TorchDynamo captures PyTorch programs safely using Python Frame Evaluation Hooks and is a significant innovation that was a result of 5 years of our R&D into safe graph captureĪOTAutograd overloads PyTorch’s autograd engine as a tracing autodiff for generating ahead-of-time backward traces. Underpinning pile are new technologies – TorchDynamo, AOTAutograd, PrimTorch and TorchInductor. pile is a fully additive (and optional) feature and hence 2.0 is 100% backward compatible by definition. We believe that this is a substantial new direction for PyTorch – hence we call it 2.0. Today, we announce pile, a feature that pushes PyTorch performance to new heights and starts the move for parts of PyTorch from C++ back into Python. PyTorch 2.x: faster, more pythonic and as dynamic as ever

There is still a lot to learn and develop but we are looking forward to community feedback and contributions to make the 2-series better and thank you all who have made the 1-series so successful.

We are able to provide faster performance and support for Dynamic Shapes and Distributed.īelow you will find all the information you need to better understand what PyTorch 2.0 is, where it’s going and more importantly how to get started today (e.g., tutorial, requirements, models, common FAQs). PyTorch 2.0 offers the same eager-mode development and user experience, while fundamentally changing and supercharging how PyTorch operates at compiler level under the hood.

PyTorch’s biggest strength beyond our amazing community is that we continue as a first-class Python integration, imperative style, simplicity of the API and options. Over the last few years we have innovated and iterated from PyTorch 1.0 to the most recent 1.13 and moved to the newly formed PyTorch Foundation, part of the Linux Foundation. Introducing PyTorch 2.0, our first steps toward the next generation 2-series release of PyTorch.
