Comment 1 for bug 1724538

The message means the numpy used during pandas compilation is different from the numpy at runtime. This fail is about packaging problem. On Openstack-ansible all the pip packages are mirrored and fetched on the repo_server. so I realized that pandas version 0.21.0rc1 is installed but this version is not stable. it is not compatible with numpy 1.12.0 version. I asked gnocchi channel and they suggested using pandas stable version. So I tried it and it worked.
