 If you rely on the default affinity distribution, you can avoid calling <code>InferenceEngine::Core::QueryNetwork</code> and just call <code>InferenceEngine::Core::LoadNetwork</code> instead:

 Attributes are properties of nodes in the computational graph, which will be stored when the model is serialized to a file. However, there can be additional properties of nodes, which are only important during the execution of a graph. An example of such a property is `affinity`, which determines which operation will be executed on which hardware in a heterogeneous environment. You can get and set runtime information by using the `get_rt_info` method of a node.
