分步解决方法 #

• 第一步：在Colab新建一个单元格，运行以下命令卸载当前版本的Pillow：

  !pip uninstall -y pillow
  

• 第二步：安装兼容的旧版本Pillow（9.5.0版本可适配VQGAN+CLIP的依赖需求）：

  !pip install pillow==9.5.0
  

• 第三步：重启Colab运行时：点击页面顶部「Runtime」菜单 → 选择「Restart runtime」
• 第四步：重新运行「Loading libraries and definitions」单元格

问题原因 #

最新版本的Pillow（Python图像处理库）移除了VQGAN+CLIP代码依赖的isDirectory方法，安装指定旧版本即可匹配代码的依赖要求。
