The bbox outputs of the Yolov3-Tiny model are absurd

Which Khadas SBC do you use?


Which system do you use? Android, Ubuntu, OOWOW or others?

Ubuntu 20.04


I converted my yolov3-tiny model with KSNN on own PC as follows.

I transferred the .nb and .so files to khadas.

my model has two classes. I changed LISTSIZE = 7, NUM_CLS=2 , CLASSES= (“class1”,“class2”) in file ksnn/example/darknet/


When I run this file, the output is as follows. Bboxes are absurd.

pre and post processes as in your yolov3 demo file.

@Frank can you help me with my question?

This demo of mine is only suitable for the output type of uint8.

If you are int8, you can refer to the following post-processing source code
