An NVIDIA kernel module ‘nvidia-uvm’ appears to already be loaded in
your kernel. This may be because it is in use (for example, by an X
server, a CUDA program, or the NVIDIA Persistence Daemon), but this
may also happen if your kernel was configured without support for
module unloading. Please be sure to exit any programs that may be
using the GPU(s) before attempting to upgrade your driver. If no
GPU-based programs are running, you know that your kernel supports
module unloading, and you still receive this message, then an error
may have occurred that has corrupted an NVIDIA kernel module’s usage
count, for which the simplest remedy is to reboot your computer.
