KNN iconvertible problem

[ulv...@gmail.com]

Hello, dear friends

I have a big dataset, I want to teach him on Accord.net. I used the knn(KNearestNeighbors) method, I got a trained bin file, but now the problem is that when I run it, an error occurs that is not searcheble relative to Accord.Net anywhere.

var tree = Serializer.Load<KNearestNeighbors>(Path.Combine(basepath, "weightedEuclidean.bin"));

I call the trained method, save to a variable and the following error appears.

object should implement iconvertible.

Thank you.
