I’ve been trying to downgrade from CUDA 10.1 to CUDA 9.2 on a RHEL 7.6 box.
I started out trying to load them both… that caused quite a bit of grief.
I finally got back to where I started with CUDA 10.1 running, then I uninstalled that and try to install cuda 9.2 and I’m now getting a circular reference in yum.
It removes xorg-x11-drv-nvidia-gl (and a few other X packages) due to obsoletes from the installed nvidia-driver-418.
It then throws an error on loading cuda-drivers-396 because it has a dependency on xorg-x11-drv-nvidia-gl, which it just removed because it was obsoleted it with 418.
How do I get CUDA 9.2 installed?
(background as to why: I’m trying to get the UCX that is packaged with HPC-X to run, but it appears to have a dependency on 9.2)
