[Detector Support]: No EdgeTPU was detected Google coral #15021
-
Describe the problem you are havingI see a lot of issues and have tried for a few days to resolve following other peoples issues. This is my setup: I couldn't for the life of me get the Coral to initialize but after alot of work I managed to consistantly get it to initialize using this magical DockerFile: https://github.com/tnyeanderson/zet/tree/main/20240114030411 I have passthrough for the whole USB port in proxmox, meaning I have to attach the USB to the docker image to initialize coral, the detach, and reattach to home assistant VM lsusb inside home assistant now displays initialized device: Unfortunately Frigate always comes back with Version0.14.1-f4f3cfa Frigate config filemqtt:

There are many layers of virtualzation happening here - you may have better luck using the tteck script and installing Frigate in a Proxmox LXC. Users have reported success that way, and there's lots of support available on the tteck github. |

Thanks - I tried the tteck LXC script but ran in to some issues since the script also installed OpenVino which failed every time, probably because my CPU doesn't support AVX2 instruction set (8 x Intel(R) Xeon(R) CPU E5620) I did however fork and comment out the OpenVino part from the script which led me to a successful install - Although I'm still struggling with getting Frigate to use Google Coral. My host identifies the coral as expected now: So does the LXC container: Frigate.yml: Frigate logs: |

Your
deviceline in your frigate config is incorrect. It needs to just bedevice: usb. See the documentation:https://docs.frigate.video/configuration/object_detectors/#single-usb-coral
