Import error when executing Mayavi2

After installing Mayavi2 and all its dependences I am unable to run it . I get the following output when executing the commando "mayavi2":

`Traceback (most recent call last):
File "/usr/bin/mayavi2", line 25, in
from mayavi.__version__ import __version__
ImportError: cannot import name __version__`

After unistalling and reinstalling everything a couple of times I do not know what to do. Does anyone has an idea about what is happening?
