Graph-Break Type

Short name describing what triggered the graph break

torch._dynamo.step_unsupported() with empty checkpoint

Values or code snippet captured at the break point

Explanation of why the graph break was triggered

traced torch._dynamo.step_unsupported(), but there is no checkpoint to step_graph_break from. This graph break is used for debugging only.

Hints on how to resolve the graph break

Remove the torch._dynamo.step_unsupported() call.
Include at least one checkpoint: (1) include at least 2 ops and (2) make sure there is some
line of code that is not in a try/with block, and has an empty Python stack.
This is likely to be a Dynamo bug. Please report an issue to PyTorch.
