What does this mean? What have you set as “608” or “1536”?

[wilicyy]

hi,
it is for custom yolo model, trained by 608X608, or 1536X1536, or 412X412, like that.

thanks!

It may be caused by SGIE. When the model dimension is 1536x1536 and the PGIE detects objects whose size is less than 256x256, the HW scaler can not scaling the object to the model size for the HW limitation(Jetson HW can only scale 1/16 to 16 ratio). Please avoid such configuration.

ok get it.
thank you very much!
