06:27 < chopper_inbound4> Hey Shikhar Jaiswal (Gitter) , are you online? I need some help regarding #2364.
07:36 < jenkins-mlpack2> Yippee, build fixed!
07:36 < jenkins-mlpack2> Project docker mlpack nightly build build #671: FIXED in 3 hr 22 min: http://ci.mlpack.org/job/docker%20mlpack%20nightly%20build/671/

16:43 < marko> hi
16:43 < marko> i cannot save LARS model in CPP
16:44 < marko> here is the code
16:44 < marko> / Declare GLM wh specific parameters.
17:03 < zoq> marko: Don't see any code so far.
17:06 < marko> OK
17:06 < marko> i repeat
17:06 < marko> line by line
17:06 < marko> mlpack::regression::LARS glm(0.25,0.25);
17:06 < marko> can you see now?
17:10 < marko> glm.Train(x_train, y_train, false);
17:11 < marko> mlpack::data::Save("glm.xml","model", glm, false, mlpack::data::format::xml);
17:13 < marko> ?
17:14 < jeffin143[m]> You can share code
17:14 < jeffin143[m]> Using pastebin marko
17:14 < jeffin143[m]> Also you can add comments there to quickly make us understand :)
17:14 < jeffin143[m]> I am guessing the ui here is not good enough
17:15 < marko> OK
17:15 < marko> i try again
17:15 < jeffin143[m]> If you need any help in sharing code let me know
17:15 < marko> mlpack::regression::LARS glm(0.25,0.25);
17:15 < marko> now?
17:15 < zoq> marko: What is the error you get?
17:15 < jeffin143[m]> Yeah it is good :)
17:16 < jeffin143[m]> If you are comfortable we are good
17:16 < marko> glm.Train(x_train, y_train, false);
17:16 < marko> mlpack::data::Save("glm.xml","model", glm, false, mlpack::data::format::xml);
17:17 < marko> that is the whole piece of the code
17:17 < marko> and the build is not sucessful
17:17 < zoq> marko: Okay, do you have error as well?
17:18 < marko> 'serialize': is not a member of 'arma::Mat<double>'
17:18 < zoq> What version are you using?
17:19 < marko> 3.1.1.-1
17:20 < marko> W10; VS2017CE; mlpack is installed via vcpkg
17:24 < marko> any help from the other side?
17:27 < zoq> marko: So bascially like: https://gist.github.com/zoq/66eae78182cc675e2282fcbe664249a2
17:27 < zoq> marko: just did a quick test on lab.mlpack.org and had no issues
17:28 < marko> looking at the doc
17:28 < zoq> marko: can you run the code and see if that works?
17:28 < marko> but save it
17:28 < marko> save the model
17:28 < marko> that is what i cannot do
17:29 < marko> this line fails
17:29 < zoq> https://gist.github.com/zoq/66eae78182cc675e2282fcbe664249a2
17:29 < zoq> like this, works as well
17:30 < marko> mlpack::data::Save("glm.xml","model", glm, false, mlpack::data::format::xml);
17:30 < marko> OK
17:30 < marko> then
17:30 < marko> I will analyze your example
17:30 < marko> and try to understand where is the error
17:30 < marko> in my program
17:30 < rcurtin> marko: I saw you were using 3.1.1; if you can upgrade, perhaps this might help
17:31 < rcurtin> zoq: it is so cool that the notebooks are working now... those gists are awesome :)
17:31 < marko> vcpg does not offer to upgrade
17:31 < marko> i mean
17:31 < marko> it says its all good
17:31 < marko> no newer version
17:31 < rcurtin> weird, they just updated to 3.2.2: https://github.com/microsoft/vcpkg/tree/master/ports/mlpack
17:31 < rcurtin> and we just released 3.3.0
17:31 < zoq> marko: did you include: #include <mlpack/core.hpp>
17:32 < marko> of course...
17:32 < rcurtin> I don't know much about vcpkg though so I can't say why the newer version isn't available. you could always file a bug there? :) or maybe you can get it to work with 3.1.1

17:32 -!- Irssi: #mlpack: Total of 109 nicks [0 ops, 0 halfops, 0 voices, 109 normal]
17:33 < zoq> Does vcpkg ship the executables as well?
17:33 < marko> https://github.com/microsoft/vcpkg
17:35 < zoq> Looks like they do, maybe you can test the lars executable and see if you can save the model?
17:35 < marko> but if I understand
17:35 < marko> from the standpoint of syntax
17:36 < marko> you see nothing wrong with my code
17:36 < marko> ?
17:37 < marko> btw the error resides
17:37 < marko> in this file
17:37 < marko> c:\vcpkg\installed\x64-windows\include\boost\serialization\access.hpp
17:39 < zoq> Looked good to me, couldn't really run it because I don't have the data, but I guess it's pretty similar to what I used for testing?
17:41 < marko> than
17:41 < marko> all the best guys
17:41 < marko> and many, many thanks for help
17:41 < marko> i consider the gist instrucive
17:41 < marko> i will try to go on with debugging
17:49 < marko> btw I live in Augsburg :D
18:11 < rcurtin> =[]'
18:11 < rcurtin> oops, cat keyboard
18:23 < marko> no problem
18:23 < marko> :D
18:23 < zoq> marko: Augsburg, stay safe
18:24 < marko> you ca tell zoq that I have ran the code
18:24 < marko> and the code works
18:24 < marko> his code
18:24 < marko> :(
18:24 < marko> now i need to understand why my code is not working
18:24 < zoq> okay, strange
18:24 < marko> we will do the best
18:24 < marko> pandemic is declining here in Germany
18:24 < marko> thats good news
18:25 < marko> however, we will see what happens after that
18:25 < marko> than it becomes critical
18:25 < zoq> maybe you can post the code on pastbin or github gist, it's a little bit hard to read in irc :)
18:25 < marko> there is really nothing
18:25 < marko> to add
18:25 < marko> except i do not use beta
18:25 < marko> and there is decomposition is false
18:26 < marko> so i need to understand where is the error
18:26 < zoq> marko: That shouldn't change much.
18:26 < marko> because i have the XML with your model
18:26 < marko> i know
18:26 < zoq> okay, but that is good.
18:26 < marko> :(
18:26 < marko> many thanks
18:26 < marko> and keep up the good work
18:27 < marko> signing out
18:27 < zoq> I'm in Berlin, so I'm in a similar situtation.
18:27 < marko> yes
18:27 < marko> i know
18:27 < marko> i have alreaddy starred some of the Github repositories
18:27 < marko> that you have
18:27 < zoq> marko: :)
18:27 < marko> good work
18:27 < marko> impressive work
18:28 < marko> to be exact
18:28 < marko> im data scientist at MAN btw
18:28 < marko> so we might push a little bit more with this CPP thing
18:28 < zoq> Great, hopefullt mlpack can be of any help :)
18:28 < marko> its good environment for ML
18:29 < marko> maybe better than Java
18:29 < marko> we will se
18:29 < zoq> Right, I guess python is strong too.
18:29 < marko> there is slightly more emphasis on classification tasks
18:29 < marko> I would say that regression tasks are underrepresented in MLPack
18:29 < marko> but it is still solid
18:31 < zoq> The field is so broad it's tricky to keep up.
18:31 < jeffin143[m]> And it also grows
18:31 < jeffin143[m]> So consuming it becomes
18:31 < jeffin143[m]> More difficult
18:32 < jeffin143[m]> Each day they is some new things Ppppin
18:32 < jeffin143[m]> Popping up
18:32 < jeffin143[m]> I have made a list to read those and it has only grew , can't keep even track of it
18:35 < marko> its important that there is progress
18:35 < marko> keep up the good work
18:35 < marko> we keep in touch
18:35 < marko> regards
18:35 < zoq> see you around
