BackendAllocatorException in dfc haf2hef conversion

I install 3.28 dfc in virtual system "Ubuntu 20.04.6 LTS (GNU/Linux 5.15.0-107-generic x86_64)" in VMware software, the onnx to haf/quantized har is ok, but quantized har to hef file failed.

In other words, I guess it needs hailo hardware to compile. I have put hailo8 hardware in the arm development board, so how can i convert quantized har file to hef file under this situation?

I hope get your answers. It's been bothering me for a long time.
