| uzunov | hi there - I am getting a strange error when running the shogun toolkit through the R modular interface. The toolkit and the interface seemed to compile without issue, but then when I run one of the test examples(mkl_multiclass_modular.R), I get the following error on the very last line of the script (out <- lab$get_labels()) | 01:33 |

| uzunov | Anyone have an idea of what might be wrong? Maybe I did not install something properly? The rest of the script runs fine though. Any help is greatly appreaciated. | 01:35 |

| Saurabh7 | hey iglesiasg | 07:34 |
| @iglesiasg | hey Saurabh7 | 07:34 |
| Saurabh7 | iglesiasg, i am having issues with the mailing list | 07:35 |
| @iglesiasg | Saurabh7, tell me, what issues? | 07:35 |
| Saurabh7 | not recieving mails even though i am subscribed | 07:35 |
| Saurabh7 | iglesiasg, i even tried setting the options again | 07:35 |
| @iglesiasg | Saurabh7, mmm, that's weird | 07:35 |
| @iglesiasg | Saurabh7, so, you didn't receive any of the GSoC updates? | 07:36 |
| Saurabh7 | iglesiasg, no | 07:36 |
| @iglesiasg | Saurabh7, let me check for your user in the list of subscribers | 07:36 |
| Saurabh7 | iglesiasg, i ended double posting too on new thread | 07:36 |
| @iglesiasg | Saurabh7, yeah, I saw that | 07:36 |
| Saurabh7 | iglesiasg, thats because didnt recieve the first thread | 07:37 |
| Saurabh7 | iglesiasg, and even the archives didn't show that on gmane | 07:37 |
| @iglesiasg | Saurabh7, well, they do show now. Maybe there is just a delay in the archives? | 07:38 |
| Saurabh7 | iglesiasg, yes but shouldn't i be recieving the mails? | 07:38 |
| Saurabh7 | iglesiasg, i didn't get the meet up one too | 07:39 |
| Saurabh7 | iglesiasg, i don't want to miss something else | 07:39 |
| @iglesiasg | Saurabh7, what address did you use to subscribe? | 07:40 |
| kislay | iglesiasg, me too. I never received a single mail till now. I keep checking the archives everyday.. | 07:40 |
| Saurabh7 | iglesiasg, my email : saurabh.mahindre@gmail.com | 07:40 |
| @iglesiasg | I see you are subscribed with this one | 07:41 |
| @iglesiasg | saurabh.mahindre@gmail.com | 07:41 |
| @iglesiasg | the spelling looks correct | 07:41 |
| Saurabh7 | iglesiasg, there seems to be some issue then | 07:41 |
| @iglesiasg | you have a checkbox called ack with a tick, you seem to be the only one who has it | 07:41 |
| Saurabh7 | err, what might that be ?! | 07:42 |
| @iglesiasg | Saurabh7, but I guess that is that you get an automatic response once you publish? | 07:42 |
| Saurabh7 | iglesiasg, nope nothing, weird enough i don't get anything | 07:43 |
| Saurabh7 | kislay, is also not getting it seems | 07:43 |
| @iglesiasg | Saurabh7, just in case -- I guess you checked already your spam folder | 07:44 |
| Saurabh7 | iglesiasg, yup checked, no spam, no filters | 07:45 |
| @iglesiasg | Saurabh7, you have the digest mode on as well | 07:47 |
| @iglesiasg | Saurabh7, that would explain that you don't get every single mail once it is sent | 07:47 |
| @iglesiasg | Saurabh7, but you should get a collection of them at least daily | 07:47 |
| Saurabh7 | iglesiasg, nothing from the list so far , not even 1 mail | 07:48 |
| kislay | same here. | 07:48 |
| Saurabh7 | iglesiasg, hope i am not irritating you :) | 07:48 |
| @iglesiasg | Saurabh7, it's ok | 07:48 |
| Saurabh7 | iglesiasg, just wanted to inform you about it, maybe we can find a fix | 07:50 |
| @iglesiasg | kislay, what's the mail you subscribed with? | 07:51 |
| @iglesiasg | kislay, abhijeet.kislay.eee11@itbhu.ac.in? | 07:51 |
| kislay | iglesiasg, yup | 07:52 |
| kislay | iglesiasg, exactly! | 07:52 |
| @iglesiasg | kislay, this is the one you are subscribed with | 07:52 |
| @iglesiasg | kislay, abhijeet.kislay.eee11@itbhu.ac.in | 07:52 |
| @iglesiasg | kislay, the spelling looks all right to me, but please double check | 07:52 |
| kislay | its correct | 07:53 |
| @iglesiasg | kislay, ok you also had the digest mode on | 07:53 |
| @iglesiasg | kislay, Saurabh7, so it might be related to this | 07:53 |
| kislay | iglesiasg, but no mails so for | 07:53 |
| @iglesiasg | kislay, Saurabh7, I just turned off the digest mode for both of you | 07:53 |
| @iglesiasg | let me send a test mail to the mailing list and hope you guys will get | 07:53 |
| kislay | yeah! | 07:54 |
| Saurabh7 | ok , ! | 07:54 |
| @iglesiasg | Saurabh7, kislay let me know please | 07:55 |
| Saurabh7 | iglesiasg, got it! | 07:56 |
| Saurabh7 | great! | 07:56 |
| kislay | iglesiasg, awesome. got it | 07:57 |
| Saurabh7 | iglesiasg, thanks for fixing it, and sorry for double posting :) | 07:58 |
| @iglesiasg | happy to hear it is fixed now :) | 07:59 |

| khalednasr | lambday, hey | 17:09 |
| lambday | khalednasr: hey | 17:09 |
| lambday | khalednasr: how's it going? | 17:10 |
| khalednasr | lambday, good, you? | 17:10 |
| lambday | khalednasr: just started with vector-sum thingi | 17:11 |
| lambday | khalednasr: you know if there's a method in viennacl that computes sums of values? | 17:11 |
| lambday | sum of all elements in vector I mean | 17:11 |
| khalednasr | lambday, nope, they don't have a method for that :( | 17:12 |
| lambday | khalednasr: I was afraid so... found till hell without any luck | 17:12 |
| lambday | I'm using std::accumulate | 17:12 |
| khalednasr | so you copy stuff back to the cpu? | 17:13 |
| lambday | khalednasr: umm.. not sure what to do.. may be you have an idea? this won't work when vector loaded on gpu? | 17:14 |
| khalednasr | lambday, it can be done with an custom opencl kernel | 17:15 |
| lambday | khalednasr: alright! that's something I don't have any idea - | 17:16 |
| lambday | khalednasr: so I'm just adding eigen3 here... may be you can add viennacl version when you have time/when you'll need it? | 17:16 |
| khalednasr | lambday, yeah, I'm gonna need to implement it later on anyway | 17:16 |
| lambday | khalednasr: cool! | 17:16 |
| khalednasr | lambday, there's a problem that I ran into when I tried to do what we talked about last time | 17:17 |
| khalednasr | lambday, https://gist.github.com/khalednasr/ae85d6d13fbe572e2bdc | 17:17 |
| lambday | khalednasr: what is it? | 17:17 |
| khalednasr | lambday, some compile error that I can't figure out | 17:18 |
| lambday | khalednasr: checking | 17:18 |
| lambday | khalednasr: argh - this is because in the specialization we're using a matrix type that cannot be matched with the generic one | 17:19 |
| lambday | extra 2nd template arg - | 17:19 |
| lambday | crap man | 17:19 |
| khalednasr | it compiles as long as you don't try to call the function | 17:20 |
| lambday | khalednasr: the only way I can imaigne is to use a proxy type | 17:21 |
| lambday | really! | 17:21 |
| lambday | may be because some crazy compiler optimization thing | 17:21 |
| khalednasr | lambday, that's why I thought it worked, when we talked last time | 17:22 |
| lambday | khalednasr: ah I see | 17:22 |
| lambday | khalednasr: let me play with this a bit | 17:22 |
| khalednasr | lambday, have fun :) | 17:22 |
| lambday | khalednasr: but unless we use a fake type I don't see any other way we can handle it | 17:23 |
| khalednasr | lambday, yeah probably | 17:23 |
| khalednasr | lambday, we could write a SGMatrix-style wrapper around it | 17:23 |
| lambday | khalednasr: no but wait! I misunderstood something | 17:24 |
| lambday | this *should* work | 17:24 |
| lambday | you're using VCLMatrix | 17:24 |
| lambday | which has 2 template args | 17:25 |
| khalednasr | yup | 17:25 |
| lisitsyn | heyy | 17:28 |
| khalednasr | hey | 17:29 |
| khalednasr | lisitsyn, the gpu stuff is gonna take more time than I thought it would.. | 17:30 |
| lisitsyn | khalednasr: that's ok deadlines are for n00bs :D | 17:31 |
| lisitsyn | khalednasr: what's in particular causing struggles? | 17:31 |
| khalednasr | lisitsyn, :D | 17:31 |
| khalednasr | lisitsyn, viennacl matrices don't fit with the linalg library | 17:32 |
| khalednasr | lisitsyn, they have different template arguments than SGMatrix and eigen3 matrix | 17:32 |
| lisitsyn | different like? | 17:33 |
| lisitsyn | khalednasr: ahh you mean they have different number of template arguments? | 17:33 |
| khalednasr | template <class T, class F, unsigned int> | 17:33 |
| lisitsyn | what's F for btw? | 17:34 |
| khalednasr | row major vs column major | 17:34 |
| lisitsyn | erhrr | 17:34 |
| lisitsyn | I see | 17:34 |
| lambday | lisitsyn: we managed this thing for vector with template <class Info, template<class,Info...> class Vector, class T, Info... info> if you remember | 17:34 |
| lisitsyn | lambday: yeah | 17:34 |
| lambday | lisitsyn: this fails for matrix for their f**king different template args for matrices :( | 17:35 |
| lambday | lisitsyn: so khalednasr suggested that we should have two versions for row-majors and col-majors and fix the type | 17:35 |
| lisitsyn | like a wrapper | 17:36 |
| lisitsyn | that fixes the value | 17:36 |
| lisitsyn | e.g. as row major | 17:36 |
| lisitsyn | ? | 17:36 |
| khalednasr | lisitsyn, yup, https://gist.github.com/khalednasr/ae85d6d13fbe572e2bdc | 17:36 |
| lambday | lisitsyn: pretty much | 17:36 |
| lisitsyn | ah these template aliases | 17:37 |
| lisitsyn | I barely understand consequencies but it looks ok | 17:38 |
| lisitsyn | do you see any drawbacks? | 17:38 |
| khalednasr | except that it doesn't work when you try to call the method :D | 17:38 |
| khalednasr | it compiles as long as you don't try to use it | 17:38 |
| lisitsyn | hahah | 17:38 |
| khalednasr | lisitsyn, anyway, I started working on conv. nets, in parallel with the gpu stuff | 17:40 |
| khalednasr | lisitsyn, gonna send a PR with some basic methods later today | 17:40 |
| lisitsyn | khalednasr: yeah sounds good | 17:40 |
| lisitsyn | khalednasr: lambday: I could try to come online a bit later to discuss it a bit more | 17:41 |
| lisitsyn | may be we could come up with some solution | 17:41 |
| lambday | lisitsyn: yep! since linalg is in its infancy, its easier for now to change things | 17:41 |
