I just had a really fascinating and exciting conversation with Sylvain Corlay from QuantStack about C++ and notebooks
< rcurtin>
I didn't know this exists (maybe I live under a rock?) but there is a working C++ notebook environment via 'xeus':
< rcurtin>
given that virtually 100% of data science is in notebooks, and that's native C++ in a notebook, I think it should not be hard to get mlpack running in a notebook!
< rcurtin>
I'm hoping to adapt one of our examples later this week or maybe tomorrow if time permits
< rcurtin>
but I think this could be a huge improvement to our documentation/examples, and could also make it *way* easier for users to *use* mlpack
< rcurtin>
(since they wouldn't have to think about a compiler at all)
< rcurtin>
don't know if anyone else here has ever played with xeus, but, this is the first I've seen it, and it's really really cool and I'm extremely excited

Sylvain specifically told me that they are looking for users of xeus that they can demonstrate at conferences, etc., so I think that there is some exciting potential here

I tested xeus cling, but run into som redefenition issues
< rcurtin>
yeah just hit that, kind of unfortunate, but maybe fixable
< rcurtin>
maybe some workaround can happen, I'll talk to Sylvain tomorrow

< rcurtin>
that is kind of a blocker though... notebooks are a bit unusable if you can't screw up
< zoq>
yeah, I used .undo a lot, but that wasn't really a solution; ended up restarting the kernel more often
< rcurtin>
yeah, I see, that's not a great workaround though
< rcurtin>
one of the commenters writes:
< rcurtin>
I have written a similar interactive kernel for Fortran (https://docs.lfortran.org/) and there I simply shadow the previous definition, the example notebook has an example for that, you can also launch it in Binder to play with that interactively.
< rcurtin>
but perhaps cling has just merged support for this:
< Nakul>
I have sended the PR directly to the master branch is there any problem with that ?

Nakul: Hello, that works.
< Nakul>
how should i download libarmadilo , i am using sudo apt-get install libarmadilo and persistantly getting this error https://pastebin.com/41s6K1t6
< Nakul>
previously i got this working but for some reason i uninstalled and then i got this error
< Nakul>
after instally once again

Nakul: can you tell us a little about how you configured mlpack?
< Nakul>
previously i downloaded zip file , but now i git cloned fron the repo and maded build dir. and then run cmak ../ and after tha make
< Nakul>
after running every methods got builded successfully but at the end i got that error

Nakul: try removing the old armadillo that you downloaded, I think that could help
< jeffin143>
Umm we could add it as optional dependency and then user may be able to pass Lambda function from python and then we can use that function in our c++ class
< jeffin143>
To be specific as of now , a use case is the string binding where tokenizer could be a lambda function , for binding we have used one internal tokenizer but using this we could give user more power to customise it

@lozhnikov : I will go through ngrams implementation and try to implement this week , most probably will start from Wednesday , since I haven't used that , and hence to read a lil bit
