Question Dynamically loading Onnx file and setting as the model for an Agent

I have a .onnx file from a trained model that's stored on the application persistentpath. I want to load it at runtime and set it as the model for an Agent. Now, the Agent expects a NNModel in its SetModel method. This is what I've tried

Code (CSharp):

1.  
2. var modelPath = NNHelper.GetOnnxPath(Species, selectedBrain.Brain);
3. var modelData = File.ReadAllBytes(modelPath);
4. NNModel model = ScriptableObject.CreateInstance<NNModel>();
5. model.modelData = ScriptableObject.CreateInstance<NNModelData>();
6. model.modelData.Value = modelData;
7. GetComponent<FishAgent>().SetModel("Fishy", model);

This results in the NotSupportedException: Format version not supported: 242 error since Barracuda doesn't support Onnx files apparently. Online I've read some people have used the ONNXConverter, however, that converts the byte[] to a Model, where a byte[] is required for the modelData.Value.

Any suggestions?

 

Fixed it. If anyone wants to know, take a look at the ONNXModelImporter.
