01:09 < HimanshuPathakGi> Hey zoq rcurtin do we have implementation flatten layer in ann module
01:11 < HimanshuPathakGi> I try to find it but not there in layer
02:41 < kartikdutt18Gitt> Hi @himanshupathak21061998, I don't think we have flatten but its simply resizing the output cube/mat to given number of channels. I think its more related to armadillo than ann.
02:41 < kartikdutt18Gitt> https://discuss.pytorch.org/t/flatten-layer-of-pytorch-build-by-sequential-container/5983
02:41 < kartikdutt18Gitt> Refer the conversation above or pytorch documentation.
02:49 < HimanshuPathakGi> Yes it is more related to armadillo but may be we should include this but it is quite simple to change shape
02:51 < kartikdutt18Gitt> Yes armadillo has .resize() to simply change the number of channels.
02:52 < HimanshuPathakGi> It is lot easier so we don't need it

11:27 < zoq> HimanshuPathak: Internally, everything is just continuous memory, so if you need to flatten the input/output you could always do something like: arma::Mat(input.memptr(), 1, input.n_elem()), and that will give you a flattern version of the input whitout any speed penalty.

11:48 < GauravSinghGitte> Hi everyone, during the past few days I was getting acquainted with the mlpack repository and to contribute it by implementing the GELU activation function. Should I go ahead and open an issue and start working on it?
11:51 < zoq> GauravSingh: Hello, sounds good please feel free to open an issue and a PR.
11:53 < Nakul[m]> @zoq I was thinking to start working on mlpack cmake
11:54 < zoq> Nakul[m]: If you are down for a challenge, the bindings part might be tricky.
11:58 < kartikdutt18Gitt> Hi @zoq, if you get the chance kindly have a look at PR #38 in models repo, I made the changes you requested in the same.Thanks.
11:58 < zoq> kartikdutt18: will do
11:58 < Nakul[m]> Here someone doing something for visualization ? Just curious
11:59 < Nakul[m]> > Nakul: If you are down for a challenge, the bindings part might be tricky.
11:59 < Nakul[m]> Okk
12:10 < kartikdutt18Gitt> @zoq, Could you help me out with this https://github.com/mlpack/mlpack/pull/2172/files#r375798353, I can't seem to get testing right

16:00 < HimanshuPathakGi> Thanks zoq I will try this arma::Mat(input.memptr(), 1, input.n_elem()) next time.
17:09 < PrinceGuptaGitte> Hi, I have a question regarding activation functions.
17:10 < PrinceGuptaGitte> Currently the deriv() function takes input y then calculates f'(x) where f(x) = y
17:13 -!- UmarJ [~UmarJ@111.68.97.205] has joined #mlpack
17:15 < zoq> PrinceGupta: right
17:15 < zoq> PrinceGupta: f'(f(x) )
17:26 * PrinceGuptaGitte sent a long message: < https://matrix.org/_matrix/media/r0/download/matrix.org/LFTXSeDwEombJsKsTWZVBDHQ >
17:28 < zoq> PrinceGupta: I see the comment is confusing.
17:32 < kartikdutt18Gitt> Hi @prince776, I think you are right, that's a typo.
17:43 < PrinceGuptaGitte> Hi, I implemented ISRU function for issue #2181 but when I built it, it didn't build the new create file isru_function.hpp, am I missing something?
17:44 < kartikdutt18Gitt> Hi I think you didn't add in cmakeFile.txt
17:44 < kartikdutt18Gitt> src/mlpack/methods/ann/activation_functions/CMakeLists.txt
17:44 < PrinceGuptaGitte> oh i totally forgot thanks a lot
17:45 < kartikdutt18Gitt> Not an issue, could you also leave a comment on #2181 so that other people don't end up working on the same issue.
17:46 < kartikdutt18Gitt> Thanks.
18:03 < metahost> Hi everyone, the meeting's live! Here's the link: https://zoom.us/j/3820896170

18:12 < zoq> kartikdutt18: Yes, once I have a chance I will look into it and leave a comment.

18:16 < AbhinavvermaGitt> libstb-dev showing error while I m trying to install the package through command sudo apt-get install libstb-dev in my 32 bit Linux mint. Do we any alternative for the same.
18:18 < kartikdutt18Gitt> Hi @abhiverma1924, could you paste the error log? Thanks.

18:21 < AbhinavvermaGitt> Error : Unable to locate package libstb-dev
18:22 < AbhinavvermaGitt> @kartikdutt18
18:23 < zoq> Abhinavverma: Not sure there is a libstb-dev package, isn't it header only? Anyway, if you buld mlpack using cmake, it will download the file for you.
18:25 < kartikdutt18Gitt> I think libstb-dev is only available in (very) recent versions of ubuntu (I referred this https://pkgs.org/download/libstb-dev )
18:34 < PrinceGuptaGitte> @zoq yea it really confused me about how it's working. I had to look into other activation function files and base_layer to confirm.
18:35 < AbhinavvermaGitt> @kartikdutt18 I have already checked this link before there is no version for 32 bit.
