I made a test script which looks like this:
[icode]import arrayfire as af
def test_Array(array):
    return af.min(array)
[/icode]

My C++ code looks like this:
[icode]int Interpreter::testArray()
{
    af::array myArray = af::seq(5, 10, 1);

    // Create arrayfire array and set 
    PyObject* afArray = createObject("arrayfire", "Array");

    // The 'arr' attribute is holding the af_array reference
    PyObject* attr = PyObject_GetAttrString(afArray, "arr");

    // Build an attribute object with our AF array reference
    PyObject* capsule = PyCapsule_New(myArray.get(), "c_void_p", nullptr);
    PyObject* attrObj = createObject("ctypes", "c_void_p", Py_BuildValue("(O)", capsule));

    // Set 'arr'
    int results = PyObject_SetAttr(afArray, PyUnicode_FromString("arr"), attrObj);

    // Call test function
    PyObject *pFunc = PyObject_GetAttrString(m_module, "test_Array");
    PyObject *pArgs = Py_BuildValue("(O)", afArray);

    if (pFunc)
    {
        PyObject *pResult = PyObject_CallObject(pFunc, pArgs);

        if (pResult)
        {
            float res = PyFloat_AsDouble(pResult);
            qDebug() << "Array min: " << res;
        }
        else
        {
            getError();
        }
        Py_XDECREF(pResult);
    }

    //...
    return 0;
}

PyObject* Interpreter::createObject(const QString& module, const QString& name, PyObject* args /*= nullptr*/)
{
    PyObject* pName = nullptr;
    PyObject* pModule = nullptr;
    PyObject* pDict = nullptr;
    PyObject* pClass = nullptr;
    PyObject* pInstance = nullptr;

    // Build the name object
    pName = PyUnicode_FromString(module.toLatin1());

    // Load the module object
    pModule = PyImport_Import(pName);

    if (!pModule)
    {
        qDebug() << "Unknown module name";
        return pInstance;
    }

    // pDict is a borrowed reference
    pDict = PyModule_GetDict(pModule);

    // Build the name of a callable class
    pClass = PyDict_GetItemString(pDict, name.toLatin1());

    // Create an instance of the class
    if (PyCallable_Check(pClass))
    {
        pInstance = PyObject_CallObject(pClass, args);
    }
    else
    {
        qDebug() << "Cannot instantiate the Python object";
    }

    return pInstance;
}
