Summary: THCStream was recently moved to ATen by mruberry: https://github.com/pytorch/pytorch/pull/8997. This PR now introduces a guard class that replaces `AutoStream` from `torch/csrc/` and also uses this new stream interface. I had to extend the `CUDAStream` interface with unchecked calls, so that we can reset the stream without throwing an exception in the guard's destructor. colesbury apaszke ezyang Fixes https://github.com/pytorch/pytorch/issues/7800 Pull Request resolved: https://github.com/pytorch/pytorch/pull/9277 Differential Revision: D8865183 Pulled By: goldsborough fbshipit-source-id: 67c9bc09629d92fa5660286b5eec08fde9108cd7
