amdgpu driver or pytorch driver will not add your current into the render and video groups directly.

Due to the rocminfo need access the /dev/kfd and /dev/dri which owned by render group.

you should add current groups into this two groups in linux command line, suck like
sudo usermod -aG render,video <your_current_user_name>
using groups <user_name> or id <user_name> or cat /etc/group to doule confirm.

Then reboot your linux machine make sure the changes works.
Run this script again.

(Optional)if necessary add sudo or root priviledge.
sudo usermod -aG render,video,sudo,root <your_current_user_name>
Removing user <usr_name> from group root
sudo gpasswd -d <usr_name> root or sudo deluser <usr_name> root
