Thanks for all the advice, I now succeeded in make the test example work.
The problem were the drivers and not pyopencl/conda in the end. I ahd CentOS7.7
installed however the drivers were for CentOS7.6 only.
I am currently testing CENTOS 8.0 with the corresponding drivers for Radeon
VII. The test code works so far. lets see if any other issues ;)

You could check if your user account belongs to the video group, a common
pitfall with AMD drivers.
"To add yourself to the video group you will need sudo privileges; you can
issue the following command:
sudo usermod -a -G video $LOGNAME
You will need to log out and in again to activate this change.“
