wx.Image is throwing PyAssertionError

问题

I ran the following python code

import wx

class myframe(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, -1, title="Hello")
        self.InitUI()

    def InitUI(self):

        menubar = wx.MenuBar()
        fileMenu = wx.Menu()
        qmi = wx.MenuItem(fileMenu, 100, '&Quit\tCtrl+Q')
        qmi.SetBitmap(wx.Image('quit.png', wx.BITMAP_TYPE_ANY).ConvertToBitmap())
        fileMenu.AppendItem(qmi)

        self.Bind(wx.EVT_MENU, self.OnQuit, id=100)

        menubar.Append(fileMenu, '&File')
        self.SetMenuBar(menubar)

        self.SetSize((250, 200))
        self.SetTitle('Icons and shortcuts')
        self.Centre()
        self.Show(True)

    def OnQuit(self, e):
        self.Close()

def main():
    ex = wx.App()
    myframe()
    ex.MainLoop()

if __name__ == '__main__':
    main()

The above code is throwing the message

qmi.SetBitmap(wx.Image('quit.png', wx.BITMAP_TYPE_ANY).ConvertToBitmap())
  File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\_core.py", line 2882, in __init__
    _core_.Image_swiginit(self,_core_.new_Image(*args, **kwargs))
PyAssertionError: C++ assertion "strcmp(setlocale(LC_ALL, NULL), "C") == 0" failed at ..\..\src\common\intl.cpp(1449) 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!

I am new to python and completely unable to solve this. Is there anyway to find the solution to this.

I am using python 2.7.10 and wxpython 3.0.2.0 in a windows machine.

回答1:

I had a similar issue that only occurred following a cxFreeze with wxPhoenix. I worried that the solution above could cause issues on a machine that wasn't wx.LANGUAGE_ENGLISH, so instead, I recorded the locale before any imports (which I suspected were changing the locale):

import wx
locale = wx.Locale.GetSystemLanguage()

And then reset it after my imports and after creating the app:

app = wx.App(redirect=False)
app.locale = wx.Locale(locale)

This worked for me.

回答2:

The solution is to modify the locale and it is working. Modified the code as here:

def main():
    ex = wx.App()
    ex.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
    myframe()
    ex.MainLoop()

Locale is conflicting with system locale. So modified it in the code for this program.
