Hi, I don't know if it's a known issue, but we have this patch in Ironic here https://review.openstack.org/#/c/124610/ and the gate jobs for python26 and python27 are failing because of some import error[1] and it doesn't show me what is the error exactly, it's important to say also that the tests run locally without any problem so I can't reproduce the error locally here. Have anyone seem something like that ? I will continue to dig into it and see if I can spot something, but I thought it would be nice to share it here too cause that's maybe a potential gate problem.
