Graph-Break Type

Short name describing what triggered the graph break

Dynamo recompile limit exceeded

Context

Values or code snippet captured at the break point

Limit type: {limit_type}

Explanation

Explanation of why the graph break was triggered

Dynamo attempted to recompile the code object too many times, exceeding the {limit_type} cache size limit (currently set to {getattr(config, limit_type)}). Excessive recompilations can degrade performance due to the compilation overhead of each recompilation.

Hints

Hints on how to resolve the graph break

• To monitor recompilations, enable TORCH_LOGS=recompiles.
• If recompilations are expected, consider
• increasing torch._dynamo.config.{limit_type} to an appropriate value.
• See {troubleshooting_url} for tips on dealing with recompilations.
