Graph-Break Type

Short name describing what triggered the graph break

Reconstruction failure (self-referential)

Context

Values or code snippet captured at the break point

str(self)

Explanation

Explanation of why the graph break was triggered

Dynamo tried to reconstruct sourceless variable {self}, but it is self-referential. Dynamo must manually implement reconstruction rules for self-referentiable sourceless variables.

Hints

Hints on how to resolve the graph break

• If Dynamo is attempting to trace a return statement and your code is attempting to return a variable
• that Dynamo cannot reconstruct, then remove it from the return statement.
• Remove the self-reference in the variable. A self-referring list, for example, is l = []; l.append(l).
• Report an issue to PyTorch if you need self-referential reconstrtuction support.
• This graph break may have been caused by an earlier graph break. Resolving the earlier graph break may resolve this one.
