@iglesiasgHello nileshK, how are you doing?09:57
nileshKHi10:01
nileshKI am good10:01
@iglesiasgCool, good to hear10:01
@iglesiasgLet's try to get your issue sorted out. Did you get to a new point?10:02
nileshKYeah I have reached here10:02
nileshKHavent done the fix yet.10:03
nileshKhttps://www.irccloud.com/pastebin/20bI0Zyf10:03
nileshKAlso I tried moving it to the LPM.cpp10:03
@iglesiasgAll right, let's try then if the last fix I told you fixes that10:04
@iglesiasgMoving CLMP::set_features to LPM.cpp and also including DotFeatures.h there10:04
@iglesiasgerr, CLPM::set_features, sorry10:04
nileshKYeah. Let me do that. And I have a a bad internet connection10:07
@iglesiasgThat's ok10:07
@lisitsynhey10:08
@iglesiasghello10:08
@lisitsynhow are you?10:08
@iglesiasggood good, and you?10:09
@lisitsyna bit sick, Heiko sent me some viruses I guess10:09
@lisitsyn:D10:09
nileshKHaha10:09
@iglesiasghaha10:09
@lisitsynwhat's the LPM thing going on? are you working on something?10:09
nileshKFernando: It went through waiting for it to throw some error 7 % till now10:10
nileshKWe are actually trying to get Cplex parts of the code working. They havent been updated since long10:11
@lisitsynahh10:11
@lisitsyndrop them10:11
nileshKSo, LPBoost LPM this algorithms had stopped working10:11
@lisitsyn:D10:11
nileshKYeah. But as a fact this is one of the USP of Shogun10:12
nileshKThere are no other machine learning libraries that have LpBoost and LPM such algorithms in them10:12
@iglesiasglol10:13
nileshKFernando : new error10:13

@iglesiasgthat a user has to tell us we should not drop something because it is one of our unique features is definitely funny10:13
@lisitsynare they of any use nowadays?10:13
@lisitsyn:D10:13
@lisitsyneverybody just puts a neural layer on top of neural layer nowadays10:14
@iglesiasgI guess the hype has a lot to do with the fact that we only hear about that10:14
nileshKyeah.10:15
@iglesiasgnileshK: there is something weird there10:15
@iglesiasgnileshK: I find no call to get_transposed in that example10:16
nileshKyeah I think I should do a make clean10:16
nileshKand do a make again10:16
@iglesiasgnileshK: oh yeah, please do10:17
@iglesiasgnileshK: by the way10:17
@iglesiasgsince you are compiling and recompiling quite often, ccache will probably be of lot of use10:17
@iglesiasgjust do apt-get install ccache10:17
@iglesiasgand that's all you have to do10:17
@iglesiasgnothing else to take advantage of it whatsoever10:18
nileshKOk10:18
nileshKIt will take 2-3 mins to compile again10:19
@iglesiasgPerfect10:20

nileshKIts taking longer. Will ping you as soon as it gets over10:29
@iglesiasgnileshK: Sure10:30
nileshKhttps://www.irccloud.com/pastebin/LblCTO2K10:33
nileshKStill have the same error iglesiasg10:33
@iglesiasgnileshK: what the heck10:34
@iglesiasgnileshK: please copy the example you have locally and let me see10:34
@iglesiasgnileshK: you can find it under <your_shogun_root_dir>/examples/undocumented/libshogun/balanced...10:34
nileshKIt too does not have any calls to the function get_transposed10:36
nileshKhttps://www.irccloud.com/pastebin/S5Wx3Wqn10:36
@iglesiasgnileshK: all right, then, I think it should be that something that is being used from that example is calling get_transposed(int, int)10:38
@iglesiasgnileshK: let me find out10:38
@iglesiasgthat method indeed exists in CSparseFeatures though...10:39
nileshKHashedWDFeaturesTransposed10:40
nileshKand LPBoost.cpp                init         49 sfeat= ((CSparseFeatures<float64_t>*)10:40
nileshK                                             features)->get_transposed(num_sfeat,10:40
nileshK                                             num_svec);10:40
@iglesiasgnileshK: I think you are building Shogun in Release mode, right?10:40
nileshKare the only two library functions that call get_transposed10:40
nileshKI am not sure.10:41
nileshKI configured it using cmake ../10:41
nileshKno other options10:41
@iglesiasgnileshK: hold on a second10:43
@iglesiasgnileshK: features/SparseFeatures.h:205:CSparseFeatures<ST>* get_transposed(); features/SparseFeatures.h:218:SGSparseVector<ST>* get_transposed(int32_t &num_feat, int32_t &num_vec); features/SparseFeatures.cpp:220:template<class ST> CSparseFeatures<ST>* CSparseFeatures<ST>::get_transposed() features/SparseFeatures.cpp:225:return new CSparseFeatures<ST>(sparse_feature_matrix.get_transposed());10:43
@iglesiasgups, shitty copy paste10:44
@iglesiasghttp://pastebin.com/VXNcTWuh10:45
@iglesiasgSo, basically, the method is only in the header, not implemented...10:45
nileshKoh. I see10:46
@iglesiasgand it is being used in classifier/LPBoost.cpp:49 and mathematics/Cplex.cpp:40110:47
nileshKYeah10:47
@iglesiasgI have to think how to fix this properly, give me some time10:50
nileshKOk10:52
@iglesiasgall right, we are somewhat good10:54
@iglesiasgI have found a commit with the implementation of the method10:54
@iglesiasghttps://github.com/shogun-toolbox/shogun/commit/4e58cf6bec09eb12012f8f77ac6b76441ec8c73410:55
@iglesiasgline 41310:55
@iglesiasglet me see if I find the commit that removed it, there may be a good reason why that was done10:55
@iglesiasgso nileshK11:00
@iglesiasgI am sorry but I need to change plans11:00
@iglesiasgI am at job and I should focus on another thing that would be good to be ready before 3 hours11:00
@iglesiasgyou can continue to investigate this issue a bit further and let me know if you find something out11:00
@iglesiasgI will be back to it later11:01
nileshKOk11:05
nileshKSure :)11:05
nileshKThanks11:05
nileshKI will try to use the implemented method and see if that stuff compiles11:07

nileshKiglesiasg: This was the last commit where the code for get_transposed existed a633ff6f4d9fd9a7672144bee73bc1c5e52938bb11:37
nileshKAnd in the next commit it was removed by Soeren11:38
@HeikoSiglesiasg: parteeey! :)11:43
@HeikoSiglesiasg: havent seen you in ages man, how are things?11:43
nileshKHeikoS: Need a small help11:46
@HeikoSnileshK: hi sure11:47
@HeikoSwhat is it?11:47
nileshKCheck this commit on a633ff6f4d9fd9a7672144bee73bc1c5e52938bb11:47
nileshKIt has a function called get_transposed(int& , int &)11:47
nileshKin SparseFeatures.cpp file11:48
nileshKBut in the next commit the function was deleted11:48
nileshKI am unable to understand the reason for the same11:49
nileshKBecause that function definition was needed for Cplex.cpp and LPBoost.cpp11:49
nileshKHeikoS: I just checked the commits for src/shogun/features/SparseFeatures.cpp11:53

@HeikoShad a meeting16:21

@HeikoSnileshK: It wasnt remove, just changed signature16:31
@HeikoSand since tests doesnt cover cplex, it slipped through16:31
@HeikoSyou can easifly fix this, have a look at the get_transposed method in CSparseFeatures16:31
@HeikoSyou can just adapt the call in LPBoost16:31
@HeikoSone line change16:31
@HeikoSlet us know if you can get it to wokr16:31
@HeikoSand a unit test would also be appreciated16:32
