Our server still runs Nvidia Driver Version 384.130, thus I can max go up to CUDA 9. I downgraded Pytorch 1.1.0 to Pytorch 1.0 with CUDA 9. Thank you.
On a different note, What is the safest way to update Nvidia driver on a Ubuntu 16.04 server with around 20 active users at any instance without disturbing any running processes? Because whenever I have try to update Nvidia driver on my Ubuntu 16.04 workstation, something or the other breaks.
