RecordEvent¶

class paddle.profiler. RecordEvent ( name: str, event_type: TracerEventType = TracerEventType.UserDefined ) [源代码] ¶

该接口用于用户自定义打点，记录某一段代码运行的时间。

参数¶

name (str) - 记录打点的名字。

event_type (TracerEventType，可选) - 可选参数，默认值为TracerEventType.UserDefined。该参数预留为内部使用，最好不要指定该参数。

代码示例¶

           import paddle
 import paddle.profiler as profiler
 # method1: using context manager
 with profiler.RecordEvent("record_add"):
     data1 = paddle.randn(shape=[3])
     data2 = paddle.randn(shape=[3])
     result = data1 + data2
 # method2: call begin() and end()
 record_event = profiler.RecordEvent("record_add")
 record_event.begin()
 data1 = paddle.randn(shape=[3])
 data2 = paddle.randn(shape=[3])
 result = data1 + data2
 record_event.end()

         

注解

RecordEvent只有在性能分析器处于RECORD状态才会生效。

方法¶

begin()¶

记录开始的时间。

代码示例

            import paddle
 import paddle.profiler as profiler
 record_event = profiler.RecordEvent("record_sub")
 record_event.begin()
 data1 = paddle.randn(shape=[3])
 data2 = paddle.randn(shape=[3])
 result = data1 - data2
 record_event.end()

          

end()¶

记录结束的时间。

代码示例

            import paddle
 import paddle.profiler as profiler
 record_event = profiler.RecordEvent("record_mul")
 record_event.begin()
 data1 = paddle.randn(shape=[3])
 data2 = paddle.randn(shape=[3])
 result = data1 * data2
 record_event.end()
