Python 如何使用pyvmomi创建虚拟机

我正在尝试创建一个python程序，该程序将创建提供数量相同的虚拟机。我已经使用社区示例脚本尽可能多地运行，但现在我完全被卡住了

我知道我的CreateVM_任务返回的参数为none，但我似乎不明白为什么

问题在于配置参数。使用当前代码，数据中心和vmfolder对象在打印时返回为无。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

无论您在这条语句中想说什么，都是错误的，在Python-3.x中是不可能的。您确定使用3.x吗？我在Python3.7环境中工作，我正在使用的sdk示例代码也在3.x中。那条线是我用它制作的样本的一部分。我把它拿走了，因为我认为它不需要。删除该行后，错误仍然存在。
