[Bug] ModuleNotFoundError: No module named 'torch._C._nativert' with recent PyTorch nightly

[dingandchen]

I am encountering a ModuleNotFoundError when trying to run the dynamobench/torchbench.py benchmark with a recent PyTorch nightly build. It seems the internal API torch._C._nativert has been removed or changed in the latest PyTorch versions, causing the import in common.py to fail.

• I also meet same error in pytorch 2.8.0. ModuleNotFoundError: No module named 'torch._C._nativert'; 'torch._C' is not a package
