QUESTION
I am writing a code to perform kernel K-Means (aka https://en.wikipedia.org/wiki/K-means_clustering, but with a trick). I need to generate data, and as a first simple generator I tried to implement a Gaussian Mixture Model. Here are my code:
...ANSWER
Answered 2017-Aug-07 at 14:15It seems like it's a compiler bug (I suppose in scala macroses as Breeze is using those). You could try to perform total clean in the project (maybe even including .ivy2
folder - this could be a difference between your MacOS and Windows setup) and also update your scala to 2.11.11 (or maybe even 2.12.x)
However, similar issue with Scala 2.11.6 (and something tells me it's inherited in subsequent versions of Scala) wasn't fixed: https://issues.scala-lang.org/browse/SI-9284
So probably, you'll have to repeatedly perform cleaning sometimes or maybe try some other NumPy analogs like: scalala, Nd4j/Ndjs.
It could also help to try another IDE (IDEA/Atom) or try to use "bare" SBT as Eclipse is probably interfering by calling Scala's compiler front-end.

I am using breeze-viz 0.3, but need to use newer version of jfreechart. According to the dependency table https://mvnrepository.com/artifact/org.scalanlp/breeze-viz_2.10/0.3

Answered 2017-Feb-15 at 08:30You see jfreedchart 1.0.13
, but it's another one. If you will have a look onto dependency graph for viz, you will see, that it depends on "jfree" % "jfreechart" % "1.0.13"
, while you want to use "org.jfree" % "jfreechart" % "1.0.19"
, which doesn't intersect with the previous one, since they have different groupId. So, you need to add
