Hi,
I have the contorno.py plot that I get from the:
http://docs.enthought.com/mayavi/mayavi/auto/example_contour.html
I did:
python contorno.py
and I had:
Warning: Unable to import the wx backend for pyface due to traceback:
Traceback (most recent call last):
File
"/usr/lib/python2.7/site-packages/pyface-4.5.2-py2.7.egg/pyface/toolkit.py",
line 49, in _init_toolkit
be = import_toolkit(tk)
File
"/usr/lib/python2.7/site-packages/pyface-4.5.2-py2.7.egg/pyface/toolkit.py",
line 31, in import_toolkit
__import__(be + 'init')
File
"/usr/lib/python2.7/site-packages/pyface-4.5.2-py2.7.egg/pyface/ui/wx/init.py",
line 14, in <module>
import wx
ImportError: No module named wx
What can I do to solve this.
