Extension# This section provides insights into extending PyTorch’s capabilities. It covers custom operations, frontend APIs, and advanced topics like C++ extensions and dispatcher usage. All PyTorch Custom Operators Landing Page This is the landing page for all things related to custom operators in PyTorch. Extending-PyTorch,Frontend-APIs,C++,CUDA Custom Python Operators Create Custom Operators in Python. Useful for black-boxing a Python function for use with torch.compile. Extending-PyTorch,Frontend-APIs,C++,CUDA Custom C++ and CUDA Operators How to extend PyTorch with custom C++ and CUDA operators. Extending-PyTorch,Frontend-APIs,C++,CUDA Custom Function Tutorial: Double Backward Learn how to write a custom autograd Function that supports double backward. Extending-PyTorch,Frontend-APIs Custom Function Tutorial: Fusing Convolution and Batch Norm Learn how to create a custom autograd Function that fuses batch norm into a convolution to improve memory usage. Extending-PyTorch,Frontend-APIs Custom C++ and CUDA Extensions Create a neural network layer with no parameters using numpy. Then use scipy to create a neural network layer that has learnable weights. Extending-PyTorch,Frontend-APIs,C++,CUDA Registering a Dispatched Operator in C++ The dispatcher is an internal component of PyTorch which is responsible for figuring out what code should actually get run when you call a function like torch::add. Extending-PyTorch,Frontend-APIs,C++ Extending Dispatcher For a New Backend in C++ Learn how to extend the dispatcher to add a new device living outside of the pytorch/pytorch repo and maintain it to keep in sync with native PyTorch devices. Extending-PyTorch,Frontend-APIs,C++ Facilitating New Backend Integration by PrivateUse1 Learn how to integrate a new backend living outside of the pytorch/pytorch repo and maintain it to keep in sync with the native PyTorch backend.
