Hello,
I'm doing my machelor thesis, and I found a very interesting phenomenon. I deployed a Yolov8n from model zoo inside the N6 Nucleo Board NPU(by modifying the template project from the DK board and Input from the UART with CRC code to make sure the picture is send correctly.) the inference seems to be right. However, when I input the same data (same picture with same crc code), the output can be different!!???? Is this phenomenon right? or its because I messed up sth. when I change the project???????
Also even if I deploy this Yolov8n inside CPU without NPU, the outcome is still different when giving the same input. (the reference seems also working correctly.) Is this also correct??? any explanation or documentation for this?
(the mAP can have a 20% different when giving 10 same pictures)
Also when using a mobilenet v2 the same phenomenon is also found both in CPU and NPU,( top 5 class is same ,but the confidence can have a difference up to about 20 %)
please give me some ideas whether this is right or wrong, when its wrong, what should I do to fix this? when right, can you give me some documentations about this?
Thanks a lot in advance.
