Jupyter matplotlib 画图就kernel died 问题解决

 
jupyter一画图就卡死， 类似下面的代码，运行会导致 kernel died
 
 
 
运行如上所示的代码，没有图形出来。实际上看jupyter的log，kernel已经died了 日志如下；

看到一篇文章：
 
kernel dead
用pytorch学习深度学习，运行老师给的代码，每次遇到要画图的环节，jupyter notebook一言不合就内核挂掉了…
 
试错
全网找解决方案，jupyter、ipkernel什么的全都是最新版本，anaconda分配内存、docket分配内存啥的全都试了一遍…试了整个晚上，都没有用。。心累
 
解决方案

在stackoverflow上面找到了答案：

I try the solution of this video, based on this post, and it worked for me:
  • Run Anaconda Prompt as administrator
  • conda install --yes freetype=2.10.4
 
 
我最开始freetype没有限定版本， conda install --yes freetype 还是报错。按照上面的限定了版本号 2.10.4 。就解决问题了。
 
Matplotlib依赖freetype库。
