HalfMoon example on Quantum Hardware about quantum

Same issue - have you found a solution?

Well, if it is still actual - I tried to pass arrays as 1-dimensional. I parsed them with this:

    parameter_starting_points = [
        [0.060057, 3.00522, 2.03083, 0.63527, 1.03771, 1.27881, 4.10186, 5.34396],
        [0.586514, 3.371623, 0.860791, 2.92517, 1.14616, 2.99776, 2.26505, 5.62137],
        [1.69704, 1.13912, 2.3595, 4.037552, 1.63698, 1.27549, 0.328671, 0.302282],
        [5.21662, 6.04363, 0.224184, 1.53913, 1.64524, 4.79508, 1.49742, 1.545]
    ]

    # Submit the Q# operation to Azure Quantum
    trainingVectors=data['TrainingData']['Features']
    trainingLabels=data['TrainingData']['Labels']
    initialParameters=parameter_starting_points
    
    data1 = [row[0] for row in trainingVectors]
    data2 = [row[1] for row in trainingVectors]
    
    _1 = [row[0] for row in initialParameters]
    _2 = [row[1] for row in initialParameters]
    _3 = [row[3] for row in initialParameters]
    _4 = [row[4] for row in initialParameters]

and then just passed them with this job

(parameters, bias) = qsharp.azure.execute(TrainHalfMoonModel, data1=data1, data2=data2, trainingLabels=trainingLabels, _1=_1, _2=_2, _3=_3, _4=_4, shots=100, jobName="Train", timeout=18000)


In q# I just combined them back

    operation TrainHalfMoonModel(
        data1 : Double[],
        data2 : Double[],
        trainingLabels : Int[],
        _1 : Double[],
        _2 : Double[],
        _3 : Double[],
        _4 : Double[],
    ) : (Double[], Double) {
        let trainingVectorsArray = Zipped(data1, data1);
        let trainingVectors = Mapped(CombineFunction, trainingVectorsArray);

        let initialParametersArray = Zipped4(_1, _2, _3, _4);
        let initialParameters = Mapped(CombineFunction4, initialParametersArray);
        
        ..........................

And few functions:

    function CombineFunction(a: Double, b: Double): Double[] {
        return [a, b];
    }

    function CombineFunction4(a: Double, b: Double, c: Double, d: Double): Double[] {
        return [a, b, c, d];
    }
