07:02 < rahulprasad> hello. I am new here and want to contribute to this project.

07:03 < rahulprasad> I am currently doing online course on machine learning.

07:04 < rahulprasad> I have studied linear regression, logistic regression, feature scaling, regularization, multi-class classification and I am currently studying about neural networks.

07:04 < rahulprasad> I have also implemented few of these models but on matlab.

07:04 < rahulprasad> Should I drop the course and start trying to contribute here or should I first finish the complete course?

07:19 < kartik_> kartik@Jarvis:~/MachineLearning/openSource/emulator/nes/build$ cmake . -- Boost version: 1.58.0 -- Found the following Boost libraries: -- system -- thread -- chrono -- date_time -- atomic CMake Warning at CMakeLists.txt:39 (find_package): Found package configuration file: /usr/local/share/OpenCV/OpenCVConfig.cmake but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be NOT FOUND. CMake Error: T

07:20 < kartik_> but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: MLPACK_INCLUDE_DIR used as include directory in directory /home/kartik/MachineLearning/openSource/emulator/nes used as include directory in directory /home/kartik/MachineLearning/openSource/emulator/nes used as include directory in directory /home/kartik/MachineLearning/openSource/emulator/nes

07:21 < kartik_> imgetting the above error while running cmake for nes emulator

07:22 < kartik_> <zoq> i have also installed all the dependacies u have stated on the emulator page

07:34 < kartik_> the above line is fixed .. i specified path to the include directory

07:35 < kartik_> make doesnt works now

07:36 < kartik_> https://ghostbin.com/paste/4p6c8

07:39 < kartik_> i have gcc and not gcc46 in lib folder..

07:49 < kartik_> used cmake -D MLPACK_INCLUDE_DIR=/usr/local/include/mlpack .. to correct the include path

16:53 < rcurtin> zoq: wow, big PR, I'm excited to look through it :)

16:57 < zoq> rcurtin: Let's see if the travis and appveyor build passes.

17:00 < rcurtin> yeah, it turns out the appveyor fix was easy, so if it fails, you can backport the patch I merged yesterday

17:00 < rcurtin> but I have absolutely no idea why that line was causing a problem that looked entirely unrelated

17:00 < rcurtin> must be some visual studio bug or something like that... I'm just glad to have it solved

17:05 < zoq> hm, I thought I updated my branch...

17:11 < rcurtin> oh, I didn't see, maybe you did and I overlooked that :)

18:50 < zoq> kartik_: Hello, sorry for the slow reponse, can you remove 'fPIC -Wl -rpath /usr/local/lib/gcc46' from the CMakeLists.txt file and test it again?

18:50 < kartik_> hello <zoq> i have an error building the communication module from source for nes emulator.. cmake -D MLPACK_INCLUDE_DIR=/usr/local/include/mlpack -D MLPACK_LIBRARY=../../../../mlpack-master/build/lib/libmlpack.so ..

18:50 < kartik_> is the above line i used for installing files

18:51 < kartik_> https://ghostbin.com/paste/4p6c8

18:51 < zoq> kartik_: Hello, sorry for the slow reponse, can you remove 'fPIC -Wl -rpath /usr/local/lib/gcc46' from the CMakeLists.txt file and test it again?

18:52 < kartik_> i have gcc folder instead of gcc46 should i change the name to this one?

18:53 < zoq> kartik_: No need, it's a freebsd relict, I wasn't going to commit that.

18:57 < zoq> Also, I've written some code to test the mlpack code against the OpenAI gym framework which also includes the mario environment. I'll can probably push the code later today.

18:57 < zoq> Out for dinner, back later.

19:15 < kartik_> reached 50% build now .. :D much better..

19:15 < kartik_> https://ghostbin.com/paste/9obr8/edit

19:16 < kartik_> error in super mario bros cpp file ..

19:28 < kartik_> <zoq> thanks for your efforts.. and yeah i read the logs on mlpack site..

19:31 < zoq> kartik_: Can you make sure that you link against Bang's ne branch: https://github.com/BangLiu/mlpack/tree/ne/src/mlpack/methods/ne

19:31 < zoq> Just clone Bang's repo (git clone https://github.com/BangLiu/mlpack.git) and checkout the ne branch (git checkout ne) and then build mlpack (mkdir build && cd build && make)

19:50 < Kirizaki> hi!

19:55 < Kirizaki> which algorithm is best for searching random binary tree?

19:56 < Kirizaki> my example is to find all nodes at the same depth by given node

19:56 < rcurtin> hi Kirizaki

19:56 < rcurtin> I guess I am not sure I understand the problem completely

19:57 < rcurtin> you have a random binary tree, and you want to get all of the nodes at a particular depth?

19:57 < Kirizaki> yes

19:58 < Kirizaki> and my input is node of that random tree

19:58 < rcurtin> I think just a depth-first search is fine for this

20:02 < kartik_> <zoq> im reinstalling mlpack by bangs directory. found the parameter.hpp fine in his directory .

20:02 < kartik_> lets see if things work out well

20:02 < kartik_> :)

20:45 < kartik_> hey <zoq> i screwed things up .. i reinstslled using bang lui repo and tested where mlpack seems to be running all fine..

20:45 < kartik_> new error come in for cmake and make in nes

20:45 < kartik_> https://ghostbin.com/paste/9mjay

20:45 < kartik_> here's the error

20:47 < rcurtin> kartik_: you might want to reconfigure the nes project with CMake

20:47 < rcurtin> like 'rm CMakeCache.txt' and then re-run CMake the way you did to configure it

20:47 < rcurtin> I guess /home/kartik/MachineLearning/openSource/emulator/mlpack/lib/libmlpack.so doesn't exist anymore

20:47 < rcurtin> so reconfiguring CMake should help it find the new one and properly link against it

20:47 < rcurtin> however, I haven't been following the discussion you've had with zoq, so maybe my advice is out of place, hopefully it is useful though :)

20:47 < kartik_> thanks ..let me try this

20:48 < kartik_> no it is..

20:53 < zoq> hm, did you reconfigured the project with cmake -D MLPACK_INCLUDE_DIR=.... MLPACK_LIBRARY=....?

21:06 < kartik_> yes i did

21:06 < kartik_> i have bang lui repo installed

21:07 < kartik_> back tothe same error now

21:09 < kartik_> checkout ne works .. whats the build then u are talking about

21:10 < kartik_> i have installed new bangs repo .. wont theis fix the issue

21:13 < zoq> yeah, this should fix the 'parameters.hpp not found' issue. Can you check if you can find the parameters.hpp header file in build/include?

21:47 < kartik_> ur right

21:47 < kartik_> in include .. i dont have ne

21:48 < kartik_> <zoq> have a look https://ghostbin.com/paste/25ce3

21:49 < zoq> What's the output of 'git branch'?

21:50 < kartik_> master

21:50 < kartik_> *ne

21:58 < zoq> Actually Bang's master branch also builds the ne part, so the branch shouldn't matter.

22:02 < zoq> Do you have mlpack header files in /usr/local/include/?

22:02 < kartik_> yes

22:03 < kartik_> usr/local/include/mlpack/method

22:03 < kartik_> where ne is not present

22:05 < zoq> Just to be sure, you checked for the parameter.hpp file in the build directory?

22:07 < kartik_> no.. can u give me an example path ..

22:09 < kartik_> my mlpack directory has nothing in build due to cmake error .. and i just run the make file without build foler

22:09 < kartik_> *folder

22:09 < zoq> That's so strange: https://github.com/BangLiu/mlpack/tree/master/src/mlpack/methods/ne that's the ne project and there is definitely an parameters.hpp file which is also included into the CMakeLists.txt file.

22:09 < zoq> Sure, just give me a few minutes.

22:12 < kartik_> yup i have it here /home/kartik/MachineLearning/openSource/mlpack/include/mlpack/methods/

22:15 < zoq> so this is what I did: https://gist.github.com/zoq/958097cd0e48f468280fa7215d8dfa79

22:22 < kartik_> let me just delete everything

22:22 < kartik_> and start from zero

22:22 < zoq> okay

22:22 < kartik_> to implement only the given commands

22:24 < kartik_> whats ne project on line 10

22:24 < kartik_> oh the emulatorr

22:24 < zoq> yeah, right

22:25 < kartik_> thanks a lot zoq .. trying all this since 2 days..

22:26 < zoq> Hope we can figure this out :)

22:26 < kartik_> :)

23:20 < kartik_> so i did everything again..

23:21 < kartik_> and this time in usr/local/mlpack/include/method has ne included

23:22 < kartik_> i followed exactly accordingto instruction file .. except did 'make install ' after mlpack build and changed cmake in nes to enable c++11 standards

23:23 < kartik_> https://ghostbin.com/paste/4mtcv heres the error log

23:27 < zoq> oh, the good thing is I know a solution for that the sad thing is, you need to build mlpack again ...

23:29 < zoq> I forgotten that I made some changes, in my ne branch: https://github.com/zoq/mlpack/tree/ne/src/mlpack/methods/ne, so instead of using Bang's repo you should use mine.
