将wxpython与Mayavi一起用于UI，会在"decorated_scene.py“文件中抛出错误

Question

我运行了一个python程序，它使用Mayavi来显示地理参考的DEM(数字高程模型)。它在Anaconda环境下运行非常好。但是，在windows上运行时，需要为UI安装PyQt/PySide/wxpython (显示3D模型)。

在运行代码时，它开始抛出此错误。

wx._core.wxAssertionError: C++ assertion "strcmp(setlocale(0, 0), "C") == 0" failed at ..\..\src\common\intl.cpp(1694) in wxLocale::GetInfo(): You probably called setlocale() directly instead of using wxLocale and now there is a mismatch between C/C++ and Windows locale.
Things are going to break, please only change locale by creating wxLocale objects to avoid this!

我建议this 1和this 2通过在代码开头包括以下内容来解决这个错误

import locale
locale.setlocale(locale.LC_ALL, 'C')

还有另一个错误。此错误是由于文件_C:\Python38\lib\site-packages\tvtk\pyface\ui\wx_decorated_scene.py中的命令m.set_outline_color(1,1,1)与当前版本的wx不兼容造成的。

错误：

解决办法如下：

Answer 1

开放_C:\Python38\lib\site-packages\tvtk\pyface\ui\wx_decorated_scene.py.

找到这一行m.set_outline_color(1,1,1)并将其替换为m.outline_color = (1,1,1)

完事了！
