Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/71291 This commit removes torch::lazy::convertShapes since it's no longer used. In addition, it replaces a numel logic within LTCTensorImpl. Test Plan: ./build/bin/test_lazy CI in lazy_tensor_staging branch Reviewed By: wconstab Differential Revision: D33575084 Pulled By: alanwaketan fbshipit-source-id: b104ef39fd552822e1f4069eab2cb942d48423a6
