-!- gsomix [~gsomix@] has quit [Read error: Connection reset by peer]19:49
@iglesiasgpickle27: is there any obtain_from_generic method?19:49
@iglesiasgIn the labels it is done with a LabelsFactory or FactoryLabels thing19:50
pickle27hmm I'll look19:50
pickle27there is an obtain_from19:52
pickle27I got an error running it though19:52
pickle27I need the actual matrix back so I can plot19:52
pickle27thats why I need RealFeatures19:53
-!- HeikoS [] has joined #shogun19:55
-!- mode/#shogun [+o HeikoS] by ChanServ19:55
@iglesiasgpickle27: I didn't understand it, sorry19:57
@iglesiasgpickle27: did you manage to build for R btw?20:00
pickle27not yet20:00
pickle27iglesiasg: do you know how I can cast in octave?20:07
pickle27instructions online are only for built in types20:07
@iglesiasgpickle27: let me check20:09
@iglesiasgpickle27: have you taken a look to python examples, maybe there is something similar?20:10
@iglesiasgpickle27: we're interesting in casting Features to RealFeatures right?20:10
pickle27Im am porting my own python example20:10
-!- gsomix [~gsomix@] has joined #shogun20:12
@iglesiasgpickle27: all right, so do you see obtain_from_generic in CMatrixFeatures and CLatentFeatures?20:13
pickle27I don't actually20:15
-!- zxtx [] has joined #shogun20:15
@iglesiasgpickle27: hehe wait a second20:15
pickle27Latent has it20:16
@iglesiasgmaybe I am telling you sth wrong20:16
@iglesiasgMatrix features too20:16
pickle27kk its not in doxygen yet20:17
@iglesiasgpickle27: aaah oh sorry then20:17
@iglesiasgpickle27: I never check doxygen, but the code20:17
@iglesiasgpickle27: so I think you need that sort of method but in CDenseFeatures20:17
pickle27probably a good idea20:17
pickle27yeah I guess so, I wasn't planning on having to do framework mods for this lol20:18
@iglesiasgpickle27: providing we're developers of Shogun yeah, but doc should be updated too. It is what users will want to use20:18
pickle27but you're right thats what I need20:18
@iglesiasgpickle27: I am wondering now20:18
@iglesiasgpickle27: it is missing just because someone didn't need to do that before (which I find odd)20:18
@iglesiasgpickle27: or because there is another way to do it20:18
pickle27in C++ you can just Cast directly its just in octave that it seems like there is no way to do this20:19
pickle27see there is an obtain from dot in DenseFeatures20:20
@iglesiasgpickle27: where?20:21
pickle27line 27620:22
@iglesiasgpickle27: aham! but that is actually doing much stuff20:23
@iglesiasgpickle27: like copying memory and everything20:23
@iglesiasgpickle27: isn't it?20:24
pickle27looks like it20:25
@iglesiasgpickle27: what you need is actually simpler, I think20:25
pickle27this is my cpp example20:26
pickle27I just cast the pointer20:26
pickle27line 8820:26
pickle27and here is python20:26
pickle27line 41, didn't have to do anything20:27
@iglesiasgpickle27: but you are getting trouble in octave_modular trying to do the same thing?20:28
-!- gsomix [~gsomix@] has quit [Ping timeout: 276 seconds]20:29
pickle27yeah because I can't cast my CFeatures to CDenseFeatures in order to call get_feature_matrix20:29
@iglesiasgpickle27: what I mean is that in python you didn't have that problem but you do in octave?20:29
@iglesiasgpickle27: or is it in both because you cannot cast as in C++?20:30
pickle27in Octave I get "error member not found"20:30
pickle27python works great20:30
@iglesiasgpickle27: I guess this is because there is some SWIG code that fixes this for python, but it doesn't for the other interfaces20:30
pickle27its because of python is typed20:33
@iglesiasgpickle27: I am not sure actually why it works in Python but not in octave20:34
@iglesiasgpickle27: what?20:34
pickle27octave can't see that the object is really a densefeatures obj because the pointer is the generic one20:34
pickle27python can see that20:34
pickle27meh I just figured a way to side step this for now20:35
@iglesiasgpickle27: hehe ok20:35
@iglesiasgpickle27: did you read that thing that it works with python but not with octave because the first one is typed and not the other?20:38
pickle27no just kind of a gut instinct from what I know about python and how Im seeing the swig wrapper working with octave20:39
pickle27any idea why my R_modular is crashing?20:39

@iglesiasgpickle27: check tee20:45
