Python 2.7 Scipy-Cookbook-使用特殊值绘制图像-赢得'；行不通

我试图运行Scipy Cook Book中的一个示例，但无法运行它

我使用的是python 2.7（Numpy版本1.6.2，Matplotlib 1.1.1）

代码位于

然而，我得到了一个错误的说法

    Exception in Tkinter callback
    Traceback (most recent call last):

        return self.func(*args)

      File "C:\Python27\lib\site-packages\matplotlib\cm.py", line 214, in to_rgba

通过网络搜索，我找到了一条关于它的评论，但没有什么有用的

希望有人能帮我理解问题，找出错误

可悲的是，食谱中的许多代码已经过时，不再有效。你已经看过numpy部分了。我玩了一点，问题似乎出在第二个图中指定的颜色映射中。如果将其设置为“jet”，则会进行绘图。从您发送的链接来看，自编写该示例以来，colormap创建似乎发生了更改。
