WordCloud生成报错：'TransposedFont'无'getbbox'属性的解决咨询

问题描述 #

我运行以下代码生成词云：

text = 'word1 word2 word2 word3 word3 word3'

from wordcloud import WordCloud

wordcloud = WordCloud(width=480, height=480).generate(text)

在Jupyter Notebook中得到完整错误栈：

AttributeError: 'TransposedFont' object has no attribute 'getbbox'

我未在WordCloud函数中使用过TransposedFont相关参数，请问该错误是什么原因，如何解决？

错误原因与解决方法 #

错误原因 #

这个报错是wordcloud库与PIL（Pillow）库版本不兼容导致的：

• 新版Pillow调整了字体相关API，TransposedFont对象不再提供getbbox方法；
• 旧版本wordcloud仍在调用这个已被移除的方法，从而触发AttributeError。

解决方法 #

有两种可行的修复方式：

• 方法1：升级wordcloud到兼容版本
  执行以下命令更新wordcloud，新版本已适配Pillow的API变更：

  pip install --upgrade wordcloud
  

• 方法2：降级Pillow到兼容旧版
  如果暂时不想升级wordcloud，可将Pillow降级到9.5.0版本（该版本与旧版wordcloud兼容）：

  pip install pillow==9.5.0
