GCC on CentOS 7 is quite old and does not have std::regex implementation (https://stackoverflow.com/questions/35793340/function-regex-of-c-meet-error-in-linuxcentos-but-in-osx). Recently open_model_zoo has added memory and cpu monitoring features which use std::regex (https://github.com/opencv/open_model_zoo/blob/efd238d02035f8a5417b7b1e25cd4c997d44351f/demos/common/monitors/memory_monitor.cpp, https://github.com/opencv/open_model_zoo/blob/efd238d02035f8a5417b7b1e25cd4c997d44351f/demos/common/monitors/cpu_monitor.cpp).

As I can see memory and cpu monitoring can be enabled by the "-u" option (empty by default), but it seems it still tries to parse something. I'd recommend you to file an issue report here: https://github.com/opencv/open_model_zoo/issues

Hi xuanzhuang,

Are you able to successfully run the demo_security_barrier_camera.sh Verification Script ?

Also, are you trying to remotely access this machine?

Regards,

Jaivin
