Python 属性错误：'；numpy.ndarray和#x27；对象没有属性'；如"rgba"str和"x27 ;；

我是一个新手程序员，我的直觉是这个错误是由于某种安装或版本问题造成的，但我不知道是什么原因。我在OS 10.8上运行python 2.7，今天刚刚安装了numpy 1.12.0和matplotlib-1.5.1，试图构建热图

我正在尝试从matplotlib站点（）运行此示例：

matplotlib站点中的其他类似示例也表现出类似的行为。 当然，请让我知道这是否是重复的（我试图搜索答案，但没有找到任何类似于我的问题，但我也可能不知道搜索什么）

如果是安装错误，请提供有关如何修复该错误或正确方向上的点的详细说明。谢谢大家!

编辑：以下是错误前的回溯：

我无法修复您的问题，但我可以告诉您这是一个安装问题，您发布的代码在我使用Python2.7进行的安装中运行良好。虽然我使用的是windows而不是IOS

肯定是某种安装错误，但我安装了Anaconda，问题得到了解决。对于将来发现这个问题的人来说，ActivePython没有numpy或scipy。

，因为_rgba_str

是一种

图像的方法；您应该显示一些发生错误的堆栈（行）。这可能会让你知道你的安装中缺少了什么。是的，这正是我害怕的。谢谢你帮我检查！如果它变得太令人沮丧，我将切换到我实验室的linux机器。您是否尝试过安装直接随这些科学模块一起提供的python版本？尝试使用其中一个版本重新安装python会导致任何问题吗？我应该先卸载当前的python发行版吗？是的，否则在尝试安装时可能会收到警告。此外，如果您当前使用的是2.7，则无需转到python的更高版本
