I made C++ implementation 469 of Mask R-CNN 81 with PyTorch C++ frontend. The code is based on PyTorch implementations from multimodallearning 29 and Keras implementation from Matterport 17 . Project was made for educational purposes and can be used as comprehensive example of PyTorch C++ frontend API. Besides regular API you will find how to: load data from MSCoco dataset, create custom layers, manage weights across language boundaries(Python to C++). Feel free to ask a questions.
