Comment 2 for bug 211030

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:

In [1]: from enthought.mayavi.tools import mlab
Set Envisage to use the workbench UI: True
Set Envisage to use the workbench UI: True

In [2]: mlab.test_contour3d()
