Must specify at least one GPU id

I’m trying to use the ‘TLT CV Inference Pipeline Quick Start Scripts’. tlt_cv_start_server.sh seems to be unable to find the GPU.
Can you tell me what is causing this?

environment: Jetson Nano & JetPack 4.5.1

~/workspace/quickstart/scripts$ bash tlt_cv_start_server.sh
