Openvino on Xeon(R)E5-2643 illegal instruction

Jump to solution

Hello, my os is centos7 with intel Xeon E5-2643.

After build openvino, I run the test demo by "./demo_squeezenet_download_convert_run.sh", but got "illegal instruction" error.

Solved. The reason may be the version of cpu is not supportted by Openvino. I turned to another cpu server,  Intel(R) Xeon(R) Gold 6278C, and everything worked fine.

Hi Lumo Wang,


Thanks for reaching out.

Yes, Intel® Xeon® Gold 6278C is not supported by OpenVINO. You can find the information on hardware supported by OpenVINO on this page.
