TorchVision Library
Starting from 1.9, users can use the TorchVision library on their iOS/Android apps. The Torchvision library contains the C++ TorchVision ops and needs to be linked together with the main PyTorch library for iOS, for Android it can be added as a gradle dependency. This allows using TorchVision prebuilt MaskRCNN operators for object detections and segmentation. To learn more about the library, please refer to our tutorials and demo apps.
