Lite Interpreter version number does not match.

Caused by: com.facebook.jni.CppException: Lite Interpreter version number does not match. The model version must be between 3 and 7 but the model version is 8 () Exception raised from parseMethods at ../torch/csrc/jit/mobile/import.cpp:317 (most recent call first): (no backtrace available)

Did you find a solution ? I have the same error with the ObjectDetection demo

@supremassi try old version of python and PyTorch

@ahmadbajwa8282 Hello. Which version of python and PyTorch versions helped you to fix the issue with Lite Interpreter version? Thank you very much in advance!

Here is what you can refer to Convert between different model versions.

`dependencies { ...

implementation 'org.pytorch:pytorch_android_lite:1.13.1'
implementation 'org.pytorch:pytorch_android_torchvision_lite:1.13.1'

}` This works for me.
