DllNotFoundException: libtensorflowlite_c

[fredmouse]

Environment (please complete the following information):

• OS/OS Version: [macOS 11.6] intel Mac
• Source Version: [master/v2.10.0-p1]
• Unity Version: [Unity 2021.3.3.f1]

Describe the bug Couldn't run any example as all prompts the same DllNotFoundException: libtensorflowlite_c exception. I cloned the git with Git-LFS installed, which ended up with almost over 800mb and libtensorflowlite_c.dll of 3mb( I think I didn't miss any files). But I still get this exception on all the examples. Below you can find one of the exception message

DllNotFoundException: libtensorflowlite_c assembly: type: member:(null) TensorFlowLite.InterpreterOptions..ctor () (at Packages/com.github.asus4.tflite/Runtime/InterpreterOptions.cs:62) TensorFlowLite.BaseImagePredictor1[T].CreateOptions (TensorFlowLite.BaseImagePredictor1+Accelerator[T] accelerator) (at Packages/com.github.asus4.tflite.common/Runtime/BaseImagePredictor.cs:104) TensorFlowLite.BaseImagePredictor1[T]..ctor (System.String modelPath, TensorFlowLite.BaseImagePredictor1+Accelerator[T] accelerator) (at Packages/com.github.asus4.tflite.common/Runtime/BaseImagePredictor.cs:98) TensorFlowLite.FaceDetect..ctor (System.String modelPath) (at Assets/Samples/FaceMesh/FaceDetect.cs:48) FaceDetectionSample.Start () (at Assets/Samples/FaceMesh/FaceDetectionSample.cs:27)

@fredmouse Can you check this out? https://github.com/asus4/tf-lite-unity-sample/issues/199#issuecomment-1058950494

On the macOS, please confirm that dylibs are exists at Packages/com.github.asus4.tflite/Plugins/macOS/*.dylib.

I checked every post on this DllNotFoundException topic before posting this issue. I tried these methods like brew install git-lfs and git clone this repository. I also executed "git lfs install" in the cloned folder afterwards. On the other hand, I confirm I have libtensorflowlite_c.dylib and libtensorflowlite_metal_delegate.dylib at Packages/com.github.asus4.tflite/Plugins/macOS/*.dylib.

Hmmm...then I have no idea to solve your error.

I got same error. But I realise my mistake. (My OS is intel Mac[macOS13.4].)

I opened the library in notepad. (Packages/com.github.asus4.tflite/Plugins/macOS/libtensorflowlite_c.dylib) In my case it was a reference file to the Git LFS.

I ran a command (git lfs pull) and the dll entity was downloaded and worked fine.

I hope this helps you.
