I'm trying to use MS's onnx runtime packages on a project for the ML2. I'm using ORT becuase barracuda doesn't work for my model type. The code works in Unity, but the session (create by InferenceSession(), throws a null exception when I try to use Run(). This only happens on device and not in the Unity editor. Any ideas?

Specifically at this line:  
results = session.Run(inputs).First().AsEnumerable();

I get this exception:  
Object Reference Not Set To An Instance Of An Object

Had a thought. It may be the the onnx file isnt being loaded propely. What directory does the file need to be in to be loaded?

Unfortunately, we are not familiar with this solution and recommend asking on the MS's Onnx Runtime Package's github.

You can also test if the issue is specific to Magic Leap 2 or Android, by testing the application on the Android Studio Simulator. Simply create a Unity 2D application that targets x86\_64 and deploy it to the virtual device. Make sure the device is configured for ( Android 10, x86\_64 , No Google Play services). If your application runs as expected, you can then deploy the 2D app to your headset and see if the issue persists.

OK. Is there a recommended way to run an SVM model on the ML2?

I'm not sure I understand, SVM model?
