我正在尝试编写一个 python 程序来帮助我管理我的虚拟机。当我在某个时候创建​​多个虚拟机时，会发生错误：

    async_vm_creation = compute_client.virtual_machines.create_or_update(
  File "C:\Python38\lib\site-packages\azure\mgmt\compute\v2019_03_01\operations\virtual_machines_operations.py", line 292, in create_or_update
    raw_result = self._create_or_update_initial(
  File "C:\Python38\lib\site-packages\azure\mgmt\compute\v2019_03_01\operations\virtual_machines_operations.py", line 252, in _create_or_update_initial   
    raise exp
msrestazure.azure_exceptions.CloudError: <unprintable CloudError object>

我一直在寻找类似的问题，但找不到适合我的解决方案！有没有人知道问题是什么？

这是我创建虚拟机的函数：当我想创建 VM 时，使用相应的凭据调用“createVM”方法
