Unable to load the Model by Stream #3462

System information

I have used my model as an embedded resource in one of my projects.


I tried to load the model using Stream and it gives me an error below;

System.ArgumentOutOfRangeException: 'filePath cannot be null or empty
Parameter name: filePath'

Source code / logs

My below code snippet;

var assembly = Assembly.GetExecutingAssembly();
using (var stream = assembly.GetManifestResourceStream(""))
//Create MLContext to be shared across the model creation workflow objects
//Set a random seed for repeatable/deterministic results across multiple trainings.
var mlContext = new MLContext(seed: 1);
Sentiment sampleStatement = new Sentiment { Text = text };
ITransformer trainedModel = mlContext.Model.Load(stream, out var modelInputSchema);

Just an update on this!

If I try to use without using then it works fine. I had to explicitly close the stream.
