安装nvidia驱动报错：ERROR: An NVIDIA kernel module ‘nvidia-uvm’ appears to already be loaded in your kernel

1.报错信息

ERROR: 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 us
ing the GPU(s) before attempting to upgrade your driver.  If no GPU-based programs are running, you know that your k
ernel supports module unloading, and you still receive this message, then an error may have occurred that has corrup
ted an NVIDIA kernel module's usage count, for which the simplest remedy is to reboot your computer.

2.查看内核模块

# lsmod | grep nvidia
nvidia_uvm            995356  2 
nvidia_drm             53134  0 
nvidia_modeset       1195268  1 nvidia_drm
nvidia              35237551  14 nvidia_modeset,nvidia_uvm
drm_kms_helper        179394  2 i915,nvidia_drm
drm                   429744  5 i915,drm_kms_helper,nvidia,nvidia_drm

3.卸载相应模块，报错

# rmmod nvidia_uvm
rmmod: ERROR: Module nvidia_uvm is in use

4.查看并结束相应进程

# lsof /dev/nvidia*
