Hi everyone. My name is Van from Viet Nam. I am currently a third year Computer Science student. I have experience in C++ and general knowledge of Machine Learning. Do you have any suggestions for a beginner like me to participate GSOC?.

Hi , I'm trying to build only the ann module from source but it keeps telling me `make: *** No rule to make target 'mlpack_ann'. Stop.`

* Hi , I'm trying to build only the ann module from source but it keeps telling me `make: *** No rule to make target 'mlpack_ann'. Stop.`
< hunting-party104>
I can build a few modules like det, cf etc but for some like ann, adaboost, amf it gives me that error
< Nakul[m]>
hey you can buid any particular module by getting the corresponding target . for ann you can build by navigate to it's make file for example
< Nakul[m]>
```/home/knakul853/Desktop/mlpack/mlpack/build/src/mlpack/methods/ann``` them running only make would work
< Nakul[m]>
*then
< hunting-party104>
So i can just go to the ann directory and type `make` instead of doing it from the build directory ?
< hunting-party104>
Nope on typing make it doesnt do anything
< Nakul[m]>
hope it helps
< hunting-party104>
Ah wait my bad i didnt see that i had to go into the build directory then the ann, I drectly went to ann the normal route
< zoq>
You can only build targets/executables since there is no executable for the ann code, it will fail.
< hunting-party104>
so is there no way to only build the ann module?
< zoq>
right, you can disable the executables and build the lib only, to speedup the build.
< zoq>
By using -DBUILD_CLI_EXECUTABLES=OFF in the cmake step.
< rcurtin>
Nakul[m]: I would strongly advise against navigating the build directories and using make in the subdirectories
< rcurtin>
instead use 'make <target>' from the top-level build directory
< rcurtin>
please read the CMake documentation to understand more
< hunting-party104>
Sorry im a bit new to cmake zoq how do i build only the lib ? By just typing `make` or `make lib`?
< hunting-party104>
well `make lib` doesnt work so would `make` only build the libraries ?
< rcurtin>
hunting-party104: the target is called 'mlpack' just to build libmlpack.so. so, 'make mlpack'
< rcurtin>
if you're new to CMake, go read some resources about how to use CMake so that it makes sense---that will be a lot more productive in the long run :)
< Nakul[m]>
> Nakul: I would strongly advise against navigating the build directories and using make in the subdirectories
< Nakul[m]>
thanks i wasn't aware about that
< rcurtin>
sure; it really makes a big difference to spend some time getting familiar with the tools, so even if it feels unproductive to read tutorials, etc., it actually is productive, and when you return to the code you will find yourself better positioned to make changes :)
< hunting-party104>
ah ic rcurtin are there any good references for cmake or just a google search would do ?
< rcurtin>
I don't have a preferred resource; I'd suggest searching google
< hunting-party104>
rcurtin:
< hunting-party104>
Also rcurtin i wanted to pursue issue #1631 which was opened by @akhandait whos not on this channel i guess, Could you give any pointers on how i could proceed ?
< rcurtin>
the issue description seems pretty comprehensive to me. if not all of the description makes sense, spend time in the codebase learning it until the issue description fully makes sense
< rcurtin>
then, open a PR with the solution
< rcurtin>
or, I shouldn't say "the solution", just "a solution". there may be more than one :)
< hunting-party104>
<rcurtin "the issue description seems pret"> yes the problem seems straight forward but im not able to understand a few things from the code , like for eg Sequential which calls the destructor only when `const bool model` is `false`
< hunting-party104>
from the destructor
ImQ009 has joined #mlpack
< rcurtin>
hunting-party104: my suggestion would be to spend more time with the Sequential layer and look at how it's used in hte tests, etc., to understand what the 'model' parameter is
< hunting-party104>
Alright will do
< HimanshuPathakGi>
Hey zoq, rcurtin windows build for ensmallen is now enabled all thanks to Marcelo now I will work for mlpack now

How can we join video meetup
< HimanshuPathakGi>
(edited) ... video meetup => ... video meetup?
< zoq>
Just follow the zoom link in the mail.
< abernauer[m]>
Set up a zoom account the link to the chat is in the mailing list btw.
Ayush has quit [Ping timeout: 260 seconds]
< HimanshuPathakGi>
ok thanks I will do
< rcurtin>
can someone try to join the zoom for the weekly meetup? I think I have changed my zoom account settings so anyone should be able to join at any time
< rcurtin>
so it shouldn't say "please wait for the host to start the meeting"... I hope :)
< zoq>
Nope, "please wait for the host to start the meeting"
< abernauer[m]>
Yeah I got the same thing.
< zoq>
rcurtin: meeting id is 3820896170?
< birm[m]>
I thought it was scheduled for 2200 UTC
< abernauer[m]>
He is just confirming if it will start the call if he's not present
< abernauer[m]>
Or meeting.
< rcurtin>
zoq: yeah, that's the right id. I guess I didn't get it right
< rcurtin>
let's see what happens if I actually schedule a meeting...
< rcurtin>
actually I see, I just made the change in the wrong configuration page. can you try joining the 3820896170 meeting again?

Hi zoq just checking out slack
< ToshalAgrawal[m]>
@freenode_rcurtin: I hope this works.

< zoq>
ToshalAgrawal: Sounds good :)

zoq: awesome, glad it works
< rcurtin>
ToshalAgrawal[m]: let me know if you have any problems using slack... I think the bridge works fine and is stable though :)
< jeffin143[m]>
:) They would be really heavy on my pocket , but i am really after swags
< jeffin143[m]>
Probably have to mail for Mlpack stickers , Haven't done till now
< rcurtin>
:) I'd be happy to toss some in the mail for you

can anyone help me with this ```difference{-nan%} between arma::sum(probabilities.col(i)){-nan} and 1.0{1} exceeds 1.0000000000000001e-05%```
AbhinavvermaGitt has joined #mlpack
< AbhinavvermaGitt>
Do mlpack can be built on the 32-bit window.
< zoq>
Abhinavverma: yes
< rcurtin>
Nakul[m]: do you understand the meaning of the error message?
< Nakul[m]>
in probabilites matrix there are some value which are nan(not a number)
< Nakul[m]>
and when we are passing to the boost for testing the this error messge shows up
< Nakul[m]>
i tried checking by ```std::isnana(the value)```
< Nakul[m]>
and then pass it for testing but seems not working..:(
< Nakul[m]>
> Nakul: do you understand the meaning of the error message?
< Nakul[m]>
not realy ?
< Nakul[m]>
basically this error comes from here ``` BOOST_REQUIRE_CLOSE(arma::sum(probabilities.col(i)) , 1.0, 1e-5);
< Nakul[m]>
```
< Nakul[m]>
* basically this error comes from here ``` BOOST_REQUIRE_CLOSE(arma::sum(probabilities.col(i)) , 1.0, 1e-5);```
< Nakul[m]>
any refrence would be helpful , since simply googling seems not helpful
< rcurtin>
ok, so a place to start would be to find documentation for BOOST_REQUIRE_CLOSE
< rcurtin>
that's a part of the Boost Unit Test Framework
< rcurtin>
once you understand that, you will be able to understand what has actually happened that has caused the test to fail
< rcurtin>
then, you can read the rest of the test in order to understand what is being tested
< rcurtin>
and from there you can reason to determine what is wrong
< Nakul[m]>
@rcurtin:matrix.org: thanks
< rcurtin>
I know that I am not being immediately helpful by telling you what the issue is, but, if you take the time to dig in deeper and learn what's going on you will be much more effective overall :)
< rcurtin>
also, unfortunately it looks like I won't be able to make the video meetup. I'm stuck in company meetings all afternoon
< Nakul[m]>

I wonder if this is a late "meeting" for everybody or just me :)
< rcurtin>
well, at least someone who filled out the survey said it was a good time :)
< zoq>
haha, maybe for someone it's lunch time.
< zoq>
Will use the time to review a PR.
< rcurtin>
I keep getting emails that say "your meeting participants are waiting", but did you manage to join ok?
