Running ObjectDetectionLoop.ino

it is getting video feed ok but
on Serial Monitor it is printing

Total number of objects detected = 0

error: vipnn not applied

Hi @chompangyi, which SDK version are you using? You can check it at boards manager on Arduino IDE. Are you running the default examples in the SDK without modifying anything?

I have tested on Win10, Arduino IDE 2.3.2 and SDK version v4.0.6 and its working fine.

I think that it is due to no dnn file
I try to upload via conversion tool but it fails many time
is there any available YOLOV4 Tiny or YOLOV7 Tiny generated

You can find all the available default models in C:\Users{username} \AppData\Local\Arduino15\packages\realtek\hardware\AmebaPro2{SDK version}\variants\common_nn_models

For using customized model, you can refer to

@chompangyi
which SDK version are you using?
which Arduino IDE?
which example? do you have the link of the demo or source code?

Thank you for the reply. We had tried your env to build and this is no errors. So I would like to suggest you,

I installed Arduino and AMB82-MINI straight-forward on a new notebook. Everything worked fine - also RTSP video streaming was perfect. IDE is v2.3.2, ameba is v4.0.6.

The facedet-model is: (FACE_DETECTION, DEFAULT_YOLOV3TINY, DEFAULT_SCRFD, NA_MODEL);

Now I got the same error when trying to experience the given NN face detection sample: error: vipnn not applied

This error is repeated output on serial - the video can be received, but without any OSD.

Trying to increase the NN_SIZE in the linker_scripts → amebapro2_ram_arduino.ld did not work either.

Has anyone an idea for this failure?
Thank you so much for your suggestions!

Hi @HDP,

It should be NA_MODEL instead of DEFAULT_YOLOV3TINY.

Thank you.
