System.EntryPointNotFoundException when loading tflite model in xamarin.ios

[mohaned-abid]

@emgucv I'm trying to add a tflite model to an exsitent xamarin.ios app , I intalled emgu tflite nuget and when I try to load model into a flatbuffermodel object I get an EntryPointNotFoundException , same goes for creating an empty interpreter object

code :
FlatBufferModel x1 = new FlatBufferModel("model.tflite");
or
Interpreter x = new Interpreter();

exception for FlatBufferModel:
System.EntryPointNotFoundException: tfeFlatBufferModelBuildFromBuffer assembly: type: member:(null)
at (wrapper managed-to-native) Emgu.TF.Lite.TfLiteInvoke.tfeFlatBufferModelBuildFromBuffer(intptr,int)

Instructions for using Emgu TF Lite in iOS can be found here:
https://www.emgu.com/wiki/index.php/Emgu_TF_Download_And_Installation#iOS

Are you using Emgu.CV.runtime.ios nuget package or the dlls from the ".zip" commercial release?

@emgucv I only installed this one : https://www.nuget.org/packages/EMGU.TF.LITE/ , I thought that I can test that the integration works with my model before bying the comercial lisence.

also why would I need "Emgu.CV.runtime.ios " I thought I would only need emgu tf lite ? do you mean "Emgu.TF.Lite.runtime.ios" ?

also about the size of the dll , what is the average range for the size in case of only arm64 support
thanks for the help

You will need one of the Emgu.TF.Lite.runtime.{platform} package depends on the os your are using. Detail can be found here:

The runtime nuget pacakge contains the native Tensorflow Lite binary in C/C++. The Emgu.TF.Lite nuget packages only contains the C# interface to call into those tensorflow lite functions.

An yes, I mean Emgu.TF.Lite.runtime.ios package from the commercial release. (not Emgu.CV.runtime.ios)
