This example produces exceptions when using the latest version of the Infer.Net libraries (v.2.4). Initially the following line throws a compilation exception...
Variable<Vector> w = Variable.Random(new VectorGaussian(new Vector(3), PositiveDefiniteMatrix.Identity(3))).Named("w");
and needs to be changed to
Variable<Vector> w = Variable.Random(new VectorGaussian(Vector.Zero(3), PositiveDefiniteMatrix.Identity(3))).Named("w");
This then generates the following runtime exception:
Test method InferenceTests.UnitTest1.Test2 threw exception:
System.ArgumentException: VariableArray<Vector> x cannot be indexed by index1. Perhaps you omitted index1 as an argument to the constructor?
Parameter name: index

Hoping someone can suggest a fix for this please.
Thanks, Chris
