I am getting "ValueError: Failed to load delegate from libedgetpu.so.1.0" repeatedly on frigate on docker inside LXC container on Proxmox host. I also Tried on a VM (with PCI bypass, and got the same error).

AFAIK TPU is detected on the system (both proxmox and LXC) I get the following output on LXC

Code: 
root@pve:# ls /dev/apex_0
/dev/apex_0
root@pve:# lspci -nn | grep 089a
01:00.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]


LXC config

I am using Mini PCIe Accelerator (G650-04528-01 ) any help will be greatly appreciated. Above error is from frigate on docker but I get the same error when I try to run the sample project.

I am also getting following with dmesg | grep -i apex


Code: 
root@FrigateLXC:~# dmesg | grep -i apex
[   18.429956] apex 0000:04:00.0: enabling device (0100 -> 0102)
[   23.586928] apex 0000:04:00.0: Apex performance not throttled due to temperature
root@FrigateLXC:~# dmesg | grep -i apex^C
 
I think I figured it out. Permissions issue. Adding the following in /etc/pve/lxc/102.conf got me over the hump:
lxc.cgroup2.devices.allow: c 226:0 rwm​
lxc.cgroup2.devices.allow: c 226:128 rwm​
lxc.cgroup2.devices.allow: c 29:0 rwm​
lxc.cgroup2.devices.allow: c 189:* rwm​
lxc.cgroup2.devices.allow: c 120:* rwm​
lxc.cgroup2.devices.allow: a​

I referenced frigate discussion 1111.
Can now run the test steps from the coralai install instructions and infer the macaw in the lxc.
