I managed to import mlab with In [1]: from enthought.mayavi.tools import mlab as suggested here http://gael-varoquaux.info/blog/?p=3
I get the following errors:

Can you give us more information. In particular how you installed mayavi
(if you indeed did install it using the package, could you check the
version of your package). Can you also give us the traceback in FBI
(there is a tab called "traceback", you can copy and paste it in here).

Finally, can you please test mayavi without the interface. To do this,
you can run "ipython -wthread" (using the package "ipython"), and enter:

from enthought.mayavi import mlab
mlab.test_contour3d()

You should see a window poping up with a visualisation. If you don't,
could you please post the traceback here.

Cheers,

Gaël
