I’ve exported Pytorch model for android and trying to load Module I’ve got the following error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{org.pytorch.demo/org.pytorch.demo.vision.FrameProcessingActivity}: com.facebook.jni.CppException: empty not implemented for TensorTypeSet(VariableTensorId, CUDATensorId) (empty at aten/src/ATen/Functions.h:3679)
(no backtrace available)


whole stack trace is:
