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) Generator)contextmanager) dataclassfield)AnyCallablec@seZdZdZdZdZdZdS)CallbackTriggerN)__name__ __module__ __qualname__ZDYNAMOZ LAZY_BACKWARDZTRITON_AUTOTUNINGZCUDAGRAPH_RECORDINGrr\/home/www/facesmatcher.com/frenv_anti/lib/python3.10/site-packages/torch/_dynamo/callback.pyr$s rc@seZdZUeed<eed<dS) CallbackArgsZcallback_trigger compile_idN)r rrr__annotations__strrrrrr/s  rc @sTeZdZUeedZeeegdfed<eedZ eeegdfed<eddddZ e ed<ee j ddd Ze j ed <d eegdfd eegdffd dZd eegdfd eegdffddZd eegdfd dfddZd eegdfd dfddZded dfddZded dfddZededed edeeffddZd ddZdS)!CompilationCallbackHandler)default_factoryNstart_callbacks end_callbacksrF)defaultinitrepr6_CompilationCallbackHandler__pending_callbacks_counter)rrr;_CompilationCallbackHandler__pending_callbacks_counter_lockcallbackreturncC|j||S)z Register a callback function to be called when the compilation starts.
