06:54 < ssk99> Hi guys, one of my unit tests is failing while building with azure. However, the test passes locally. Does anyone have any idea why this might happen?

06:57 < chopper_inbound[> ssk99: Can you provide the reference/link of failed build.
07:00 < ssk99> Ah sorry, never mind. The test fails locally too. Was using a previous version of the build which is why it passed locally. Thanks for the quick reply chopper_inbound[

12:55 < metahost> zoq: Marcus I have added an example for the method I proposed. Please have a look when you can! :)
13:44 < Param-29Gitter[m> Hello, I wanted to know what is second parameter in constructor of arma::vec in gini gain. For example arma::vec counts(countSpace.memptr(), numClasses, false, true);
14:28 < PrinceGuptaGitte> Hi @Param-29 `arma::vec counts(countSpace.memptr(), numClasses, false, true);` This constructs a vector object that uses data at the memory location: `countSpace.memptr()`, numClasses determines the number of elements to take from that memory location. Third agrument determines whether this memory will be copied or not and last argument tell whether the size can change or not.
14:28 < PrinceGuptaGitte> So in your example your making arma::vec object from memory at location countSpace.memptr() with no. of elements = numClasses. It's not making a copy of that memory and you can't change the size of vector.
14:28 < PrinceGuptaGitte> I hope this clarifies your query.
14:39 < Param-29Gitter[m> Yes it did. Thank you :)

17:42 < Param-29Gitter[m> @kartikdutt18 @zoq @rcurtin I have tried to improve performace #2169 Please do have a look :)
17:56 < kartikdutt18Gitt> Hi @Param-29, could you make the link accessible, it's asking for permission. Thanks.
17:58 < Param-29Gitter[m> Yes. I have made it accessible...
18:06 < sailor[m]> zoq thanks
18:42 < zoq> jeffin143: The progress bar depends on batches, at least the current implementation requires batches, but it's possible to provide an implementation that works without batches as well.
18:42 < zoq> jeffin143: But to answer your question, StoreBestCoordinates should work with any optimizer.
