This is seems to me a deployment issue. Somehow in your environment the
python installation is broken and some of the packages are import from
python 3.7 into the python 3.6 interperter. This is not a nova issue so
I'm setting it to Invalid. If you used any kind of deployment engine
then please report a bug there. If you manually deployed openstack than
review your python installation procedures.

** Changed in: nova
       Status: New => Invalid
