It implements a thread-safe system for registering, managing and executing callbacks that run at the start and end of TorchDynamo compilations. Key features include: - Registration and deregistration of compilation callbacks - Thread-safe callback handling with proper locking mechanisms - Prevention of duplicate callback execution when configured - Decorator utilities for easy callback registration - Context manager for controlled callback lifecycle The module centers around the CompilationCallbackHandler class which maintains separate lists for start and end callbacks, manages their execution order, and ensures thread-safety. Utility decorators @on_compile_start and @on_compile_end provide a convenient way to register compilation hooks. Example usage: @on_compile_start def my_start_callback(): print("Starting compilation") @on_compile_end def my_end_callback(): print("Compilation complete") N)Callable Generator)contextmanager) dataclassfield)Anyc$\rSrSrSrSrSrSrSrg)CallbackTrigger$N) __name__ __module__ __qualname____firstlineno__DYNAMO LAZY_BACKWARDTRITON_AUTOTUNINGCUDAGRAPH_RECORDING__static_attributes__rS/home/mande/repo/quber/.venv/lib/python3.13/site-packages/torch/_dynamo/callback.pyr r $s FMrr c*\rSrSr%\\S'\\S'Srg) CallbackArgs/callback_trigger compile_idrN)rrrrr __annotations__strrrrrrr/s %%Orrc \rSrSr%\"\S9r\\\/S4\ S'\"\S9r \\\/S4\ S'\"SSSS9r \ \ S '\"\ RSSS 9r\ R\ S 'S \\/S4S \\/S44SjrS \\/S4S \\/S44SjrS \\/S4S S4SjrS \\/S4S S4SjrS\S S4SjrS\S S4Sjr\S\S\S \S\\44Sj5rSSjrSrg)CompilationCallbackHandler5)default_factoryNstart_callbacks end_callbacksrF)defaultinitrepr6_CompilationCallbackHandler__pending_callbacks_counter)r&r*r+;_CompilationCallbackHandler__pending_callbacks_counter_lockcallbackreturnc<URRU5 U$)z Register a callback function to be called when the compilation starts.
