08:10 < jenkins-mlpack2> Project docker mlpack nightly build build #308: STILL UNSTABLE in 3 hr 56 min: http://ci.mlpack.org/job/docker%20mlpack%20nightly%20build/308/

13:08 < mulx10> jeffin143: Exactly :p

13:09 < mulx10> exams are a bit tiring

13:51 < jeffin143> rcurtin , zoq : I went through the layers folder in ann dir and couldn't find a suppprt for ' flatten layer ' and also a ' reshape layer'

13:56 < jeffin143> Is it there ?, and if not I would like to implement these two layers* since i find it would be good to add a support to flatten a layer and also reshape it . Though i would like to hear from both of you too.

14:13 < zoq> jeffin143: Right, I guess reshape could do the same as flatten?

14:17 < jeffin143> Oh wow , did think that way. Umm there is one more query , is there any support in armadillo to reshape from 2 d to a 3d , basically from mat to cube

14:17 < jeffin143> What i mean to say is there is an array of size 100*100 what i want to do is reshape it to 10*10*100 ..??

14:17 < jeffin143> Can i achieve it..?? Couldn't find going through documentation . May be i would have over looked

14:19 < zoq> using the advanced constructor and memptr; https://github.com/mlpack/mlpack/blob/a009898374d9e9e5a17132a4e39eba9f71d12906/src/mlpack/methods/ann/layer/convolution_impl.hpp#L94-L95 is an example

14:21 < jeffin143> Thanks, would go through it :)

15:54 < hsankesara> Hey community, I am working on a PR and I need to run tests on my local PC to make sure they are working. Since CMake file of test is big and I only need to test few method, I deleted unwanted tests from CMake. Then when run make mlpack_test, I am getting that error:- /usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/gcrt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: error: ld returned 1

15:56 < hsankesara> I am trying to debug it from hours now but couldn't. Any help will be appreciated.

15:56 < zoq> hsankesara: Did you comment mlpack_test.cpp?

15:57 < hsankesara> Yeah, I did that.

15:57 < zoq> The file is the entry point for the test cases (main(..))

15:59 < zoq> So this is one file that you shouldn't remove the the CMake file.

15:59 < hsankesara> Oh my bad, I commented everything except the desired ones. Thanks for helping.

16:00 < zoq> you might also need test_function_tools.hpp, test_tools.hpp, serialization.cpp and serialization.hpp

16:00 < zoq> also, you might have to delte the tests from: https://github.com/mlpack/mlpack/blob/a009898374d9e9e5a17132a4e39eba9f71d12906/src/mlpack/tests/CMakeLists.txt#L183-L188

16:02 < hsankesara> I deleted the lines. Let me make those other changes and see if it's working. Thank you for the instant reply and help.

16:03 < zoq> Happy to help.
