pod状态UnexpectedAdmissionError

[ledrsnet]

pod的yaml如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    k8s-app: vcuda-test
    qcloud-app: vcuda-test
  name: vcuda-test
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: vcuda-test
  template:
    metadata:
      labels:
        k8s-app: vcuda-test
        qcloud-app: vcuda-test
    spec:
      containers:
      - command:
        - sleep
        - 360000s
        env:
        - name: PATH
          value: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
        image: ccr.ccs.tencentyun.com/menghe/tensorflow-gputest:0.2
        imagePullPolicy: IfNotPresent
        name: tensorflow-test
        resources:
          limits:
            cpu: "1"
            memory: 8Gi
            tencent.com/vcuda-core: "50"
          #  tencent.com/vcuda-memory: "32"
          requests:
            cpu: "1"
            memory: 8Gi
            tencent.com/vcuda-core: "50"
           # tencent.com/vcuda-memory: "32"

当我注释掉vcuda-memory 这一行时，我apply应用pod，pod状态为UnexpectedAdmissionError，describe pod得到如下信息：
