Hi.
Has there been any change in the Frigate and coral TPU settings?
frigate.yml:

detectors:
coral1:
type: edgetpu
device: pci:0
coral2:
type: edgetpu
device: pci:1

Because it gives me the error and does not launch Frigate:

2024-12-25 10:19:25.022360396  [2024-12-25 11:19:25] frigate.detectors.plugins.edgetpu_tfl ERROR   : No EdgeTPU was detected. If you do not have a Coral device yet, you must configure CPU detectors.

Which coral do you have? What hardware is this running on?

forest tundra Hi. Has there been any change in the Frigate and coral TPU settings? frigate.yml...

Just want to make sure, you have correct syntax with yaml formatting and you're correctly passing your pcie cards via docker (if that's how you installed it). Please check.

Hi. Thanks for the reply.

I have been using M.2 Accelerator with Dual Edge TPU on an 8 core PC with 32 GB RAM! for over 1 year and everything worked until the HA upgrade.

In Proxmo I see:

08:00.0 System peripheral: Global Unichip Corp. Coral Edge TPU
09:00.0 System peripheral: Global Unichip Corp. Coral Edge TPU

#

If I understand correctly, there was an upgrade of the Python library in HA and now it doesn't work somehow.

If I remove coral and add CPU, my frigate starts:

detectors:
cpu1:
type: cpu
cpu2:
type: cpu
# coral1:
# type: edgetpu
# device: pci:0
# coral2:
# type: edgetpu
# device: pci:1
