wiking_gf712: do you know why this could happen13:36
wiking_  File "/build/examples/meta/python/evaluation/cross_validation_multiple_kernel_learning_weights_storage.py", line 40, in <module>13:36
wiking_    svm = machine("MKLClassification", kernel=combined_kernel, interleaved_optimization=False, svm=as_svm(libsvm))13:36
wiking_NameError: name 'as_svm' is not defined13:36
wiking_i've just moved around that function13:36
wiking_:)))13:36
gf712wiking_: moved around?13:38
gf712is it imported?13:38
wiking_took from line x13:38
wiking_and moved it to line x+113:38
gf712yea I saw the pr13:38
gf712but is it imported?13:38
gf712it is part of the arg list13:39
gf712which is probably handled differently in translate.py13:39
wiking_dunno13:39
gf712and then no import13:39
wiking_but i've just moved the thing arounnd13:39
gf712and no definition13:39
wiking_i dont see how that effects or why should it effect import13:39
wiking_:)13:39
gf712yea, but before it was a function call13:40
gf712on its own13:40
gf712now it is in the arglist13:40
wiking_aaaannd? :)13:40
wiking_i mean if that's the reason13:40
wiking_then its a bug13:40
wiking_but ok13:40
wiking_:)13:40
gf712and I am guessing the import generator does not look unto it13:40
gf712into13:40
wiking_i dont want to fix this bug13:40
gf712that is my guess13:40
gf712haha13:40
gf712let me have a look13:40
gf712I just messed with that part of shogun13:41
gf712wiking_: btw do you know what the status of bool matrix in jblas is?13:42
wiking_imo none existen13:42
wiking_:)13:42
gf712so in java a bool matrix has to be represented as doubles?13:43
gf712such overkill13:43
wiking_yes13:43
gf712from 1 bit to 64 :D13:44
wiking_but i mean jblas is shito13:44
wiking_we should switch to some newer matrix lib13:44
wiking_imo commons-math13:44
gf712why not use jeigen13:44
wiking_or something13:44
gf712or whatever it is called13:44
gf712just need to switch to something that will be around for a while13:44
gf712otherwise have to rewrite the type maps again and again13:45
gf712which sucks13:45
gf712wiking_: there is no import from shogun import as_svm in your case13:48
gf712BUG :D13:48
wiking_i have another problem13:51
wiking_i dont get why this fails on osx13:52
wiking_https://github.com/shogun-toolbox/shogun/pull/4573/files#diff-dfb2492caa57a8d2bbfadf82efb29a9dR33713:52
wiking_i thought the casting to the same type 0 than i would solve this13:53
wiking_but it doesn't13:53
wiking_:S13:53
wiking_i had the error on linux13:56
gf712what is the error message?13:56
wiking_if i used 0 instead 0L13:56
wiking_it's basically that the call is ambigous13:56
wiking_https://dev.azure.com/shogunml/shogun/_build/results?buildId=1186&view=logs&jobId=f9754876-58be-5644-7278-7cc807306c84&taskId=582a8a7a-cf6b-58f0-1740-568c5cebd304&lineStart=523&lineEnd=524&colStart=1&colEnd=113:56
wiking_sorry i cannot copy somehow from the log window :S13:56
wiking_maybe that on osx difftype13:57
gf712and if you do DiffType tmp = 0;14:03
gf712swap(first[i], first[rand->random(tmp, i)])?14:03
gf712oh difftype is std::ptrdiff_t14:04
gf712I'm guess there is implicit casting going on to fit one of those declarations?14:04
gf712in Random.h?14:04
wiking_gf712: yeah random.h14:40
wiking_but what's the diff between14:40
wiking_DiffType tmp = 0;14:40
wiking_and DiffType(0)14:40
wiking_:)14:40
gf712yea, that was wrong14:51
gf712I think the issue is just the implicit casting of std::ptrdiff_t14:52
gf712which makes the call ambiguous14:52
gf712because random doesn't have a signature for std::ptrdiff_t14:52
gf712so tries to cast to one of the others?14:52
gf712and then it can cast any of them -> ambiguous14:52
gf712wiking_: found your bug https://github.com/shogun-toolbox/shogun/pull/460814:56
