Frigate Coral TPU Detector Inference Speed very slow

[jumahrauf]

Hello,

I have a Proxmox system running on Dell Wyse 5070.
The Google Coral is installed as a M.2 Accelerator A+E unit.
I installed firgate with the Proxmox helper Script Frigate LXC.
The driver is installed on the host system, TPU is recognized and the Coral TPU is passed through to frigate.
Frigate recognizes the Coral TPU

Log: frigate.detectors.plugins.edgetpu_tfl TPU found

However I get the warning that Coral TPU is very slow.
Detector Inference Speed: almost constant at 394.24ms
Detector Temperature: 56°C
Detector CPU Usage: constant at 98,8 %
Detector Memory Usage: 0,9 %

Right now I configured 1 camera.

Okay,
probably I found the answer.
I had to change the
model:
path: /edgetpu_model.tflite

Now the values of coral went dramatically down.
Detector Inference Speed: around 9.22ms
