miniyouHi! I'm using cygwin and can't import modshogun in python. modshogun.py crashes on line 28, in swig_import_helper, on imp.load_module(). I have recreated the error manually: the file is found by imp.find_module(), but can't load it with an "ImportError: No such file or directory". Anyone seen something like this?  http://pastebin.com/6rtYcU4s09:17
miniyou(Disregard lines 6-9 in the paste.) Also, a different question: where should cygshogun-17.dll be placed? After installing, it was only found in build/src/shogun directory. Copying it to current folder allows me to run the examples, but not placing it for example in shogun-install/lib. I've added that folder to LD_LIBRARY_PATH as instructed on https://github.com/shogun-toolbox/shogun/wiki/QUICKSTART09:26
@lisitsynminiyou: not sure about the first question09:30
@lisitsynbut the second is simple09:30
@lisitsynthis .dll should be in whatever folder your system path includes09:31
@lisitsynin linux it would be like /usr/lib09:31
miniyouYeah, that fixed the second question (I misread the path).09:34
-!- kshitijk [~kshitijk@115.249.18.25] has quit [Ping timeout: 256 seconds]09:40
miniyouSolved it!10:00
miniyouMy hypothesis: I thought the "ImportError: No such file or directory" referred to not being able to load _modshogun.dll (even though there was an open filehandle to it!), but it was actually _modshogun.dll that was unable to load cygshogyn-17.dll10:02
miniyouBefore it was in a proper PATH dir10:03
-!- lambday [c40f106c@gateway/web/freenode/ip.196.15.16.108] has quit [Ping timeout: 246 seconds]10:03
miniyouIf that's the case I wouldn't have had the problem if cygshogun-17.dll had been placed in e.g. /usr/bin during install. Anyway, I was able to build and install in less than two days, nice! ;)10:07
@lisitsynminiyou: I am sorry you had to spend that much time :)10:17
@lisitsynglad to hear it is solved10:18

@lambdayHeikoS: lisitsyn: hi12:15
@lisitsynlambday: hey12:15
@HeikoSlambday: hi12:16
@lambdaylisitsyn: I support HeikoS's "ML only GSoC next year"12:16
@HeikoShow are things?12:16
@lisitsynlambday: sure12:16
-!- Bluenotebook__ [~Bluenoteb@122.167.104.146] has joined #shogun12:16
@HeikoSlambday: haha :) lets hope we can prepare ground for it12:16
-!- Bluenotebook__ [~Bluenoteb@122.167.104.146] has quit [Read error: Connection reset by peer]12:16
@lambdaylisitsyn: HeikoS: 1. installation issues 2. tutorial 3. refactoring shogun12:16
@lambdayabout 3, we have plugin projects12:17
@HeikoSlambday: yeah these are all good12:19
@HeikoSif we have those things (and BSD) I also can get funding for hackathon12:19
@HeikoSand we can attract more people12:19
@HeikoSJust wonder who can do the installation issues12:19
@HeikoS.....12:19
@HeikoSbecause we kind of fail :)12:19
@lambdaywiking:12:19
@lambdayHeikoS: what do you mean by BSD? entire shogun under BSD instead of what we currently have?12:20
@HeikoSyes12:21
@HeikoSlambday: we have this12:21
@HeikoSlambday:  see pm12:21
@HeikoSlist of who signed to agree on BSD change12:21
@lambdayhmm12:23
@lambdayI think plugin way is the way to go for futuristic shogun..12:25
@lambdaywe have to figure out a shogun core12:25
@lambdayand shogun apps or shogun extensions12:26
@lambdayfeature, kernel machine classifier etc go to core12:26
@lambdaymore sophisticated parts reside outside12:26
@lambdaythis closely relates to the detox idea we have12:27

@lisitsynHeikoS: !13:54
@lisitsynmachine learning Q13:54
@lisitsynHeikoS: how bad is PCA trained on say 2% of huge dataset?13:56
@lisitsynI have a feeling that's pretty ok but I am not sure..13:57

@HeikoSlisitsyn: hey14:54
@HeikoSlisitsyn: that depends on the dataset14:55
@HeikoSwhat you could do is to run for increasing sizes and check whether solution stabilises, if it does, then you can probably get away with it14:55
@lisitsynHeikoS: I am thinking about making tapkee streaming16:07
@lisitsyn:)16:07
@lisitsynHeikoS: cool idea to check whether it stabilizes..16:08
@HeikoSlisitsyn: check my arxiv paper16:11
@HeikoSits on that topic16:11
@HeikoShow to correct for the error that one gets when doing the stabilisation trick16:11
@HeikoSand what to do if it doesnt stabilise16:11
@lisitsynHeikoS: 2013?16:12
@HeikoS201416:15
@HeikoSunbiased big bayes16:15
@HeikoSthere are lots of plots where I did this for some models16:15
@HeikoSand then do something even better ;)16:15
@lisitsynok thanks I'll print it right now ;)16:15
@lisitsynunderground reading16:15
@lisitsynHeikoS: btw people love command line data tools16:17
@HeikoSlisitsyn: its easy to build them using shogun ;)16:17
@lisitsynHeikoS: tapkee was like header library for me but apparently it's sample (sic!) command line interface is used16:18
@HeikoSWe can provide such tools in shogun too16:28
@HeikoSbut thats kind of not the point16:28
@HeikoSI mean it would be good16:28
@HeikoSif we could maintain it ;)16:28
