Failed to create deployment

[Jicming]

When I use the examples in the document to execute, I report an error
The code is as follows：

from kubernetes import client, config
config.load_kube_config(config_file='config/config_14b')
apps_api = client.AppsV1Api()
deployment = client.V1Deployment()
deployment.api_version = "apps/v1"
deployment.kind = "Deployment"
deployment.metadata = client.V1ObjectMeta(name="nginx-deployment")

spec = client.V1DeploymentSpec()
spec.replicas = 3

spec.template = client.V1PodTemplateSpec()
spec.template.metadata = client.V1ObjectMeta(labels={"app": "nginx"})

spec.template.spec = client.V1PodSpec()
container = client.V1Container()
container.name="nginx"
container.image="nginx:1.7.9"
container. ports = [client.V1ContainerPort(container_port=80)]
spec.template.spec.containers = [container]
deployment.spec = spec
apps_api.create_namespaced_deployment(namespace="default", body=deployment)
deployment.spec.template.spec.containers[0].image = "nginx:1.9.1"
apps_api.replace_namespaced_deployment(name="nginx-deployment", namespace="default", body=deployment)
apps_api.delete_namespaced_deployment(name="nginx-deployment", namespace="default", body=client.V1DeleteOptions(propagation_policy="Foreground", grace_period_seconds=5))

The error is as follows：

Issue #1662 can resolve this problem by disabling the client side validation
Why not follow this example
