Jupytermatplotlib画图就kerneldied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；

exited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

最后我在
在stackoverflow上⾯到了答案：
I try the solution of this , based on this , 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。
