Graph-Break Type

Short name describing what triggered the graph break

Untraceable C tp_hash

Values or code snippet captured at the break point

hash_impl {self}

Explanation of why the graph break was triggered

{cls.name} defines a C hash that Dynamo cannot trace into.

Hints on how to resolve the graph break

Use torch._dynamo.allow_c_slot({cls.name}) to
register it as safe if its slots are pure and
deterministic.
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.
