Graph-Break Type

Short name describing what triggered the graph break

Unsupported tensor subclass overridden attribute access

Values or code snippet captured at the break point

{name}

Explanation of why the graph break was triggered

torch.compile only support tracing certain types of overridden tensor subclass attributes

Hints on how to resolve the graph break

Avoid accessing {name} of tensor subclass in torch.compile region
Renaming attribute {name} of type {self.class_type}
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.
