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.)
Dynamo has detected that tracing the code will 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.
