    x = linspace(-10., 10., 1000)
    plot(x, sin(x))

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! 

我试图绘制结果。我如何绘制结果？我收到了PyAssertion错误。我该如何解决错误？
