Importing a trained model

Before you import a trained model, you must have exported your model to the ONNX format.

Resource loading

When you have a valid ONNX model, import it into your project; to do this, add the .onnx file to your project's Assets folder. Unity imports the model as an NNModel asset:

See also Visualizing Model.

You can then reference this asset directly in your script as follows:

public NNModel modelAsset;

A model is an asset wrapper and is stored in binary format. You must compile it into a run-time model (of type Model) like this:

public NNModel modelAsset;
private Model m_RuntimeModel;

void Start()
{   
    m_RuntimeModel = ModelLoader.Load(modelAsset);
}    

Runtime loading

You can also use the ModelLoader to directly load the asset from a specified path:

Model model = ModelLoader.Load(modelPath);
