Graph-Break Type

Short name describing what triggered the graph break

Unsupported arguments 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 args: {args} and kwargs: {kwargs}. itertools.groupby expects an iterable to group and an optional key function to determine groupings.

Hints

Hints on how to resolve the graph break

• Make sure the arguments to itertools.groupby are correct.
• 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.
