    Hi John, 

    Thanks for your reply

    how do I convert this array here to a SharedVariableArray?

    VariableArray<Vector> phi = Variable.Array<Vector>(topicsNumRange);

    Hi Freddy

    Assuming you split the data into NumChunks chunks, the code would look something like this:

    using DirichletArray=DistributionRefArray<Dirichlet, Vector>;
    DirichletArray phiPrior =  new DirichletArray(new Dirichlet(beta));
    Range TopicsNum = new Range(K);
    SharedVariableArray    <Vector> sharedPhi = SharedVariable<Vector>.Random(TopicsNum, phiPrior);
    Model = new Model(NumChunks);
    VariableArray<Vector> phi = sharedPhi .GetCopyFor(Model)

    Then use phi as before in your model. You will have to explicitly do several passes, looping over the chunks as shown in the documented scalar example.
