02:25 < PrinceGuptaGitte> I just saw now that convolution also take 2D inputs of dim (num samples, num features) and not 3d or 4d like(num samples, channels, width, height) like in keras.

02:25 < PrinceGuptaGitte> I was thinking it's a little odd, but it's also easier to maintain 2d tensors(mat)

02:26 < PrinceGuptaGitte> (Num features, num samples) *

05:05 < Rudra> Hello,

06:13 < TanayMehtaGitter> I have a question, I know there are Neural nets in mlpack, but they should have something for automatic differentiation (like autograd for Pytorch) but I don't have any directions,

07:38 < GauravSinghGitte> Hi, @heytanay you can have look at [this](http://ensmallen.org/docs.html#differentiable-functions).

08:46 < TanayMehtaGitter> @gaurav-singh1998 thanks for the link! I had no idea something like this existed in cpp

11:02 < SaraanshTandonGi> Also the exports to be done for LD_LIBRARY_PATH and PYTHONPATH in the end have been mentioned under the heading "Using mlpack without installing", whereas i needed to do it anyways.

12:37 < Nakul[m]> I think you don't need to master oop concept but basic are enough to get through the code and also.. template is very important.So I would suggest go through some online resources for that.

12:38 < Nakul[m]> Opting any easy issue and solving will clear lots of concept and workflow of the codebase

12:38 < Nakul[m]> And that's important

12:48 < SaraanshTandonGi> Thanks.

12:48 < SaraanshTandonGi> Could you please confirm the reproducability of the above problems cause i see someone has created an issue for a similar problem.

12:48 < SaraanshTandonGi> I would love to get started with a documentation PR to give me a morale boost.

12:58 < GauravSinghGitte> I don't know if this would be helpful but these are some of the articles I referred on the internet for the C++ concepts, [for C++ templates](https://www.codeproject.com/Articles/257589/An-Idiots-Guide-to-Cplusplus-Templates-Part-1), [for getting to know what is SFINAE](https://eli.thegreenplace.net/2014/sfinae-and-enable_if/), [for C++

I think you should start with the good first issues like [this](https://github.com/mlpack/mlpack/issues/2230) and learn side by side. Thanks.

13:24 < TanayMehtaGitter> I am facing 2 problems in building from source. 1. I have armadillo installed but it need version 8.400 and above. 2. When trying to install libensmallen-dev and libstb-dev, it says "unable to locate"

13:24 < TanayMehtaGitter> I'm using Ubuntu 18.04 and trying to build mlpack 3.2.2

13:26 < PrinceGuptaGitte> Hi @heytanay , uninstall libarmadillo-dev through apt-get as it installed lower version than required

13:27 < SaraanshTandonGi> remove the version of armadillo installed by apt-get and build it from source using their official documentation.

13:27 < SaraanshTandonGi> You can skip on libensmallen-dev and libstb-dev, CMake will automatically install them

13:27 < PrinceGuptaGitte> Just like he said then build the appropriate version from source

13:28 < SaraanshTandonGi> I think it would be helpful to mention these small details in the documentation as they would avoid a lot of confusion for new people like me and would make the setup process a lot smoother

13:29 < PrinceGuptaGitte> Yeah I agree.

13:33 < SaraanshTandonGi> I'll try to write up a few modifications to the text. Things to include:

13:33 < SaraanshTandonGi> 1. Remove the armadillo library from the code snippet of apt-get, and add a line instructing to build it from source with a link.

13:33 < SaraanshTandonGi> 2. Remove libensmallen and libstb from the code snippet of apt-get informing about the flag that is by default set and handles the installation of these two automatically.

13:40 < TanayMehtaGitter> @saraansh1999 Good idea, Can I take on this small work? I want to get started contributing ASAP in any way possible. I will write both these points in `Building Mlpack from` source section on Github? What do you say?

13:40 < TanayMehtaGitter> (edited) ... Mlpack from` source section ... => ... Mlpack from source` section ...

13:40 < TanayMehtaGitter> @prince776 will try that rn

13:44 < SaraanshTandonGi> @heytanay actually it will be my first contribution too. So I would like to work on it. :)

13:44 < TanayMehtaGitter> @saraansh1999 Go ahead! All the best!

13:44 < SaraanshTandonGi> @heytanay Thanks a lot mate!

14:46 < TanayMehtaGitter> I'm doing `make` for mlpack on Linux and it's occasionally throwing some deprecation warnings (mostly with Numpy) is that normal?

14:48 < SakshamRastogiGi> @heytanay I face the same warnings on Mac

14:56 < TanayMehtaGitter> @codeboy5 I believe it's okay as long as it's not throwing an error!

15:07 < susanna> Hello everyone!

15:10 < PrinceGuptaGitte> Hi everyone, can anyone who has good understanding of `ann` codebase help me with a doubt.

16:06 < PrinceGuptaGitte> Hi everyone, I'm facing an issue I can't resolve.

16:06 < PrinceGuptaGitte> The problem is I'm calling `boost::apply_visitor(outputWidthvisitor,network[0])` and I'm making sure there is getter `OutputWidth()` in the layer being visited. However it always returns 0. What could be the problem?

16:06 < PrinceGuptaGitte> I tried

16:07 < PrinceGuptaGitte> (edited) ... I tried => ... I tried to dodge it but using `ouputParameterVisitor` but the matrix it returns also shows 0 elements.

16:17 < KhizirSiddiquiGi> @prince776 : Many a times you need to train the layer one epoch at least to get the outputwidth parameter, if I am not wrong. I tried doing this summary thing quite a while ago.

16:18 < KhizirSiddiquiGi> Similar for `outputParameter` also.

16:18 < PrinceGuptaGitte> Oh thanks for the information. Do you have any idea what is the reason behind this

16:19 < PrinceGuptaGitte> Ohhh I understand now why it must be the case

16:20 < PrinceGuptaGitte> Thanks a lot. @khizirsiddiqui . I can finally progress.

16:20 < KhizirSiddiquiGi> :thumbsup: Do it bro, xD one really needs that feature sometimes.

17:17 < vroom_coder> Hey, I am new here !

17:18 < KhizirSiddiquiGi> Hey vroom_coder!

17:18 < vroom_coder> I got to know about mlpack from GSOC and wish to contribute

17:19 < KhizirSiddiquiGi> You could look at these links for a start: https://www.mlpack.org/gsoc.html and https://www.mlpack.org/community.html

17:20 < KhizirSiddiquiGi> Ask here / mailing lists to clear if you have doubts. :)

17:27 < vroom_coder> Thanks for the links! I will follow the steps.

17:27 < vroom_coder> In the Essential Deep Learning Modules project, what are the other algorithms that are expected?

17:29 < aadarsh-as> hi i am a 2nd year undergrad student looking forward to work on reinforcement learning project under gsoc is there someone i can turn to for guidance

17:39 < vroom_coder> I want to contact Sreenik Seal. How can I do that?

17:42 < SriramSKGitter[m> @vroom_coder: Just ping him here with what you'd like to ask. He'll eventually get around to answering your query :)

18:36 < kartikdutt18Gitt> Hi @aadarsh-as, take a look at https://www.mlpack.org/gsoc.html and https://www.mlpack.org/community.html .

20:25 < zoq> vroom_code: as mentioned in the wiki, "it is probably not a great idea to contact mentors directly [...]", better to use the public channels
