Hi,

Good day to you.

Thank you for posting in Intel communities.

According to the basetoolkit system requirements, we can see RHEL 7.9 is deprecated. So, most of the oneapi tools don't work on the deprecated platform. We suggest you try it on the supported OS.

Link:

Intel® oneAPI Base Toolkit System Requirements

We ran numba_dpex on RHEL 7.9(deprecated) and got the same issue. Attaching a screenshot for your reference.

We ran numba_dpex on Ubuntu18.04 and it is working fine. Attaching a screenshot for your reference.

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue. Thank you!

Regards,

Jaideep
