Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/15967 Codemod generated with clangr shard mode, 25 files per diff, To eliminiate partially initialized Tensor, we split the initialization of local Tensor variables into two steps, first declare un uninitialized Tensor, and call `ReinitializeTensor` to initialize it. motivation: https://github.com/pytorch/pytorch/pull/12407 Reviewed By: smessmer Differential Revision: D13586735 fbshipit-source-id: eae2d79e1107a2e813ce3809e690af4706aaa9ca
