安装imutils后skimage.io.imsave报参数过多TypeError求助

原本可正常使用skimage.io.imsave保存图像，执行conda install -c conda-forge imutils安装imutils包（同步更新了部分依赖）后，出现如下报错：

TypeError: function takes at most 13 arguments (14 given)

当前调用代码：

path = "img_out.jpg"
io.imsave(path, img, check_contrast=False,quality=100)

解决方案 #

• 回退Pillow版本：报错根源是安装imutils时更新的Pillow版本与现有scikit-image、imageio依赖不兼容。回退到之前能正常工作的版本即可，例如：

  conda install pillow==8.4.0
  

  或用pip：

  pip install pillow==8.4.0
  

  可根据自己之前的环境版本调整具体版本号。

• 指定imsave使用特定插件：在调用io.imsave时显式指定插件，绕开imageio的legacy插件问题，无需修改核心逻辑：

  io.imsave(path, img, check_contrast=False, quality=100, plugin='pil')
  

  也可尝试plugin='matplotlib'，根据实际环境选择可用插件。

• 锁定依赖版本：后续创建conda环境时，在环境配置文件（如environment.yml）中明确指定scikit-image、imageio、pillow的具体版本，避免依赖更新引发冲突。
