grecocd | how do I free the memory of variables and SGMatrices in the destructor? I’ve tried SG_UNREF, SG_FREE and delete | 15:40 |
---|---|---|
grecocd | i get different errors evert time | 15:41 |
grecocd | I also get this error when I use SG_ERROR: error: use of undeclared identifier 'io' SG_ERROR | 15:41 |
lisitsyn | grecocd: sgmatrix is kind of automatic in that sense | 15:44 |
grecocd | what about int32_t variables? | 15:44 |
grecocd | does anybody know why I get the error: use of undeclared identifier 'io' SG_ERROR when i se SG_ERROR, even though i have included SGIO.h? | 15:49 |
grecocd | use* | 15:49 |
-!- NonResponsive [~NonRespon@resnetpub1.nsms.ox.ac.uk] has quit [Read error: Operation timed out] | 15:52 | |
lisitsyn | grecocd: what's with int32_t? | 15:52 |
lisitsyn | grecocd: try SG_SERROR | 15:53 |
lisitsyn | you are probably out of any class so SG_SERROR is needed | 15:53 |
lisitsyn | when you are inside of a class you use SG_ERROR | 15:53 |
grecocd | lisitsyn: is there a way i can free the memory of them or is that not needed? | 15:53 |
lisitsyn | free single int32_t variable or what? | 15:53 |
grecocd | alright, let me try it | 15:53 |
grecocd | yes | 15:54 |
grecocd | of a single int32_t variable | 15:54 |
lisitsyn | int32_t a; | 15:54 |
lisitsyn | like that? | 15:54 |
grecocd | yes | 15:54 |
lisitsyn | why to free them? | 15:54 |
lisitsyn | they are not allocated on heap | 15:54 |
grecocd | idk, i was asked how the memory was freed from my class, but you said that SGMatrices already do that, so thats the only other thing i can free | 15:55 |
lisitsyn | int32_t = int | 15:55 |
lisitsyn | so nothing special here | 15:55 |
grecocd | alright, thanks! | 15:56 |
grecocd | one more thing! | 15:56 |
grecocd | why do i get this error: error: no viable overloaded '=' | 15:56 |
lisitsyn | depends what do you assign | 15:56 |
grecocd | i have a SGMatrix<float64_t> that is going to receive the value of the return of nearest_neighbors() | 15:57 |
grecocd | nearst_neighbors() returns a SGMatrix as well | 15:57 |
-!- Rho__ [~rho@217.55.203.184] has quit [Quit: Leaving] | 15:59 | |
lisitsyn | grecocd: you can assign sgmatrix to sgmatrix so something else | 16:11 |
grecocd | i can’t you mean? | 16:12 |
grecocd | actually i just saw that nearest_neighbors() returns SGMatrix<index_t> | 16:19 |
lisitsyn | yeah that's ok | 16:20 |
grecocd | its ok for to assign an SGMatrix<index_t> to a SGMatrix<float64_t>? | 16:21 |
-!- NonResponsive [~NonRespon@client-7-218.eduroam.oxuni.org.uk] has joined #shogun | 16:32 | |
grecocd | I have a SGMatrix<index_t> that I need to return, but I need to return an SGMatrix<float64_t>, how do I do that conversion? | 16:43 |

sonne|work | grecocd: you have to create a new one and manually fill in the values | 17:07 |
grecocd | alright thanks | 17:09 |
grecocd | one more question. i made my class inherit from another class to have access to a protected method but im getting: error: no matching constructor for initialization of 'CKDE' | 17:09 |
grecocd | i have made the constructor CKDE(): KNN() , whats wrong here? | 17:10 |
@wiking | grecocd: why woould you inherit KDE from KNN? | 17:10 |

grecocd | wiking: because I need to use the train_machine() method from KNN, and it is protected | 17:52 |

@wiking | grecocd: no... that is actually inherited from CMachine... | 18:03 |
@wiking | grecocd: i really suggest you to first read about class hierarchy in the doxygen | 18:04 |
@wiking | grecocd: http://shogun-toolbox.org/doc/en/latest/classshogun_1_1CMachine.html | 18:04 |
@wiking | grecocd: and for the reference i'm really not saying that KDE should be inherited from CMachine... i'm just saying that KNN is for sure not the right inheritance... | 18:05 |
@wiking | especially if your only reason to do that is because train_machine... | 18:05 |
grecocd | wiking: thanks, ill check up on that | 18:05 |
@wiking | grecocd: and this could be as well of help: http://www.cplusplus.com/reference/ | 18:06 |
