ImportError: C extension: numpy.core.multiarray failed to import not built.
When I am installing devstack-single node openstack package, It needs pandas, while installing facing error as below

>  ImportError: C extension: numpy.core.multiarray failed to import not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace --force' to build the C extensions first.


If do manual installation of pandas by using "python setup.py build_ext --inplace --force" from source its running fine, but cannot instruct other dependencies software to clone and do it forcefully. 

it will be good if installed normally than force inplace
