coral tpu, usb, proxmox, lxc container, unprivileged, docker, frigate, home assistant, debian, python
This guide is how I got a Coral TPU (USB) working in an unprivileged LXC container.
At the end, you should be able to use the Coral TPU for inferencing inside of an unprivileged LXC container as well as Docker containers within the LXC, such as Frigate.
This does NOT require privileged LXC or docker container.
