Summary:
maybe this is too much info, but it's difficult to go through old draft export reports where the stack trace is out of sync with the current codebase. Data-dependent errors now look like:
```
2. Data dependent error.
When exporting, we were unable to evaluate the value of `u306`.
This occurred at the following stacktrace:
File /data/users/pianpwk/fbsource/buck-out/v2/gen/fbcode/78204cab86e8a0fb/sigmoid/inference/ts_migration/__pt2i_readiness_main__/pt2i_readiness_main#link-tree/caffe2/torch/fb/training_toolkit/common/proxy_module_thrift/embedding_bag_proxy.py, lineno 109, in _forward_impl:
`if offsets[-1] > len(input):`
As a result, it was specialized to evaluate to `261`, and asserts were inserted into the graph.
Please add `torch._check(...)` to the original code to assert this data-dependent assumption.
Please refer to https://docs.google.com/document/d/1kZ_BbB3JnoLbUZleDT6635dHs88ZVYId8jT-yTFgf3A/edit#heading=h.boi2xurpqa0o for more details.
```
This would be even more helpful for reports on torch-packaged models, but that requires some more work on PT2I-specific stack trace processing
