oneAPI 2021.4 installed from apt packages, but also oneAPI 2021.3 packages installed in conda build environment. I think there is conflict. I will try to remove oneAPI from system and use only conda packages.

oneAPI 2021.4 installed from apt packages, but also oneAPI 2021.3 packages installed in conda build environment. I think there is conflict. I will try to remove oneAPI from system and use only conda packages.

The root cause is in new version of oneDPL/PSTL (one of components in oneAPI), it has incompatible changes.
This component is not present yet as a Python package, that is why using only packages is impossible.

Downgrading of oneDPL/PSTL to previous version (made by downgrading of oneAPI) is a temporary way of dealing with a problem, it should be fixed in future. Created issue #986
