This task is part of a bigger effort to migrate Pytorch from Mypy to Pyre. The goal of this task for you is to gain comfort with the Python type system and the types of errors Pyre gives. Future Pysa project work and debugging builds on this foundation.
Fix the Pyre type checking errors in torch/_VF.pyi:
