C'est l'erreur que je reçois dans android lors du chargement du modèle.
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.example.cataractdetectionapp/com.android.example.cataractdetectionapp.InferenceActivity}:
com.facebook.jni.CppException: Could not run 'aten::empty_strided' with arguments from the 'CUDA' backend.
This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build).
If you are a Facebook employee using PyTorch on mobile, please visit https://fburl.com/ptmfixes for possible resolutions.
'aten::empty_strided' is only available for these backends:
[CPU, Vulkan, BackendSelect, Python, Named, Conjugate, Negative, ADInplaceOrView, AutogradOther, AutogradCPU, AutogradCUDA,
AutogradXLA, AutogradLazy, AutogradXPU, AutogradMLC, UNKNOWN_TENSOR_TYPE_ID, Autocast, Batched, VmapMode].

J'ai utilisé le code ci-dessous pour charger le module:
Module module = LiteModuleLoader.load(assetFilePath(getApplicationContext(), "Model.ptl"));
Les dépendances que j'utilise pour Pytorch sont comme suit:
implementation 'org.pytorch:pytorch_android_lite:1.10.0'
implementation 'org.pytorch:pytorch_android_torchvision:1.10.0'
