Thomas FOURNIER updated FLINK-4850:
-----------------------------------
Description:
It seems that evaluate operation is defined for Vector and not LabeledVector.
It impacts QuickStart guide for FlinkML when using SVM.
1- We need to update the documentation as follows:
val astroTest:DataSet[(Vector,Double)] = MLUtils
.readLibSVM(env, "src/main/resources/svmguide1.t")
.map(l => (l.vector, l.label))
val predictionPairs = svm.evaluate(astroTest)
2- Update code such that LabeledVector can be used with evaluate method
was:
