Worked on the pytorch/pytorch repository to enhance developer guidance around dynamic and compile usage by clarifying documentation for torch._dynamo.mark_dynamic() in conjunction with torch.compile(). Focused on aligning the API documentation with actual runtime behavior, a warning was added to emphasize that torch._dynamo.mark_dynamic() should not be called within a model’s forward method when using torch.compile(). This update, implemented using Python and Markdown, aimed to reduce the risk of misuse and improve onboarding for new contributors. The work demonstrated attention to detail in API design and documentation, ensuring that official guidance accurately reflects PyTorch’s runtime constraints and best practices.
