I'm using ubuntu 12.04 and python 2.7.3-0ubuntu2 is already installed. I have a problem during installing mayavi2 from ubuntu software center.

Error message is :

Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

Details:

The following packages have unmet dependencies

mayavi2: Depends: python-numpy (>= 1:1.6.1) but 1:1.6.1-6ubuntu1 is to be installed Depends: python-numpy-abi9 but it is a virtual package Depends: python (< 2.8) but 2.7.3-0ubuntu2 is to be installed Depends: python-vtk (>= 5.4.2-5) but 5.8.0-5 is to be installed

I've searched to solve this problem for a long time but I didn't solve yet. What can I do?
