我正在开发一个使用Mayavi软件包的桌面应用程序。所以，我使用anaconda与mayavi 4.4.0和pyqt 4.11.3（python 2.7）。当我尝试使用Mayavi界面保存图像时，我得到：
KGlobal::locale(): Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work

我修复了编辑*.py文件的其他问题，我不知道如何解决这个问题。
