采集代码如下：

 

 # 配置采集参数 

    experimental_config = torch_npu.profiler._ExperimentalConfig( 

        export_type=torch_npu.profiler.ExportType.Text, 

        aic_metrics=torch_npu.profiler.AiCMetrics.PipeUtilization,

        data_simplification=False 

    ) 

    with torch_npu.profiler.profile( 

            activities=[torch_npu.profiler.ProfilerActivity.CPU, torch_npu.profiler.ProfilerActivity.NPU], 

            schedule=torch_npu.profiler.schedule(wait=0, warmup=1, active=1, repeat=1, skip_first=0), 

            on_trace_ready=torch_npu.profiler.tensorboard_trace_handler("./result_{}".format(epoch)), 

            record_shapes=True, 

            profile_memory=True, 

            with_stack=True, 

            with_flops=False, 

            with_modules=False, 

            experimental_config=experimental_config 

    ) as prof: 

        # for i, (images, target) in enumerate(train_loader)及其包含的代码向后缩进 

        for i, (images, target) in enumerate(train_loader): 

......

运行日志如下：
