Jan Stránský proposed the following answer:
Thanks for more details

> self.cumulativeData = dict((a,0) for a in range(2,10))

here you tell that you only want to store bodies with ids in
range(2,10)...

> vtk.exportSpheres(...)

... but exportSpheres exports all spheres by default, resulting in the
error

You can (depending on your needs):

a) limit the export to the range:
vtk.exportSpheres(ids=list(range(2,10)),...)

b) return some artificial value for not-stored bodies:
class SomeCalculator:
   ...
   def getCurrent(self,b): # the same modification for getCumulative
         return self.currentData.get(b.id,0) # 0 is the "default" value for not-stored bodies, can be anything else

cheers
Jan
