Problem with mayavi #652

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I installed in my notebook the pythonxy and I´ve tried using mayavi. 
I'm not having success because any example I run, python gives the following 
error:

What should I do? 
I'm using windows 7 32-bit spyder2.
Thanks,

Please make sure you have wx installed. That is the most stable and best 
supported backend for it.

How can i verify if wx was installed?
There is a folder, isn't?

Open the XY launcher and see if wxPython is installed.

I have the wxPython-version 2.8.12.
When I've used spyder IDE an error appears like that i posted.
But if I've used mayavi as applications in XY launcher that's OK!
I don't understand what is happening.

I cannot start using mayavi2 using spyder IDE from pythonxy.
What should i do?
The mayavi2 is working well, but i really want to use mayavi in spyder?
Suggestions?
Thanks.

Use Spyder preferences to set QString API to 2 - 
Tools -> Preferences -> Console -> External Modules Tab -> Default API -> API #2

Thanks for help!
It's working!
Just remembering: Spyder must be restarted after changed Preferences.
