一、问题现象（附报错日志上下文）： 

当前YOLOV7MultiInput demo 我已经按照步骤完成到 bash sample_run.sh 执行时报错 [error] Retry 

二、软件版本: 

-- CANN 版本 (CANN 7.0.RC1):   

-- 固件与驱动版本 (23.0.RC3) 

-- 操作系统版本 (Ubuntu 22.04 LTS aarch64): 

-- 硬件设备 (Atlas 200I DK A2 开发者套件)

 

三、测试步骤： 

cd /home/HwHiAiUser/samples/inference/modelInference/sampleYOLOV7MultiInput/scripts 

bash sample_build.sh 

bash sample_run.sh
