When installing cuda, it asked if I wanted to install accelerated drivers. I said yes. I think that might have broken my build as it worked when I installed the stuff manually.
However…
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing with the name of this run file:
sudo .run -silent -driver
It was NVIDIA-Linux-x86_64-375.26 that fixed my machine. Why is it broken?
