[vmtk-users] pype error

[adrianrh <adr...@st...>]

Hi!

I have tried reinstalling vmtk several times, but I keep getting this 
error when running any command. Is there something wrong with my 
installation? or maybe the python installation?

$ vmtklevelsetsegmentation -ifile image_volume.vti

Error from pype: cannot concatenate 'str' and 'exceptions.ImportError' 
objects
