
| blackburn | yes it sounds more consistent for me | 10:04 |
| @sonney2k | let me just do it... | 10:05 |
| blackburn | feel free, I can patch shogun only through github web now :) | 10:05 |
| @sonney2k | blackburn, is there an online vim on github :D | 10:06 |
| @sonney2k | blackburn, btw we don't have SGNDArray converted to referenced yet... | 10:06 |
| blackburn | not the terrible issue | 10:07 |
| @sonney2k | and string / stringlist | 10:07 |

| @sonney2k | blackburn, ^ see - some stuff seems to rely on that behavior | 10:19 |
| @sonney2k | anyway I guess we should rather fix the new crashes than doing it the old way... | 10:19 |
| @sonney2k | gsomix, can you help fixing these? | 10:22 |
| gsomix | sonney2k, hm, what's wrong? | 10:23 |
| blackburn | sonney2k: yes, lets rather fix these crashers | 10:25 |
| blackburn | gsomix: yeah we'd appreciate if you localize it ;) | 10:25 |

| blackburn | hahahah | 10:49 |
| blackburn | yes | 10:49 |
| blackburn | WAT | 10:49 |
| blackburn | lol | 10:49 |
| @sonney2k | blackburn, any idea why we even copy the train labels? | 10:50 |
| @sonney2k | ahh we need it to classify later | 10:50 |
| blackburn | sonney2k: to subtract min label | 10:51 |
| blackburn | pretty idiot thing actually | 10:51 |

| @sonney2k | blackburn, what did you mean 'parsebuffer should be fixed still?' | 10:57 |
| blackburn | sonney2k: it handles vectors in pretty crappy way | 10:58 |
| @sonney2k | blackburn, I really think you should file all the findings we just had as github issues | 10:59 |
| @sonney2k | otherwise this is just forgotten | 10:59 |
| blackburn | sonney2k: I asked gsomix to fix that :) | 10:59 |
| blackburn | what else is to do? | 10:59 |
| @sonney2k | blackburn, sparse stuff still fails - but I don't get it. do you have an idea? | 10:59 |

| @sonney2k | care to share? | 11:03 |
| blackburn | https://github.com/shogun-toolbox/shogun/blob/master/src/shogun/features/SparseFeatures.cpp:373 | 11:03 |
| blackburn | we need to inc ref counter initially | 11:03 |
| blackburn | it should be 2 on creation | 11:03 |
| @sonney2k | SGSparseMatrix<ST> sm=SGSparseMatrix<ST>(NULL, 0, 0, false); | 11:06 |
| @sonney2k | so that is the fix right? | 11:06 |
| blackburn | actually yes | 11:06 |
| blackburn | could be the fix as well | 11:06 |
| @sonney2k | blackburn, the other would require that we use SGSparseMatrix for SparseFeatures (to be put on todo) | 11:07 |
| blackburn | yes, but refcounter = 2 initially would work as well | 11:07 |
| blackburn | however it is a crappy solution :) | 11:07 |

| blackburn | yeah | 11:08 |
| blackburn | I need to hunt for some tea | 11:08 |

| @sonney2k | blackburn, btw same thing holds for pthreads etc | 18:37 |
| @sonney2k | blackburn, can you fix the memory leaks in the libshogun examples? there are quite many... | 18:38 |
