Since 2017, PyTorch has grown far beyond our initial vision. With over 2,400 contributors who have built nearly 154,000 projects using PyTorch as a foundation, PyTorch has become one of the primary platforms for AI research, as well as commercial production use. We’ve seen its impact across industry and academia, from large companies to numerous university courses at Stanford, NYU, EPFL, Oxford, and other academic institutions. As a maintainer of PyTorch, the journey has been extremely fulfilling, with the impact of the project seen in various fields from self-driving cars to healthcare to aerospace.
