我在ipython笔记本上有一个代码,我试图制作一个wordcloud,但是我收到了一个错误。从我所看到的,错误与其他东西有关,而不是我的代码(有字体的东西?)

我不太清楚如何解释这一点。看起来像我使用的类需要一些字体,而某些字体文件会发生一些事情。任何见解将不胜感激

您需要在wordcloud对象中指定font_path。 the library的作者Amueller在他的最新版本中改变了很多东西。我根据这些更改更新了我的项目,您可以check it here
答案 1 :(得分:0)
在Mac OS X上,我收到了错误:
IOError: cannot open resource
我更改了文件中的FONT_PATH&#34; wordcloud.py&#34;
FONT_PATH = os.environ.get("FONT_PATH", "/Library/Fonts/Times New Roman.ttf")
错误就消失了。
答案 2 :(得分:0)
在Mac OS X上,出现错误:
IOError: cannot open resource
我在文件“ xxx.py”中更改了FONT_PATH
wc = WordCloud(
max_words=100,
width=2000,
height=1200,
font_path = 'Hiragino Sans GB.ttc'
)
可能会正确!
