我正在尝试创建一个python程序，该程序将创建所提供数量的相同虚拟机。我已经使用了社区示例脚本来尽可能多地运行，但我现在完全陷入了困境。

AttributeError: 'NoneType' object has no attribute 'CreateVM_Task'
我知道我的CreateVM_task返回了一个none参数，但我似乎不明白为什么。
配置参数出现问题。使用当前代码，数据中心和vmfolder对象在打印时返回为无对象。为了解决这个问题，我将其编辑到下面的块中。
content = service_instance.RetrieveContent()
datacenter = content.rootFolder.childEntity[0]
vmfolder = datacenter.vmFolder
hosts = datacenter.hostFolder.childEntity
resource_pool = hosts[0].resourcePool
