Graph-Break Type

Short name describing what triggered the graph break

Unsupported key type for itertools.groupby

Context

Values or code snippet captured at the break point

call_function {self} {args} {kwargs}

Explanation

Explanation of why the graph break was triggered

Dynamo does not know how to trace itertools.groupby with key type: {str(type(key))}. We only support grouping keys that are constants (int, float, str, etc.)

Hints

Hints on how to resolve the graph break

• It may be possible to write Dynamo tracing rules for this code. Please report an issue to PyTorch if you encounter this graph break often and it is causing performance issues.
