Please provide a more detailed explanation of what your difficulties 
are. Are you able to run the corresponding static problem?

You are getting this because PyLith could not find a nodeset called 
"magma_chamber" in your mesh file. Make sure you create nodesets in your 
mesh for all groups of vertices where you want boundary conditions, etc.
