创建 TPU 时出错："cannot be less than the existing policy version"

Question

我正在尝试使用 GC 控制台创建 TPU：

ctpu up --name=daniels-tpu --zone=us-central1-b --tpu-size=v3-8 --tf-version=1.15 --tpu-only -noconf --require-permissions

并且我收到以下错误：

ctpu will use the following configuration:
Name:                 daniels-tpu2
Zone:                 us-central1-b
GCP Project:          ai2-aristo
TensorFlow Version:   1.15
Cloud TPU:
Size:             v3-8
Preemptible:      false
Reserved:         false
OK to create your Cloud TPU resources with the above configuration? [Yn]: y

有什么想法吗？

我能够使用相同的命令成功创建 TPU 实例。您是否尝试过使用其他区域？ 我还发现了一个我认为可能非常有用的线程。
