Dispose CPU resources

Hi,
I noticed that when I use barracuda worker with WorkerFactory.Type.CSharpBurst or WorkerFactory.Type.CSharp, calling Dispose() does not clean the memory correctly.

var worker = WorkerFactory.CreateWorker(WorkerFactory.Type.CSharp, model);
var inputTensor = new Tensor(texture, channelCount);  // [1, 320, 256, 3]
worker.Execute(inputTensor);
var output = worker.PeekOutput();
...
inputTensor.Dispose();
output.Dispose();
worker.Dispose();

Could you please advice?
Thank you

Could you clarify a bit what you mean by does not clean the memory correctly?
Did you notice memory leaks or high memory usage?

Hello Alexandre,
Correct! I noticed a memory leak.
I have created an application that takes a photo, creates a Texture2D and the Tensor layer then passes it to the model to be classified. After getting the output I run dispose() as you can see, also I DestroyImmediate the Texture2D and I do System.GC.Collect().

I added this: System.GC.GetTotalMemory(false) before and after the function and with each time the memory keeps going up and never clearen. After 5 times repeating the same process I get OutOfMemory error.

Looking forward to hearing from you soon.
