环境：ubuntu16.04
在kolla-ansible单节点部署openstack并执行到下面这步时报了错误,可能是我系统环境中既有python2又有python3
初始化基本的运行环境（镜像和网络等）
. /usr/local/share/kolla-ansible/init-runonce
其实我这边的情况是有两个地方要改，分别编辑这两个文件，将 import queue 替换为 from multiprocessing import Queue as queue ，然后按esc，输入wq命令保存退出即可。
In my case:
-
usr/local/lib/python2.7/dist-packages/openstack/utils.py- line 13 -
/usr/local/lib/python2.7/dist-packages/openstack/cloud/openstackcloud.py- line 14
# replace "import queue" with: from multiprocessing import Queue as queue
再次运行. /usr/local/share/kolla-ansible/init-runonce，可以看到不报错了，问题解决！
