Jupyter matplotlib 畫圖就kernel died 問題解決

 

jupyter一畫圖就卡死， 類似下面的代碼，運行會導致 kernel died

 

 

 

 

 

運行如上所示的代碼，沒有圖形出來。實際上看jupyter的log，kernel已經died了 日志如下；

看到一篇文章：

 

kernel dead

用pytorch學習深度學習，運行老師給的代碼，每次遇到要畫圖的環節，jupyter notebook一言不合就內核掛掉了…

 

試錯

全網找解決方案，jupyter、ipkernel什么的全都是最新版本，anaconda分配內存、docket分配內存啥的全都試了一遍…試了整個晚上，都沒有用。。心累

 

解決方案

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

 

 

我最開始freetype沒有限定版本， conda install --yes freetype 還是報錯。按照上面的限定了版本號 2.10.4 。就解決問題了。

 

Matplotlib依賴freetype庫。
