sanujbzdmgz, there?14:13
bzdmgzsanuj: FINALLY yes14:15
bzdmgzjust fixed some crazy thing14:15
sanuj:D14:15
sanujhaha14:15
sanujbzdmgz, office work on weekend?14:15
bzdmgzno but fixing it14:15
bzdmgzcrazily out of SLA14:15
sanujhmm14:15
bzdmgzok seen your mail14:16
bzdmgzlet me check14:16
sanujbzdmgz, https://github.com/shogun-toolbox/shogun/pull/3357#issuecomment-23136144014:16
sanujcool14:16
bzdmgzI agree with heiko but we need to separare those14:17
bzdmgzI mean we need that list14:17
bzdmgzbut we can't combine list and create14:17
bzdmgzSO14:17
bzdmgzwhat about removing swig part YET14:17
sanujokay14:17
bzdmgzwe tried, it works14:17
bzdmgzlet me put that so heiko knows14:18
sanujbzdmgz, i'll remove swig from create() and update the PR14:18
bzdmgzyeah tanks14:18
bzdmgzthanks14:19
sanujbzdmgz, see the other PR also14:19
bzdmgzsanuj: yeah14:19
bzdmgzsanuj: actually creating14:19
bzdmgzlike clone14:19
bzdmgzand equals14:19
bzdmgzmaybe it makes sense?14:19
sanujbzdmgz, are you talking about jinja?14:20
bzdmgzyeah14:20
bzdmgzsanuj: I tend to think it makes sense14:20
sanuji've done like the jinja generated unit-tests only14:20
bzdmgzwhat do you think?14:20
sanujyes14:20
sanujjinja is good14:20
bzdmgzno I mean14:20
bzdmgzjust copy what happens in14:20
bzdmgzclone unit test14:20
bzdmgzto test all the clasess are created14:21
sanujI see14:21
sanujbzdmgz, but we need to decide what classes to add14:21
bzdmgzthe only thing bothers me14:21
bzdmgzis that you use14:21
bzdmgzcreate<CKernel>14:21
bzdmgzok they all have base class14:21
bzdmgzjust use create<CSGObject>14:22
sanujbzdmgz, see my updated MockObject14:22
sanuji have created a pointer of CKernel* there14:22
bzdmgzwhere where14:22
sanujin the jinja pr14:22
bzdmgzok let me check14:23
bzdmgzsanuj: oh that looks cool14:26
sanujbzdmgz, the PR?14:26
bzdmgzyeah14:26
sanujthanks14:26
bzdmgzjinja thing look fancy14:26
sanujhaha14:27
sanujbzdmgz, R is failing14:27
bzdmgzyeah14:27
sanujdid you see my last comment14:27
bzdmgznot sure14:27
bzdmgzI think it just doesn't support overloading?14:27
bzdmgzor?14:27
bzdmgzsanuj: we need a patch to disable it for R then14:27
sanujbzdmgz, does anyone use shogun in R?14:28
bzdmgzdoes anyone use shogun14:28
bzdmgz:D :D JK14:28
sanuj:D14:28
bzdmgzsanuj: no idea14:28
bzdmgzwe do not track that14:28
bzdmgzshould intergrate some spyware14:28
bzdmgz!14:28
bzdmgzsanuj: just ignore it do not let it stop you :D14:29
bzdmgzI mean some #ifdef maybe14:29
sanuji see14:29
bzdmgzyou can find some examples actually14:29
bzdmgzin our .i files14:29
sanujthe error happens because of this line in modshogun.R14:29
sanujvaccessors = c('io', 'parallel', 'version', 'm_parameters', 'm_model_selection_parameters', 'm_gradient_parameters', 'm_hash', 'get''get''get''get''get''get''get''get');14:29
sanujthe 'get' madness14:29
sanujbzdmgz, some similar issues were reported by14:30
sanujhttps://sourceforge.net/p/swig/mailman/message/35071142/14:30
sanujhttps://github.com/swig/swig/issues/69714:30
bzdmgzyeah I've seen14:31
sanujcool14:31
bzdmgzshit happens so we have to avoid that14:31
sanujokay14:31
sanujbzdmgz, so no tags-swig for R?14:31
sanujwill use ifdef as you suggested14:31
bzdmgzyeah14:31
bzdmgzunless it is fixed in swig14:31
sanujbzdmgz, i think will take time14:31
sanujif they fix it14:32
bzdmgzyes14:32
bzdmgzlets just wait14:32
bzdmgzonce fixed we enable it for R14:32
sanujokay14:32
sanujbzdmgz, look at this https://github.com/shogun-toolbox/shogun/pull/3357/files#diff-5cdc2a59820a53342121f311fbbe4d51R2614:32
sanujif i use CGaussianKernel* instead14:33
sanujit gives error from because the type are not same as i use setKernel() which expects a CKernel*14:34
bzdmgzshouldnt be casted?14:35
sanujbzdmgz, will try casting14:35
bzdmgzno I mean implicitly14:35
sanujno14:36
bzdmgzwhy?14:36
sanujbzdmgz, well if it was implicitly casted, then it would have worked14:36
bzdmgzyeahh14:37
bzdmgzstrange14:37
sanujbzdmgz, if we do this....is there a problem?14:37
bzdmgzI am not sure what's the problem14:37
bzdmgz:)14:37
sanujcool :D14:38
sanuji was just confirming14:38
sanujbzdmgz, i can't add classes till we decide what classes to add14:38
bzdmgzyeah14:39
sanujbzdmgz, so what are the next steps for tags14:39
sanujand for plugins14:39
sanuji'll update the create PR14:39
bzdmgzsanuj: ok it is hard to decide what classes14:40
sanujand the jinja PR to handle R error14:40
bzdmgzsanuj: what about selecting just a few14:40
sanujbzdmgz, yes14:40
bzdmgzjust to make the simplest complete example work14:40
bzdmgzclassification with kernel svm14:40
sanujbzdmgz, okay14:40
bzdmgzwhole thing should be created by create14:40
bzdmgzno `new` involved14:41
sanujbzdmgz, i will have to change internals of classes to support tag-parameters14:41
sanujbzdmgz, are you talking about using tag-parameters for kernel svm classification example?14:42
sanujor just create?14:42
bzdmgzsanuj: I think tag is tougher14:45
bzdmgzjust create firt14:45
bzdmgzfirst14:45
sanujbzdmgz, so i think the bottleneck is to decide what classes to add for tags14:45
sanujbzdmgz, and it is better if you and heiko do it14:46
bzdmgzit is nearly impossible14:46
bzdmgzwe can start with something and iterate14:46
sanujbzdmgz, okay so what is the next step for the tags PR after i fix R issues14:47
bzdmgzsanuj: I have to think about it14:47
bzdmgzthere are quite a few things to do14:47
bzdmgznot sure how to decompose14:47
bzdmgzbut it is moving quite good14:48
bzdmgzwe will have something fancy quite soon14:48
sanujokay14:48
sanujbzdmgz, next thing for plugins, after i have the svm example ready with create()14:48
bzdmgzsanuj: dlopen thing is due I guess14:49
sanujjust asking this now.....because i don't know when you will be available on irc next :D14:49
bzdmgzhahah14:49
bzdmgzok14:49
sanujbzdmgz, so migrate aer code in shogun14:49
bzdmgzI will try to follow up next week14:49
bzdmgzthis week was crazy14:49
sanujhaha i see14:49
bzdmgzsanuj: so the basic idea14:50
bzdmgzas you have create by string14:50
bzdmgzmake it able to call some library14:50
bzdmgzto ask it to create this object14:50
sanujbzdmgz, so it is like using create with your aer plugin code14:51
sanuji'll have to modify create again then14:51
bzdmgzyeah14:51
bzdmgzbut inside of create14:51
bzdmgzno interface involved14:51
sanujbzdmgz, what interface?14:52
bzdmgzof this 'create' function14:52
sanujabstract class14:52
bzdmgzI mean from user experience it is still create14:52
bzdmgzthe only difference is how we load it14:52
sanuji see14:52
sanujso from user point of view, create() doesn't change14:52
bzdmgzyeah14:52
sanujonly it's internal implementation changes14:53
bzdmgzyeap14:53
sanujbzdmgz, so i'll first make this create svm example work14:53
sanujbzdmgz, and migrate your aer plugin code on a different branch14:53
bzdmgzyes makes sense14:53
sanujand make it work with create()14:53
bzdmgzyeap14:54
sanujbzdmgz, but for this i think i would also need to write a plugin14:54
sanujdummy plugin14:54
bzdmgzyes14:54
bzdmgz:)14:54
bzdmgzgaussian kerel14:54
bzdmgze.g.14:54
sanujbzdmgz, so what's the point of merging create in develop right now?14:55
bzdmgzdid I say that?14:56
bzdmgzoops14:56
bzdmgz:D14:56
sanujokay, not merging then?14:56
bzdmgzI think it can go to tags14:56
sanujhaha14:56
sanujyeah14:57
sanujbzdmgz, will send a pr to tags14:57
