IOError：无法打开资源

我在 ipython 笔记本上有一段代码，我试图在其中创建词云，但出现错误。据我所知，该错误与其他内容有关，而不是我的代码（带有字体的内容？）

IOError: cannot open resource

我不太确定如何解释这一点。似乎我正在使用的类需要一些字体，并且某些字体文件发生了一些情况。任何见解将不胜感激

我用这个作为基础：http://99projects.co/reports/p05-word-Frequency/ http://99projects.co/reports/p05-word-frequency/

您需要在 wordcloud 对象中指定 font_path。阿穆勒，作者图书馆 https://github.com/amueller/word_cloud在他的最新版本中改变了很多东西。我根据这些变化更新了我的项目，你可以在这里检查 http://99projects.co/updates/u02-dealing-with-library-changes-in-project-05/
