03:02 < RishabhGarg108Gi> @birm I dont know how to do that. Could you tell.

03:02 < RishabhGarg108Gi> I just did the regular cmake ../

03:09 < AakashkaushikGit> Hey @birm , not completely sure but the python bindings are turned off by default in the master branch right ?

03:26 < birm[m]> Aakash kaushik (Gitter): yes. So, RishabhGarg108 (Gitter) pass the option to enable python binding with with -D BUILD_PYTHON_BINDINGS=ON on the cmake step. Then, see if the cmake output seems satisfied with the dependencies.

03:27 < birm[m]> Hope that's useful. You may also find the cmake guide helpful, https://github.com/mlpack/mlpack/wiki/UsingCMake

04:26 < RishabhGarg108Gi> After enabling python binding, cmake is showing error that pandas is not installed, although i have pandas installed through pip3

04:57 < yashwants19[m]> [RishabhGarg108 (Gitter)](https://matrix.to/#/@gitter_rishabhgarg108:matrix.org) Have you tried -DPYTHON_EXECUTABLE=/urs/bin/python3 with cmake?

04:58 < yashwants19[m]> * [RishabhGarg108 (Gitter)](https://matrix.to/#/@gitter_rishabhgarg108:matrix.org) Have you tried -DPYTHON_EXECUTABLE=/usr/bin/python3 with cmake?

05:02 < AakashkaushikGit> @rishab-gangwar if you are on a linux based system try installing pandas through apt or something similar

05:04 < AakashkaushikGit> The package name is `python3-pandas`

06:22 < RishabhGarg108Gi> Hii @yashwants19 , I tried with -DPYTHON_EXECUTABLE, but it was showing some error with R bindings, so I also added -DBUILD_R_BINDINGS=OFF. But that too had no effect

06:22 < RishabhGarg108Gi> Hey @Aakash-kaushik , I installed python3-pandas, but it is still showing pandas not found

06:24 < RishabhGarg108Gi> This is the error that I am getting

06:26 < yashwants19[m]> Try install pandas using /usr/bin/python3 -m pip install pandas

06:27 < yashwants19[m]> And then use cmake -DPYTHON_EXECUTABLE=/usr/bin/python3 ..

06:27 < RishabhGarg108Gi> @yashwants19 , I already have the latest pip version of pandas which i am regularly using.

06:30 < RishabhGarg108Gi> I installed pandas as you just mentioned and again did cmake. This time it showed come error with go bindings, so i turned off the go bindings and the output that i got from cmake is :-

06:31 < RishabhGarg108Gi> It is still saying Not building python bindings

06:31 < yashwants19[m]> python bindings is disabled some how.

06:32 < yashwants19[m]> Try to remove CMakeCache.txt from you build folder.

06:33 < yashwants19[m]> And then simply cmake -DBUILD_PYTHON_BINDINGS=1 -DPYTHON_EXECUTABLE=/usr/bin/python3 ..

06:33 < RishabhGarg108Gi> I explicitly turned on the python bindings along with the previous cmake options and it somehow started building something. I an hoping that it is now building python bindings.

06:34 < yashwants19[m]> Awesome.

06:34 < yashwants19[m]> You simply make python bindings using.

06:34 < yashwants19[m]> make python

06:34 < RishabhGarg108Gi> Will update you in a short while when it finishes building

06:35 < RishabhGarg108Gi> ok..

07:17 < RishabhGarg108Gi> while doing sudo make install, i am getting this

07:29 < RishabhGarg108Gi> I have cython version 0.29.21. and when i try to run from Cython.Distutils import build_ext from python3 on terminal, it is working fine

07:31 < yashwants19[m]> Did `make install` succeed properly.

07:31 < yashwants19[m]> * Did `make` succeed properly.

07:32 < RishabhGarg108Gi> Yeah 'make' succeed.

07:35 < RishabhGarg108Gi> Finally, sudo apt-get install cython3 worked. Now i am able to import mlpack in python

07:35 < RishabhGarg108Gi> Thanks @yashwants19 and @Aakash-kaushik for helping me.

07:46 < AakashkaushikGit> :D

08:29 < manasd28> Hi I wanted to ask how can we test the changes we in the source code in our local machine?

08:44 < AakashkaushikGit> You can create a build folder in the mlpack local repo that you have and in the build folder you can do `cmake ../` and then `make` if you prefer to don't install in system wide or `make install` if you prefer to do so, also you maybe need to specify a `jN` flag to limit how many thread make uses to build mlpack

08:44 < AakashkaushikGit> If you encounter a out of memory situation reduce the number of `N` in that flag

08:45 < AakashkaushikGit> @manasd28 ^

08:46 < manasd28> So basically build again..Thanks!!

08:46 < AakashkaushikGit> Yup .!

08:47 < AakashkaushikGit> Also you can find the basic information [here](https://www.mlpack.org/docs.html).

08:49 < manasd28> Thanks.

12:14 < RishabhGarg108Gi> Hey everyone, I am am an absolute beginner at the technologies used in the library and working on mlpack would be my first project. I know basic c++, python and machine learning. But I know nothing about armadillo, boost, cmake, catch, lapack, serialization etc. I am willing to learn all these new stuffs. So, could someone tell me how do i go about learning these things. I need something like a road map so that I

12:14 < RishabhGarg108Gi> could learn them one at a time and do some contributions to the library. Also, if someone could suggest me some basic issue which could help me understand the codebase. I would really appreciate some help. Thanks.

12:17 < zoq> RishabhGarg108Gi: Hello, there are some issues on GitHub tagged with "good first issue", you can list them by clicking the tag on the community page - https://www.mlpack.org/community.html.

12:19 < zoq> RishabhGarg108Gi: Starting with an issue is a good starting point, in most cases you don't have to touch cmake, serialization, boost.

12:20 < zoq> RishabhGarg108Gi: We have listed some books and tutorials to dive into some of the used paradigm here - https://www.mlpack.org/gsoc.html

12:54 < RishabhGarg108Gi> Thanks @zoq , I would take a look at all of these resources. These resources looks like a great starting point for me. Thanks for helping.

13:24 < HavshxjdnaggzGit> Hello, when I want to compare the neighbors to an int value I got error if (Neighbors.col(i) == y) how can I fix that?

13:25 < rcurtin> HavshxjdnaggzGit: for the most part, the questions you're asking are pretty basic C++ questions and aren't specific to mlpack; I think you might have more success getting answers and understanding what's wrong by either consulting a C++ textbook, or perhaps asking the question on a larger C++ forum like StackOverflow

17:54 < abernauer[m]> zoq: So I created a branch on my fork added my notebook, the install.R and runtime.txt. Does that hit the check list for opening the PR for that R notebook.

18:54 < zoq> abernauer[m]: Sounds good, let's open the PR and see if that works :)

18:55 < abernauer[m]> I tried building it on the mlpack lab link and it returned a 404 error

18:56 < zoq> Hm, I'll take a look once the PR is open.

19:06 < rcurtin> abernauer[m]: awesome, great to see the example coming together!

19:08 < abernauer[m]> rcurtin: Enjoyed writing the example! Splitting time on the examples and working on a side project for a discord bot written in Python with two other contributors.

20:09 < rcurtin> nice, sounds like a good time :)

20:09 < abernauer[m]> Yeah I have to deal with coroutines which is new to me.

21:08 < rcurtin> birm[m]: I was quite surprised to be trying to figure out some path traversal implementations for work and my digging brought me to an answer from you: https://github.com/JuliaGraphs/LightGraphs.jl/issues/1456

21:08 < rcurtin> I didn't know you were involved with LightGraphs :-D

21:25 < birm[m]> rcurtin: haven't contributed in a little while now, I should resume!
