msPTI快速入门

建议按照“安装工具 > 配置环境 > 运行样例”的顺序完成快速体验：

1. 完成工具安装。 请先参见 《msPTI 工具安装指南》完成msPTI工具安装。

2. 配置CANN环境变量。

   source ${install_path}/set_env.sh
   

   其中${install_path}需要替换为CANN的安装路径，例如/usr/local/Ascend/cann。

3. 进入样例目录并执行脚本。

   cd ${install_path}/tools/mspti/samples/mspti_activity
   bash sample_run.sh
   

   看到如下信息，则表示运行成功：
