Describe the problem you are having

I have sifted through the frigate documentation, and I've made several tweaks to my config to get it going. I could have possibly missed something but I am getting the CPU detectors are not recommended error and high cpu usage. I think I have everything set correctly to use my Nvidia 4060 (plex uses the same) with Frigate.

I've brought in detection on sub streams and recording on the main stream.
My streams are 265 codec but my system and all devices can view this no problem (as far as I can see)
I've set up zones and motion masks on the timestamps and garden shrubs.
disabled audio detection
change shm size to --shm-size=1g
add this to parameters in unraid --runtime=nvidia

Hardware is:
Unraid OS v7
AMD Ryzen 9 5900X / 64gb DDR4 Ram
Running Frigate in docker from the app store.

I am trying to get the TensorRT engine working instead of my setup, but with the error I don't think TensorRT is running correctly and it instead is using my AMD Ryzen CPU?

Version

Thanks for the reply. I was able to get it going.

I have added the below in my config.yaml and added 'yolov7-320' to the YOLO_MODELS parameter when launching the container in unraid.

detectors:
  tensorrt:
    type: tensorrt
    device: 0 #This is the default, select the first GPU
model:
  path: /config/model_cache/tensorrt/yolov7-320.trt
  input_tensor: nchw
  input_pixel_format: rgb
  width: 320
  height: 320

We will need to see your config with tensorrt configured.

Are you referring to the docker command or the config.yaml?

EDIT: I am using the container image that has the tensorRT built in. Iam providing the grpahics card ID to the container so it should detect it automatically?

No, you have to define the detector, like it says in the docs https://docs.frigate.video/configuration/object_detectors#configuration-parameters
