I am trying to setup one small kubenertes cluster on my ubuntu 18.04 LTS server. Now every step is done, but checking the GPU status fails. The container keeps reporting errors:

1. Issue Description
I have done steps by Quick-Start, but when I run the test case, it reports error.

2. Steps to reproduce the issue

• exec shell cmd

  docker run --security-opt=no-new-privileges --cap-drop=ALL --network=none -it -v /var/lib/kubelet/device-plugins:/var/lib/kubelet/device-plugins nvidia/k8s-device-plugin:1.9

• check the erros

  2020/02/09 00:20:15 Starting to serve on /var/lib/kubelet/device-plugins/nvidia.sock
  2020/02/09 00:20:15 Could not register device plugin: rpc error: code = Unimplemented desc = unknown service deviceplugin.Registration
  2020/02/09 00:20:15 Could not contact Kubelet, retrying. Did you enable the device plugin feature gate?
