Get Started

Get Started with PyTorch ExecuTorch

PyTorch’s edge specific library is ExecuTorch and is designed to be lightweight, very performant even on devices with constrained hardware such as mobile phones, embedded systems and microcontrollers.

ExecuTorch relies heavily on PyTorch core technologies such as torch.compile and torch.export, and should be very familiar to anyone who has used PyTorch in the past.
