Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/12768 Note: DefaultTensorOptions no longer fits in 64-bits. I kept functions that take ScalarType as input to minimize changes for now. Reviewed By: ezyang Differential Revision: D10419671 fbshipit-source-id: 9cc8c5982fde9ff243e03d55c0c52c2aa2c7efd8
