Graph-Break Type

Short name describing what triggered the graph break

collections.deque() with bad iterable argument

Values or code snippet captured at the break point

args={args}, kwargs={kwargs}

Explanation of why the graph break was triggered

Call to collections.deque() has an iterable argument that Dynamo cannot convert to a list.

Hints on how to resolve the graph break

Use a simpler sequence type that Dynamo can convert to a list
(e.g. list, tuple, list iterator, etc.)
Your code may result in an error when running in eager. Please double check that your code doesn’t contain a similar error when actually running eager/uncompiled. You can do this by removing the torch.compile call, or by using torch.compiler.set_stance("force_eager").
