我在使用python 2.7的ubunty 64并使用PyYAML-3.10

下面是我的yaml文件:

host:localhost
username:root
password:test
database:test
operations_database:operations
treeroot:
    branch1:
        name: Node 1
        branch1-1:
            name: Node 1-1
    branch2:
        name: Node 2
        branch2-1:
            name: Node 2-1

当我运行以下代码时,我得到以下错误.但是,如果我删除treeroot上方的行,则代码可以正常工作:

from yaml import load, dump
try:
    from yaml import CLoader as Loader, CDumper as Dumper
except ImportError:
    from yaml import Loader, Dumper
f=open('amazon.yaml')  
data = load(f, Loader=Loader) 

Traceback (most recent call last):
