I’m trying to scheduling GPU in Kubernetes v1.13.1 and I followed the guide in https://kubernetes.io/docs/tasks/manage-gpus/scheduling-gpus/#deploying-nvidia-gpu-device-plugin

But the gpu resources doesn't show up when I run kubectl get nodes -o yaml, according to this post, I checked the Nvidia gpu device plugin.

I run:

kubectl create -f https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/v1.11/nvidia-device-plugin.yml

several times and the result is

Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/v1.11/nvidia-device-plugin.yml": daemonsets.extensions "nvidia-device-plugin-daemonset" already exists

It seems that I have installed the NVIDIA Device Plugin? But the result of kubectl get pods --all-namespaces is

When I run kubectl describe node, gpu is not in the the allocatable resource
