如何分析Kivy应用程序？

我正在使用Kivy构建游戏。我遇到性能问题，所以我决定介绍该程序。如何分析Kivy应用程序？

我试图运行它：

python -m cProfile main.py

应用屏幕保持黑色。几秒钟后，一个异常导致程序崩溃：

Traceback (most recent call last): 
    File "c:\python27\Lib\runpy.py", line 162, in _run_module_as_main

这究竟是为什么，以及如何分析我的Kivy应用程序？

kivy文档声明您不能从命令行执行此操作。

https://kivy.org/docs/api-kivy.app.html

你可以做到这一点是这样的：（从文档复制）

import cProfile 

class MyApp(App): 
    def on_start(self): 
     self.profile = cProfile.Profile() 
     self.profile.enable() 

    def on_stop(self): 
     self.profile.disable() 
     self.profile.dump_stats('myapp.profile')
