Contributions summary:Guang's commits primarily focus on improving the PyTorch export functionality, specifically for the Dynamo framework. They addressed issues related to incorrect handling of data types during export, added a new experimental operation (`nonzero_static`) to support export, and enhanced the usability of `torch.cond()` by allowing different predicate types. The contributions also involved storing and managing constraints and example inputs as metadata within the graph module to ensure proper runtime checks and improve user experience.
