00:57 -!- gitter_jacob-ear [gitterj_37@gateway/shell/matrix.org/x-roqnxfmuaeqwvynt] has joined #mlpack
00:57 -!- gitter_jacob-ear is now known as jacob-earleGitte
00:57 < jacob-earleGitte> I updated to Python 3.8 today and noticed that pip couldn't install mlpack. It did work with older versions though. When will the Python 3.8 compatible package be posted on pypi.org?
03:13 < rcurtin> jacob-earleGitte: hang on a second, I can make that happen as soon as it's built... :) just gotta modify a config setting
03:15 < GauravSinghGitte> Hey @jeffin143 @kartikdutt18 @prince776 Sorry the pull request that I created got deleted because of some mishap from my side. Will create a new PR in an hour. Sorry.
03:15 < rcurtin> https://github.com/mlpack/mlpack-wheels/commit/3a1cee546e828b4ec7e5ac63852881093a9616e9
03:15 < rcurtin> now building at https://travis-ci.org/mlpack/mlpack-wheels, hopefully I will not have some awful thing to debug :)
03:33 < RohitKartikGitte> usually how long does this build take?
03:39 < rcurtin> a couple hours or so, I think?
03:39 < rcurtin> also, sorry about the windows build failures---this was due to a slight server misconfiguration on masterblaster.mlpack.org. I've got that fixed now, so I've restarted many of the PR builds
03:41 < RohitKartikGitte> whats the main focus of "Application of ANN Algorithms Implemented in mlpack", to help new users get familiar and witness the power of mlpack right?
03:47 * RohitKartikGitte sent a long message: < https://matrix.org/_matrix/media/r0/download/matrix.org/mDiXGYkINaxzDqrqIelretaY >
03:47 < RohitKartikGitte> does this sound like something you would like me to work on this summer?
03:53 < kartikdutt18Gitt> @gaurav-singh1998, no worries.
04:12 < simplesit[m]> whoa, this place is really active!
04:20 < RohitKartikGitte> Welcome to the community :)
04:59 < TanayMehtaGitter> @OO7kartik The idea seems great! Do you happen have knowledge of any good visualization libs in cpp?
05:10 < GauravSinghGitte> Hey, @heytanay if you are looking for some plotting tools with cpp, have a look at [this](https://github.com/lava/matplotlib-cpp).

05:38 < RohitKartikGitte> yes, @gaurav-singh1998 matplotlib-cpp is great and easy to work with, also gnuplot.
05:38 < RohitKartikGitte> koolplot is another option, haven't used it though.
05:42 -!- ptk921 [806f3da5@128-111-61-165.vpn.ucsb.edu] has joined #mlpack
05:45 < ptk921> Searching the docs for how to indicate to mlpack that certain column is just an ID, don't consider it part of the data. any tips?
05:47 < jacob-earleGitte> @rcurtin Thanks so much! Excited to get to know the library
06:10 < KhizirSiddiquiGi> ptk921: You can look at some implemented mdoels here at https://github.com/mlpack/models/ for a start. :)
07:13 -!- varun_agarwal [uid424159@gateway/web/irccloud.com/x-umzptachroxfuogy] has joined #mlpack
09:10 < varun_agarwal> Hey, I want to contribute to Pytorch project in GSOC. Whom do i contact?
09:15 < KhizirSiddiquiGi> Hey varun_agarwal, you can message here or email on the mailing list.
09:19 < SaraanshTandonGi> @rcurtin Its taking much longer than 2 hours in #2236
09:21 < varun_agarwal> In the Pytorch modules project, the idea is given but what exactly i need to do? It will help me make my application.
09:25 < SaraanshTandonGi> Is there a pre-application form? If yes what's the deadline?

11:43 < aadarsh-asthanaG> Hi
11:44 < hemal[m]> It is not linking with mlpack and armadillo ...
11:45 < PrinceGuptaGitte> @saraansh1999 that takes quite a lot of time.
11:46 < aadarsh-asthanaG> I would like to contribute to rl methods of mlpack probably implement the acktr and PPO papers
11:46 < hemal[m]> what changes are required with "models/Kaggle/DigitRecognizerCNN/CMakeLists.txt" to be able to run it ?
11:46 < hemal[m]> P.S.
11:46 < hemal[m]> Should I buil the whole models using CMake or, Building DigitRecognizerCNN should work
11:48 < hemal[m]> You could look at these links for a start: https://www.mlpack.org/gsoc.html and https://www.mlpack.org/community.html
11:48 < hemal[m]> Ameet Kumar Rana (Gitter): ^
11:55 < LakshyaOjhaGitte> Hi @zoq can you please have a look at https://github.com/mlpack/mlpack/pull/2174 .
11:55 < LakshyaOjhaGitte> I want to know how to proceed further with this.
11:55 < LakshyaOjhaGitte> Thanks.
11:56 < kartikdutt18Gitt> @hemal, once you run make command, you can find all executables in bin folder
11:56 < kartikdutt18Gitt> The same is

13:57 < TanayMehtaGitter> For the [Issue 2084](https://github.com/mlpack/mlpack/issues/2084), I found [this](https://www.mlpack.org/doc/mlpack-3.2.1/doxygen/namespacemlpack_1_1data.html#ac0441d5f7e76f0fcdeec487d4a9732ac) overload of `mlpack::data::load` function which has a option to pass in a specified file format. I may be wrong but isn't the functionality of manually specifying a format already implemented as was needed in the Issue?
14:35 < hemal[m]> https://github.com/mlpack/mlpack/pull/2135
14:37 < hemal[m]> Tanay Mehta (Gitter): A pull request is open for the issue. I am not sure if the functionality is implemented (since the PR seems stale (over a month since any new activity)). Perhaps, you could have a look at the PR mentioned above
14:40 < TanayMehtaGitter> @hemal I was just looking at the PR, It failed in Memory checks. Also looking at the old comments, it seems that the person who took it was trying to replicate a function to guess the file-type similar to what has been done in arma internals. Might've been a slight disagreement there i guess
14:46 < hemal[m]> the format mentioned in https://www.mlpack.org/doc/mlpack-3.2.1/doxygen/namespacemlpack_1_1data.html#a387137c43ed9616d39ba90e890d181eb states text, xml, binary, etc
14:48 < hemal[m]> I think the requirement was to be able to use arma_binary, arma_ascii, as mentioned here: http://arma.sourceforge.net/docs.html
14:49 < hemal[m]> rcurtin: am i right, regarding the requirement?
15:03 -!- ImQ009 [~ImQ009@unaffiliated/imq009] has joined #mlpack
16:45 < rcurtin> I haven't taken a look at the existing PR in a little while; it might be just fine, I just haven't gotten around to it
16:45 < rcurtin> no reason to start another one, in my opinion
16:47 < TanayMehtaGitter> @rcurtin yeah I am focusing more on examples now!
16:47 < rcurtin> sounds good :)
17:26 < SriramSKGitter[m> @rahulverma7788 : Hi :) Have a look at https://www.mlpack.org/gsoc.html and https://www.mlpack.org/community.html

18:33 < KhizirSiddiquiGi> hi basuki
18:35 < PrinceGuptaGitte> Hi @khizirsiddiqui , I've implemented model.summary() function, can you have a look at it when you're free. (Right now I'm using std::cout instead of Log::Info because it was causing unknown problems I'll fix that soon). Thanks.
18:35 < PrinceGuptaGitte> PR #2237
18:37 < PrinceGuptaGitte> Can we not chain `<<` in `Log::Info` like we can in `std::cout`
19:16 -!- ImQ009 [~ImQ009@unaffiliated/imq009] has quit [Quit: Leaving]
19:20 < zoq> Sure you can, use <<.
19:24 -!- simplesit[m] [simplesitm@gateway/shell/matrix.org/x-mevmwbuyoenogmjs] has left #mlpack ["User left"]

20:06 < rcurtin> zoq: I don't seem to have permission to cancel appveyor jobs; could I ask you to cancel all mlpack-wheels builds except 1.0.142 please? :)
20:07 < zoq> rcurtin: ahh the permission issue
20:08 < rcurtin> I dunno, maybe we can ping appveyor support, but it doesn't usually make too much of a difference for me
20:08 < rcurtin> anyway, thanks for canceling them all :)
20:08 < zoq> done
20:08 < zoq> happy to help :)
20:08 < rcurtin> :)
20:09 < rcurtin> I think I am getting close to getting this Windows wheel build fixed... but I shouldn't say that, because I'm not actually sure...
20:09 < zoq> HimanshuPathak: Sure, it's on my list.
20:10 < zoq> I wonder what the electric bill looks like
20:11 < zoq> "We will no longer be sending tshirts for GSoC programs (to students or mentors). " ... that is a bummer :(
20:12 < himanshu_pathak[> > I think I am getting close to getting this Windows wheel build fixed... but I shouldn't say that, because I'm not actually sure...
20:12 < himanshu_pathak[> rcurtin: If we get windows wheel fixed the we can also use it in conda build
20:13 < himanshu_pathak[> It will be helpfull for that also
20:14 < himanshu_pathak[> * > I think I am getting close to getting this Windows wheel build fixed... but I shouldn't say that, because I'm not actually sure...
20:14 < himanshu_pathak[> rcurtin: If we get windows wheel build fixed the we can also use it in conda build
20:20 < rcurtin> yeah, perhaps
20:20 < rcurtin> it seemed like the conda build failure was a little bit different... I don't know how related the failures are
20:20 < rcurtin> I'll try and take a look at the current status of the conda build soon, but it is definitely not easy
20:20 < rcurtin> one of the things that really helped me out with the wheel build is that appveyor lets you remote desktop in to the node after it's finished building, so I was able to interactively explore what was wrong
20:20 < rcurtin> do you think there is something similar for the conda build? it could be helpful
20:24 < himanshu_pathak[> Can you provide a link to the windows wheel build. So that I can see is there any similarities between these two
20:24 < rcurtin> https://ci.appveyor.com/project/mlpack/mlpack-wheels/history
20:24 < rcurtin> the history goes on forever... just a field of failing red builds :)
20:24 < himanshu_pathak[> Thanks
20:24 < rcurtin> for that particular build, the issue is primarily that the right runtime DLLs aren't in place when the python bindings are being generated
20:25 < rcurtin> but this is different than the conda issue, where it seems like it is not properly linking against boost
20:31 < LakshyaOjhaGitte> Hey guys I am a little confused about the pr's can anybody help ahead.
20:31 < himanshu_pathak[> Yes failures are quite different I think there is something different about azure and appveyor environment
20:42 < himanshu_pathak[> Hey rcurtin I think we dealing with the same If look at scenario2 here https://support.microsoft.com/en-in/help/815645/you-receive-a-fatal-error-lnk1181-error-message-when-you-build-a-manag
20:44 < himanshu_pathak[> * Hey rcurtin I think we dealing with the same If you look at scenario2 here https://support.microsoft.com/en-in/help/815645/you-receive-a-fatal-error-lnk1181-error-message-when-you-build-a-manag
20:45 < himanshu_pathak[> and in my case conda was not able to build adaboost because of boost::program_option() may be possible this error is also beacause of same linking problem but I am not sure
20:47 < himanshu_pathak[> And in your case also we are getting this error LINK : fatal error LNK1181: cannot open input file 'adaboost.cp36-win32.pyd'
20:47 < himanshu_pathak[> Command exited with code 1181
20:48 < himanshu_pathak[> * Hey rcurtin I think we are dealing with the same If you look at scenario2 here https://support.microsoft.com/en-in/help/815645/you-receive-a-fatal-error-lnk1181-error-message-when-you-build-a-manag
21:02 < metahost> rcurtin, zoq: Is the CI for ensmallen down?
21:05 < zoq> metahost: No, we just have to wait for the monthly build to finish, it's using all almost al machines.
21:05 < metahost> Ah okay, thanks! :)
21:06 < rcurtin> yeah, the build queue is down to "only" 169 from over 1000 yesterday :-D
21:06 < metahost> Whoa!
21:06 < rcurtin> himanshu_pathak[: I think the LNK1181 error you found is actually from some manual debugging that I was doing, not from an actual build failure
21:06 < rcurtin> metahost: here's the crazy monthly job: http://ci.mlpack.org/job/docker%20mlpack%20monthly%20build/
21:07 < rcurtin> really useful for finding random test failures, and for finding test failures specific to an individual version of the dependencies
21:09 < metahost> rcurtin: That's an expansive build matrix! :)
21:13 < metahost> The ETA is very high!! (https://imgur.com/a/F89X3ap)
21:14 < rcurtin> yeah, when I worked at Symantec they were very generous about the build systems they were willing to provide, and when I left, they said I could keep using them until they turned them off...
21:14 < rcurtin> ...and 1.5 years later they are still running
21:14 < metahost> :))
21:15 < metahost> That's amazing!
21:23 < zoq> LakshyaOjha: What PR?
22:03 < LakshyaOjhaGitte> oh sorry forgot to mention. But I think you got them anyway. Actually its very late night just going to do some changes right away. Rest I will take up in the morning and thanks for having a look at them :).
22:04 < zoq> LakshyaOjha: Right it's already pretty late, but I think no need to rush anything :)
22:07 < LakshyaOjhaGitte> ok Thanks.
22:07 < LakshyaOjhaGitte> Also If you can tell me the right way for this one https://github.com/mlpack/mlpack/pull/2186#discussion_r384153412 I can do this one pretty quickly.
22:10 < zoq> LakshyaOjha: Done
22:11 < LakshyaOjhaGitte> Thanks for the quick reply.
22:11 < LakshyaOjhaGitte> Night :)
22:12 < zoq> have a good night

22:48 < rcurtin> I hate javascript
22:48 < rcurtin> Feb 25 15:34:49 knife npm[9555]: Error: Internal Server Error
22:48 < rcurtin> sigh
22:49 < zoq> that error message is helpful, I guess in this case I prefere c++ template errors
22:52 < rcurtin> yeah, there's more to it, I wonder if the octokit or probot API changed under me or something like this
22:57 < GauravSinghGitte> Hey @zoq sorry to disturb you again but can you also have a look at [#2191](https://github.com/mlpack/mlpack/pull/2191). Thanks.
23:02 < zoq> GauravSingh: Isn't it late for you too?
23:02 < zoq> I guess most of the people here are night owls :)
23:05 < GauravSinghGitte> Oh sorry!
23:05 < GauravSinghGitte> If I disturb you
23:06 < zoq> Nahh, I just thought it's super late for you.
23:06 < zoq> Isn't it like 2am for you?
23:07 < GauravSinghGitte> Well actually 5
23:07 < GauravSinghGitte> (edited) ... 5 => ... 5 am
23:07 < zoq> okay ... I think we can count that as late :)
23:08 < zoq> or early in the morning
23:09 < GauravSinghGitte> Yeah, I think I should go back to bed now. Sorry once again to disturb you @zoq
23:10 < zoq> No worries, for me it's still early, especially compared to you.
23:11 < zoq> Will take a look at the PR in just a few minutes, so that you have a review once you wake up.
23:12 < GauravSinghGitte> Okay thank you 😊
23:13 < jeffin143[m]> It's 4;30
23:13 < jeffin143[m]> I guess at least in my watch
23:14 < jeffin143[m]> Which part are you in india , for time difference to be this.much :)
23:14 < zoq> and you are still up as well?
23:14 < sreenik[m]> India has one time zone I thought..
23:16 < sreenik[m]> For me I've just woken up
23:16 < zoq> Here it's 0:15
23:17 < zoq> crazy
23:18 < jeffin143[m]> Zoq : have to submit a early release today morning 😜
23:19 < jeffin143[m]> Office attroocities
23:19 < jeffin143[m]> atrocities*
23:19 < zoq> Well best of luck with the release, I guess :)
23:20 < jeffin143[m]> Sreenik : someone wanted to get in touch with you here , if I fondly remember it right
23:20 < jeffin143[m]> Just go through for logs once
23:21 < jeffin143[m]> Zoq : just wanted to inform all , I am currently building a poc - mlpack-board (dashboard for visual) just like tensorboard during my weekends
23:21 < zoq> Ahh, most of the people I know start with a coffee, but I think reading mlpack message is also a good way to start the day :)
23:22 < zoq> Ohh nice!
23:22 < zoq> If you have anything to show, happy to take a look at.
23:23 < sreenik[m]> jeffin143[m]: Thanks for pointing out. I'll go update the project description now to something clearer
23:23 < sreenik[m]> jeffin143[m]: Sounds great!
23:25 < jeffin143[m]> Ummm the flow is messy for a developer , but I wanted to follow @rcurtin approach of not adding any dependancy , so I resort to boost::asio to send data to frontend
23:25 < jeffin143[m]> Once I am ready with intial things I would get in touch with you
23:25 < jeffin143[m]> Actually I have thought of many solutions but this was the one I thought which could be apt
23:26 < jeffin143[m]> I have others up my sleeves , I have pend it down, I just know have to check which may be the best , will definitely get in touch with you when I am somewhat ready with the poc
23:26 < jeffin143[m]> > I have others up my sleeves , I have pend it down, I just know have to check which may be the best , will definitely get in touch with you when I am somewhat ready with the poc
23:26 < jeffin143[m]> Now*
23:31 < zoq> Sounds good, I guess there are multiple solutions to get the data out, but we just have to start with one.
