Please describe your issue below:

Working on KSNN usage (KSNN Usage | Khadas Documentation) and KSNN conversion tool (Instructions for KSNN conversion tool | Khadas Documentation) tutorials and implementing my own model I want to. When I run the “./convert” command, I get errors “bash: ./convert: cannot execute binary file: Exec format error” and “bash: ./convert: No such file or directory”. Images of the errors are below. In my research, I could not find a solution to this problem. Could you help?


@Huseyin_Cayirli Hello, please use SDK to convert . This just a test demo.

@Frank Hello again,

I already tried the SDK to convert tutorial you mentioned. I tried again with your suggestion and got the same error again. You can see the error in the image below. I cannot run the “convert” file. What could be the reason for this?

@Huseyin_Cayirli SDK work with your PC. not in the VIM3.

@Frank Then, in order to run my own model real time on NPU, I need to preprocess (running “./convert” to create the .so file etc.) on the pc and then use VIM3 to run only real time?

@Huseyin_Cayirli Yes. You convert it on PC, then move it to your VIM3 and run.

@Frank As you said, I was able to run the convert command on the pc and convert the inception model in the demo. Thank you for the information.

Now, I tried to convert my own models, yolov5s and yolox-tiny, separately in onnx and pytorch formats. However, I encountered the following errors. What could be the cause of these errors?

Pytorch-YOLOv5s ERROR

ONNX-YOLOX-tiny ERROR
