 ## Preparing the Training Script
 
-To enable the performance profiling of neural networks, MindSpore Profiler APIs should be added into the script. At first, the MindSpore `Profiler` object need to be set after set context and before the network initialization. Then, at the end of the training, `Profiler.analyse()` should be called to finish profiling and generate the perforamnce analyse results.

 ## 准备训练脚本
 
 为了收集神经网络的性能数据，需要在训练脚本中添加MindSpore Profiler相关接口。  
-- 在`set_context`之后和初始化网络之前，需要初始化MindSpore `Profiler`对象。

 - 在训练结束后，调用`Profiler.analyse()`停止性能数据收集并生成性能分析结果。
