> I tried creating SparseVector with only one non-zero element. But I couldn't create it. Following code causes the problem.
> {code}
> val vec2 = SparseVector.fromCOO(3, (1, 1))
> {code}
> I got a compile error following:
> {code:none}
> Error:(60, 29) overloaded method value fromCOO with alternatives:
>   (size: Int,entries: Iterable[(Int, Double)])org.apache.flink.ml.math.SparseVector <and>
>   (size: Int,entries: (Int, Double)*)org.apache.flink.ml.math.SparseVector
>  cannot be applied to (Int, (Int, Int))
>     val vec2 = SparseVector.fromCOO(3, (1, 1))
>                             ^
> {code}
