Did you try to install os-collect-config using pip? If you did that, pip might have tried to update several Python libraries used by OpenStack components, and that usually creates a mess in your system.

It is possible to recover from it by manually uninstalling and reinstalling the modules updated by pip, but it can be complicated. If it is a test system I would suggest reinstalling.

Javier
