D:\python\Lib\site-packages\graphviz是graphviz库的安装路径。Graphviz是一个用于绘制图形的开源工具集,可以用于绘制各种类型的图形,如流程图、组织结构图、UML图等。它通过定义节点和边来表示图形,并提供了多种布局算法来自动排列节点和边的位置。安装graphviz库后,可以使用它提供的函数和方法来创建和渲染图形。

Requirement already satisfied: graphviz in d:\pyhon\lib\site-packages (0.20.1)
这似乎不是一个问题,而是一个 Python 包的安装提示。graphviz 是一个用于绘制图表的 Python 库,它可以生成各种类型的图表,包括流程图、组织结构图、状态转换图等等。如果您已经安装了 graphviz 包,并且没有遇到任何问题,那么您可以开始使用它来生成所需的图表了。如果您有任何其他问题,请随时问我。

这是一个错误信息,看起来是在渲染决策树图(decision tree)时出现的问题。错误提示说系统找不到指定的文件,可能是 Graphviz 的可执行文件(executable)没有被正确安装或者没有被添加到系统的 PATH 路径中。你可以尝试重新安装 Graphviz 并确保它被正确配置后再尝试渲染决策树图。
