引入了一个非标准的库，media

执行最后一代命令时报错了

import media 
f = media.choose_file ()
pic = media.load_picture (f)
media.show(pic)

报错信息如下：

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    media.show(pic)
  File "C:Python27libsite-packagespygraphicsmedia.py", line 76, in show

由于以后还要经常用到media这个库，所以很想解决这个问题。 Google了很多，不少人都在求解答
