Args: tag (str | None): Optional tag used in logs/prints. measure_cpu (bool): Whether to measure CPU time (using `time`). Default: `True`. measure_cuda (bool): Whether to measure CUDA time (using CUDA events). Default: `True`. unit (str | None): Optional time unit. Must be either "s" (seconds), "ms" (microseconds), "us" (nanoseconds), or None (format automatically based on value). debug (bool): Whether to log results in debug mode instead of info. Default is False. Examples: ```python with Timer(measure_cpu=True, measure_cuda=True, unit="ms"): model(x) ``` ```python @Timer(measure_cpu=True, measure_cuda=True, unit="ms") def func(x): return model(x) ``` NTFtag measure_cpu measure_cudardebugcCs||_||_d|_d|_d|_d|_d|_d|_d|_d|_ |dur$dn||_ ||_ |j dur=|j dvr=t d|j d||_ dS)NFrunknown)rrrrr)r"r#measured cpu_time_us cuda_time_usbusycpu_time_startcuda_start_eventcuda_end_event cuda_streamr!rrr$)selfr!r"r#rr$rrr__init__os zTimer.__init__msgcCs"|jr t|dSt|dSN)r$rinfo)r.r0rrr_logsz Timer._logcCs |dSr1)startr.rrr __enter__s zTimer.__enter__cCs||dSr1)endreport)r.exc_type exc_value tracebackrrr__exit__s zTimer.__exit__funcrcstfdd}|S)Ncs*|i|}|Sr1)r4r7r8)argskwargsresultr=r.rrwrappers zTimer.__call__..wrapperr)r.r=rBrrAr__call__szTimer.__call__c Cs|jr|jr|d|jd|d|dS|jr.|d|jd|dS|jrA|d|jd|dSt)z' Reports measurements. zTime spent on z: CPU: z, CUDA: z: zCUDA time spent on N)r"r#r3r!get_cpu_time_strget_cuda_time_strrr5rrrr8s *  z Timer.reportcCV|js td|jd|jstd|jdurtd|jdus#Jt|j|jdS)z/ Returns CPU time measurement.
