Import a model file

To import an ONNX model file into your Unity project, drag the .onnx file from your computer into the Assets folder of the Project window.

If your model has external weights files, put them in the same directory as the model file so that Inference Engine imports them automatically.

For more information on supported model formats, refer to Supported models.

Create a runtime model

To use an imported model in your scene, use ModelLoader.Load to create a runtime Model object.

using UnityEngine;
using Unity.InferenceEngine;

public class CreateRuntimeModel : MonoBehaviour
{
    public ModelAsset modelAsset;
    Model runtimeModel;

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

After the model is loaded, you can create an engine to run a model.
