How to use another model on frigate?

[JuanpaFasta]

Hi, I am currently working on a parking lot detector, but I want to use Frigate so I can add automations with HAOS. The problem I'm having is that the default model used in Frigate when specifying "edgetpu" for detectors (I want to use my Coral TPU) doesn't detect cars from above. The solution I proposed was to use another model, but every time I try, my Frigate doesn’t start or crashes. I’m not sure what I’m doing wrong. Has anyone successfully used a different model before?
PD: I already followed the steps of the documentation and Frigate crashes.

Specs:

• Frigate (full access)
• HAOS on a Raspberry Pi 4
• Coral TPU

My yml:

detectors:
  coral:
    type: edgetpu
    device: usb
    #model:
      path: \config\customiamodels\efficientdet_lite2_448_ptq_edgetpu.tflite
      width: 448
      height: 448
      input_tensor: "nhwc"
      input_pixel_format: "rgb"

we'll need to see the logs to be able to help

Okay, here are my logs from today:

your config is not formatted correctly. The model config should be its own config group

Thank you so much! It was a simple error, but now it works perfectly.

For anyone struggling with the efficientdet_lite2 model, here is what worked for me in the .yml file:

detectors:
  coral:
    type: edgetpu
    device: usb

model:
  path: /config/customiamodels/efficientdet_lite2_448_ptq_edgetpu.tflite
  width: 448
  height: 448
  input_tensor: nhwc
  input_pixel_format: rgb
