System.AccessViolationException on Invoke for TFLite model about emgutf HOT 2 CLOSED

One thing to check is that, in your code:

public void SetInput(float[] values) {
            Marshal.Copy(values, 0, interpreter.Inputs[0].DataPointer, values.Length);
        }

values.Length match the Size of the "interpreter.Inputs[0]".

I would also check and see if any of the objects being used are disposed when the access violation take place.

Given that your model works well for a few thoundsand sucessfull inference, I would thinkg that "objects being used are disposed" is the most likely reason. Sound like garbage collector disposed an object while it is still being used some where in your code.

You were correct, it was a Garbage Collection issue.

Apparently, the Interpreter object does not maintain an active reference to the FlatBufferModel object that is used to instantiate it, even though it does require it. Upon a GC, the model gets disposed and the interpreter no longer works.

I have fixed it on my end, but I would recommend keeping a reference in the Interpreter object as well, to avoid confusion. A GC should, in my humble opinion, not cause AccessViolationExceptions.

Thanks for your help!
