IOError: cannot open resource

问题

I have a code on ipython notebook where I am attempting to make a wordcloud, but I get an error. From what I could see, the error is related to something else and not my code (something with fonts?)

IOError: cannot open resource

I'm not so sure as to how to interpret this. Seems like a class I'm using needs some fonts, and something happens with some font files. Any insight will be appreciated

I am using this as a base: http://99projects.co/reports/p05-word-frequency/

回答1:

You'll need to specify a font_path in your wordcloud object. Amueller, the author of the library changed a lot of things in his latest version. I updated my project according to these changes, you can check it here

回答2:

On a Mac OS X, I've got the error:

IOError: cannot open resource

I changed the FONT_PATH in the file "wordcloud.py"

FONT_PATH = os.environ.get("FONT_PATH", "/Library/Fonts/Times New Roman.ttf")

And the error goes away.
