Comment 4 for bug 1718576

Requirement.parse('networkx<2.0,>=1.10'), {'pypowervm'})
Requirement.parse('networkx<2.0,>=1.10'), {'diskimage-builder'})
Requirement.parse('networkx<2.0,>=1.10'), {'taskflow'})

we don't control the pypowervm project unfortunately, but diskimagebuilder and taskflow should still start.
