运行样例的连接：

我是直接按照Readme里的命令行步骤运行的，运行到：

cd $HOME/samples/cplusplus/level2_simple_inference/2_object_detection/YOLOV3_coco_detection_picture/scripts    
bash sample_build.sh

命令时报错：

sample_build.sh: line 5: /usr/local/Ascend/thirdpart/aarch64/common/sample_common.sh: No such file or directory

[INFO] Sample preparation

sample_build.sh: line 11: target_kernel: command not found

觉得是配置环境变量的问题，但是又不知道该配置什么环境变量。

有大佬能指点以下吗
