I recently upgraded from CUDA 7.5 to CUDA 8.0 on my Ubuntu 14.04 LTS machine for one project.
Later I returned to working on an older project that makes use of the StereoLabs ZED driver (V1.1.0) but it turns out that this driver requires CUDA 7.5 and won’t work with CUDA 8.0
Unfortunately I removed CUDA 7.5 after the upgrade to 8.0.
The latest ZED driver that is compatible with CUDA 8.0 is only available for Ubuntu 16, and it doesn’t work on Ubuntu 14.04 LTS (I tried).
It seems I am looking at two options: either go to Ubuntu 16, or somehow get CUDA 7.5 back on my machine.
I’d like to hold off upgrading my OS for now.
Is it possible to install CUDA 7.5 again, next to the existing installation of CUDA 8.0 and if so, how should I go about it?
Thanks in advance
