How to use .pth model in iOS App

Hello All, Hope you doing well with your loving ones!!

Want to use the PoseNet 3D model in iOS app. For which decided to go for https://github.com/Daniil-Osokin/lightweight-human-pose-estimation-3d-demo.pytorch . For which we can download the Pre trained Model from https://drive.google.com/file/d/1niBUbUecPhKt3GyeDNukobL4OQ3jqssH/view.

Here I have downloaded the model which having .pth as extension. As per the Pytorch ‘Hello World’
.pt is required. when using ‘LibTorch’ pod.

as per apple it should be converted to .mlmodel to use the native APIs.

But I am not able to proceed anyway. as neither able to convert the .pth model to .pt nor .mlmodel

Any help will be appreciated

Thanks & Regards
