[Support]: PCI-e Coral TPU not recognized in Frigate. bare metal, HA supervised docker qemux86-64 install

Describe the problem you are having

Hello,

I have an M.2 dual TPU card in a pci-e adapter that worked when I test ran the coral demo bird library in command line before installing Frigate on a bare metal workstation, HA supervised docker qemux86-64 install. However, the TPU is not detected in the Frigate logs (at bottom). Now after the Frigate install the coral bird demo no longer works. What is causing this issue and how might I correct it? Thank you blakeblackshear for all of your knowledgeable help, and work on this project.

John

I think it was a flakey PCIE adapter card. I bought a m.2 ekey to mpcie adapter, chmod 777 /dev/apex_0, and tried it in a notebook pc and the coral is detected in frigate now.

Thanks for the help, John

@jb2590 isnt supervised in a container - as such how are you expecting PCI devices to be passed through into the container? you will need to make sure the container gives you full host privileges, by default IIRC home assistant docker implementation doesn’t do that… hopefully the 777 fix suggested above is enough, else make sure the container if full privileged.
