运行编译的Python脚本时出现问题

因此，我使用py2exe根据编译了一个python脚本。编译过程中没有错误，一切正常

当我从cmd运行脚本时，如下所示：

C:\Users\Richard\Dist\backprop3.exe 60

这是我得到的输出：

C:\Users\Richard>C:\Users\Richard\Dist\backprop3.exe 60
Traceback (most recent call last):
  File "backprop3.py", line 209, in <module>
  File "backprop3.py", line 175, in demo
NameError: global name '__file__' is not defined

C:\Users\Richard>

---

该行仅从当前目录加载图像。问题出在哪里？

\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。这是因为该模块位于.exe内，因此没有可设置的python文件

有关处理此问题的技巧，请参阅

image = Image.open( os.path.dirname( os.path.abspath( __file__ ) )+"/backprop-input.bmp" )
