根据你提供的错误信息，这是由于 Deployment 中的 spec.template.spec.affinity.nodeAffinity.requiredDuringSchedulingIgnoredDuringEXecution 字段在 Kubernetes 版本中没有被识别导致的。这个字段在 Kubernetes 1.18 版本之后的版本才被引入。

你可以将该字段修改为 `requiredDuringSchedulingIgnoredDuringExecution` （注意拼写），然后再次尝试应用该部署文件。修改后的部署文件如下所示：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 5
  template:
    metadata:
      labels:
        app: nginx
    spec:
      affinity:
        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
              - matchExpressions:
                - key: gpu
                  operator: In
                  values:
                  - "true"
      containers:
      - name: nginx
        image: registry.cn-hangzhou.aliyuncs.com/wsl_images/nginx:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

然后使用 `kubectl apply -f nginx.yaml` 命令再次尝试部署该文件。
