Errors occurred after Are your cluster is in Azure cloud or not？

Hello, I am a developer from China, tying to deploy pai v1.8.0 in a private cloud,

enviroment: Ubuntu16.04 + OpenPAI v1.8.0

As you can see, i tried to use https://openpai.readthedocs.io/zh_CN/zh_cn_pai-1.5.y/manual/cluster-admin/configuration-for-china.html , but it not works, so I replaced some links to make sure I could access the mirrors I needed.

like this:
`

dashboard_image_repo: "registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-{{ image_arch }}"
`

Then, I used the quick-start-kubespry.sh to deploy pai, the error occured:
... Generating kubespray configuration Are your cluster is in Azure cloud or not? (Y/N) (case sensitive)N Traceback (most recent call last): File "/root/pai/contrib/kubespray/script/k8s_generator.py", line 72, in <module> main() File "/root/pai/contrib/kubespray/script/k8s_generator.py", line 67, in main map_table File "/root/pai/contrib/kubespray/script/utils.py", line 53, in generate_template_file generated_template = generate_from_template_dict(template, map_table) File "/root/pai/contrib/kubespray/script/utils.py", line 41, in generate_from_template_dict map_table File "/usr/local/lib/python3.5/dist-packages/jinja2/environment.py", line 1008, in render return self.environment.handle_exception(exc_info, True) File "/usr/local/lib/python3.5/dist-packages/jinja2/environment.py", line 780, in handle_exception reraise(exc_type, exc_value, tb) File "/usr/local/lib/python3.5/dist-packages/jinja2/_compat.py", line 37, in reraise raise value.with_traceback(tb) File "<template>", line 410, in top-level template code TypeError: 'NoneType' object is not iterable

Is there a way to fix this or make sure that I can deploy it correctly?

By the way, i also tried the method mentioned in the #5592 , it performs more processes but ultimately still faild.

Thank you.

Start with contrib/kubespray/script/k8s_generator.py and utils.py, then inspect the template referenced by the traceback around line 410 and the quick-start-kubespry.sh flow. Reproduce the OpenPAI v1.8.0 deployment with the provided configuration and determine what causes the NoneType iteration; done means the configuration generates and deployment proceeds without this error.
