I have install hailort and tappas sucessfully, I want to test how many cameras hailo8l can support so I run this：
https://github.com/hailo-ai/Hailo-Application-Code-Examples/tree/main/runtime/gstreamer/multistream
But I get error like below:
(hailo_env) ain@pi5-hailo:~/tappas/scripts/gstreamer $ ./install_hailo_gstreamer.sh
