n4nd0sonne|work: hi!09:43
n4nd0I checked how this history of changes for the webpage could be added09:57
n4nd0It looks like this could be a good star: https://bitbucket.org/dwatkinsweb/django-simple-history09:58
n4nd0I reached it from this post: http://stackoverflow.com/questions/987669/tying-in-to-django-admins-model-history09:58

sonne|workn4nd0: hey!10:08
sonne|workn4nd0: looks quite promising10:08
sonne|workn4nd0: is this then already integrated in the admin view somehow?10:08
n4nd0sonne|work: I don't think so10:09
sonne|workI mean what I don't understand is how one can put an old revision live10:09
n4nd0the admin view is customizable10:09
n4nd0so I think the idea would be to use this django-simple-history to automatically create revisions of the articles every time they are updated10:10
n4nd0or created10:10
n4nd0and then modify the admin view as we like to show these old versions10:10
sonne|workn4nd0: ok - the only thing that would not work with this is that we cannot select the version to be shown on the website10:11
sonne|workit would be nice if we just edit10:11
sonne|workand then at some point tag a publish flag10:12
n4nd0sonne|work: aham. Yes, that is an even better idea10:12
n4nd0That could be done adding a new model probably10:13
n4nd0I don't know if it would be the best solution though10:13
sonne|workno idea what is best but certainly adding just an integer for the revision and a boolean flag 'published' would do10:19
sonne|workohh no11:01
sonne|workit is snowing again!11:01
blackburnsonne|work: ha-ha11:03
sonne|workblackburn: btw congrats: http://investors.tomtom.com/releasedetail.cfm?ReleaseID=75422711:06
blackburnsonne|work: oh everybody hates moscow :D11:09
blackburnespecially its citizens11:09
blackburnthey basically live in jams11:09
blackburnsonne|work: one more thing is that it is crazy expensive to live there and people live outside of the city - then they have to say move 2 hours by train and stay 2 hours in jams11:12
blackburnI have absolutely no idea how do they live :D11:12
blackburnbut I know quite a few that live that way11:12
sonne|workdoesn't sound nice..11:17
blackburnsonne|work: but it is believed that there is no life outside moscow so 10% of russia lives there :D11:18
sonne|workhehe11:19
blackburnsonne|work: 20M of 140M totally - crazy isn't it?11:20
sonne|workits big11:23
wikingblackburn: does that mean that we can directly commit to shogun-toolbox/shogun.git?11:23
blackburnwiking: yes I think so11:23
blackburnnot to master though11:23
wikingyeah sure thing11:24
blackburnsonne|work: do you mind commits to develop without branches?11:24
blackburnI don't know if we really should use that hotfix stuff11:24
wikingn4nd0: i saw the emails.. sorry but i'm away atm but i'll answer asap11:24
n4nd0wiking: sure, no problem11:25
n4nd0wiking: I think that he can find what he asked for in the doc of latent svm though11:25
sonne|workblackburn: yes11:25
blackburnsonne|work: yes - use hotfix?11:26
sonne|workthat too yes11:26

heikosonne|nowork, blackburn as I said, I probably need some help. I would be up for creating a howto on this and update on the way11:36
heikolets discuss later, got a huge pile of work lying here :)11:36
blackburnn4nd0: oh we've got vi{c,k}tors11:41
blackburnZeThomas: hey11:43
ZeThomasblackburn: hi11:43
blackburnlet me get back to your thing11:43
blackburnis it still failing?11:43
ZeThomasyes11:43
n4nd0blackburn: hehe yeah :D11:46
blackburnZeThomas: error 139?11:47
ZeThomasindeed11:47
ZeThomashappens in the init step apparently11:49
ZeThomasline 83 in http://pastebin.com/567TrTnx11:49
ZeThomaswithin the init in line 38: sg.DirectorKernel.init(self, l_features, r_features)11:51
ZeThomasI can't dig deeper than that :)11:55
blackburnZeThomas: so 3811:55
ZeThomasyep11:55
blackburnZeThomas: can you please run gdb on it?12:00
ZeThomasok, you might have to talk me through this, how do I gdb a python prog?12:04
blackburnZeThomas: gdb --args python yourscript.py12:04
blackburnthen start12:04
blackburnthen c12:04
ZeThomasok, I get this: http://pastebin.com/4Bc4dfij12:07
blackburnZeThomas: 'back'12:10
ZeThomashttp://pastebin.com/0Dw1msdr12:11
blackburnZeThomas: quite interesting heh12:15
ZeThomasblackburn: I'm not getting very much out of this... :)12:16
blackburnI expect it fails on to->name12:16
ZeThomasyou mean in the typecheck (is that for the (dummy)features?)12:20
blackburnZeThomas: yeah that's crazy12:20
ZeThomascould it be because I have these variables l and r as attributes?12:20
blackburnno shouldnot be12:21
ZeThomas(renamed them all, to no avail)12:22
blackburnohhh12:23
blackburnwhy do you call init(self, l_features, r_features)12:23
blackburnit should be (l_features, r_features) just12:23
blackburnsonne|nowork: another trick of python12:24
blackburnsonne|nowork: method with 2 parameters is called with 3 parameters and no error (??)12:24
blackburn*args, **kwargs probably12:25
blackburnZeThomas: ^12:25
ZeThomasblackburn: because DirectorKernel.init is a method with 3 params12:27
blackburnZeThomas: no thats __init__12:28
blackburnvirtual bool init(CFeatures* l, CFeatures* r)12:28
ZeThomasevery instance of it automatically fills in itself as first argument12:28
ZeThomasno, every class method is like that12:28
blackburnyes I know what you mean but I am not sure it is the case12:28
ZeThomasblackburn: ok yeah, every python class method12:28
blackburnhmm let me think12:29
ZeThomasI don't know how CPython then handles this12:29
blackburnZeThomas: cpython?12:29
ZeThomasblackburn: scrap that last remark12:30
blackburnZeThomas: yes you are right self is needed here12:31
blackburnZeThomas: could you try to name it custom_init or whatever?12:32
blackburnI am worried about name clash12:32
ZeThomasblackburn: I tried this: http://pastebin.com/DsP4ka0z and this works fine12:33
blackburntrue12:33
ZeThomasbut wait12:34
blackburndo you see any difference?12:34
ZeThomasI get this warning with this toy example, which I don't get in the other case12:35
ZeThomasRuntimeWarning: [WARN] Enforcing to use only one thread due to restrictions of directors12:35
blackburnZeThomas: that's ok12:35
ZeThomaswhy is that?12:35
blackburnZeThomas: director kernel can be called only from one thread12:36
ZeThomasyeah, I know, but why is it that in the crashing case I don't get this warning?12:36
blackburnyour code is not getting to that line12:36
blackburnit fails before12:36
ZeThomascould it be because I called init already once, in my __init__ ?12:39
blackburnbut it worked back when?12:40
blackburnthen*12:41
ZeThomasok there's some stupid stuff in there, I don't know why (I think my lacking vim-fu)12:43
ZeThomaslike the real __init__ in another one in the abstract class?12:43
ZeThomasI'm fixing that first12:43
blackburnyou mean that __init__ inside __init__?12:44
ZeThomasyeah, don't really know why that's there...12:45
ZeThomasok, I seems to work now, this was weird12:49
ZeThomastraining that svm seems to take ages though12:51
blackburnthat's strange12:52

blackburnZeThomas: what happened after the first iteration?13:56
ZeThomasthis is the code: http://pastebin.com/F9n3GLTy ; iterations are at line 12313:58
ZeThomasso it must segfault before the second iteration starts, seeing the output13:59
ZeThomashowever, that's not a constant, since the previous time it segfaulted after 2 iterations14:00

ZeThomashaha I just added some print statements to localise, and it gets further than before15:25
ZeThomasgotta love computers15:25
n4nd0ZeThomas: are you using all the time the same data?15:30
ZeThomasn4nd0: it's randomised, but I set a fixed seed for consistency in testing... If I'm not mistaken this takes all 'randomness' away15:31
n4nd0ZeThomas: ok, I think for debuggin you should fix the data15:32
n4nd0otherwise it could be completely fine that the code crashes in different parts for each execution15:32
ZeThomaswell, but that's what setting a seed does, right15:33
n4nd0if I were you, I would ensure it :)15:33
ZeThomasyou're making me curious... checking right now15:35
ZeThomasyep, that's good15:40
n4nd0ZeThomas: is there any randomness anywhere else in your method?15:42
ZeThomasblackburn, n4nd0: it's in the loop at line 87 (this time...); http://pastebin.com/F9n3GLTy15:44
ZeThomasand n4nd0: nope, no randomness, as far as I'm aware15:44
n4nd0ZeThomas: my point is:15:44
ZeThomasthe gdb crash location seems now consistent though with how it was outside of it...15:45
n4nd0if there is no randomness in the input to your program or on the task it does15:45
n4nd0then there must be some invalid memory access15:45
ZeThomasthat's what I was thinking as well15:45
n4nd0since I believe you cannot do this in python, I believe it must be in the C++ code15:46
n4nd0valgrind may help you to find it out15:46
n4nd0but if you are going to valgrind some python program, you better use a suppression file. Otherwise you will see lot of junk15:47
ZeThomasok, this sounds very vague to me15:48
n4nd0hehe ok, sorry15:48
n4nd0ZeThomas: so the data you are using, is it big?15:48
n4nd0you could for example input minimal data15:48
n4nd0print what's going on every few steps on your algorithm15:49
n4nd0and make sure it happens as you expect15:49
ZeThomasok, i'll try that15:55
n4nd0ok gtg now, see you later16:01

blackburnlet me check16:05
blackburn102??16:05
blackburnwhat about deeper?16:05
ZeThomasit's very weird, because with other kernels this part of the code never fails, and is very unrelated to any shogun code16:06

ZeThomaswhich basically constructs a new object, with 3 strings and a tuple as args...16:16

lambdayyes...19:48
heikolambday: this is actually gonna help us a lot :)19:48
lambdayheiko: hmmm... i still haven't checked it..19:49
heikobasically you develop new stuff in feature branches19:49
heikowhich are then committed/merged19:49
heikoand eventually merged into thedevelopment branch19:49
lambdayhmm...19:50
lambdayI need to check this gitflow thing...19:51
n4nd0heiko: btw, we still need to do the PR through github, don't we?19:51
lambdayand in my system, all I need to do is to change the upstream to "features", right?19:51
heikon4nd0: I think yet, but I haven't comitted anything since then19:52
n4nd0heiko: ok19:52
heikolambday, n4nd0 I did not yet have time to check out the details, but check19:52

heikome too :)19:53
lambdayheiko: by the way, on a different topic, for classification using svm, n train and m test points, the train kernel should be nxn, right? then we train the svm, and then we fit the test kernel nxm in it after training, and use it to get labels.. right?19:56
heikolambday:  let me think ...19:58
heikolambday: yes, thats how it works19:58
heikoin shogun we have this lhs rhs thing on the kernel19:58
lambdayheiko: just a sec, be right back19:58
heikolhs is always training, rhs is first training, then test19:58
heikoso exactly training matrix is nxn, test matrix is nxm19:58
