Cannot find the ONNX file specified using WinML

Question

I am trying to load an ONNX model using WinML, with the following code:

private async Task InitializeModelAsync()
{
    var path = @"ms-appx:///Assets/FER-Emotion-Recognition.onnx";
    var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri(path));
    model = await CNTKGraphModel.CreateCNTKGraphModel(file);
}

The project compiles OK, but during run-time I am getting a System.IO.FileNotFoundException:

The system cannot find the file specified.

I double checked but the file is indeed in the right folder. What did I do wrong?

Answer 1

Right click on your onnx file, go to the Properties panel and set its Build Action to Content.

Then, set the Copy to Output Directory to Copy if newer.
