Python WordCloud 仅支持 TrueType 字体

发布于04月29日

我正在try 使用Python中的wordCloud模块生成一个单词云，但是每当我调用.generate时，我都会看到以下错误

Traceback (most recent call last):
  File "/mnt/6db3226b-5f96-4257-980d-bb8ec1dad8e7/test.py", line 4, in <module>
    wc.generate("foo bar foo bar hello world")
  File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 639, in generate
    return self.generate_from_text(text)
  File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 621, in generate_from_text
    self.generate_from_frequencies(words)
  File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 453, in generate_from_frequencies
    self.generate_from_frequencies(dict(frequencies[:2]),
  File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 508, in generate_from_frequencies
    box_size = draw.textbbox((0, 0), word, font=transposed_font, anchor="lt")
  File "/usr/lib/python3/dist-packages/PIL/ImageDraw.py", line 671, in textbbox
    raise ValueError("Only supported for TrueType fonts")
ValueError: Only supported for TrueType fonts

现在，我正在try 创建一个非常简单的示例wordCloud

import matplotlib.pyplot as plt
from wordcloud import WordCloud
wc = WordCloud(background_color="white", font_path="./arial.ttf", width=800, height=400)
wc.generate("foo bar foo bar hello world")
plt.axis("off")
plt.imshow(wc)
plt.savefig("test.png")
plt.show()

其中arial.ttf是从https://www.freefontspro.com/14454/arial.ttf下载的，并且放置在与test.py相同的目录中.我使用的是Ubuntu 22.04和Python3.10.6.

我原本希望从输入"foo bar foo bar Hello world"生成一个单词云，但是看到错误ValueError: Only supported for TrueType fonts，尽管向font_path参数传递了一个TTF.

任何帮助解决这一问题的人都将不胜感激！
