关于Matplotlib实验中出现NameError: name ‘rgb2gray‘ is not defined的解决

唉,这个问题搞了老半天!!!

废话少说,直接上解决方案:1:终端pip install install scikit-image

                                            2:python项目中from skimage.color import rgb2gray

        完美解决!!!

以下是解决经历:

看的matplotlib显示图像实验中引用了marplotlib.pyplot后直接使用rgb2gray函数,但自己用时就出现了NameError: name 'rgb2gray' is not defined的错误。

翻找了很长时间发现是缺少一个库

大佬kakaccys在一个问题下评论需要加上:from skimage.color import rgb2gray

我直接去pip但是又出现了

  note: This error originates from a subprocess, and is likely not a problem with pip.

[notice] A new release of pip available: 22.2.1 -> 22.3.1

看到Please install the 'scikit-image'packge

pip了这个全称结果就可以了
