Spyder hint Valueerror:api ' QString ' have already been set to version 1

Reprinted from: http://wuyuans.com/2013/02/spyder-valueerror-api-qstring-has-already-been-set-to-version-1/

The use of Enthought.mayavi in Ipython is normal, but there are problems in the Spyder, as follows:

ValueError: API ‘QString‘ has already been set to version 1

The problem is in import here,

from enthought.mayavi import mlab

Because Enthought uses the API #2 when calling PYQT, the Spyder uses the API #1 by default and changes him to an API #2即可.

Open Tools-Preferences, choose Console on the left, open the External Modules tab on the right, find pyqt below, put the API selection for QString and qvariant Object: Changed to API #2, OK, it is normal to run again.
