matplotlib - 導入錯誤：沒有模塊名爲_tkinter

Question

我有一個簡單的筆記本用下面的代碼：

%matplotlib inline 

但是，在運行時，我收到以下錯誤：

ImportError: No module named _tkinter 

我還有一個筆記本在同一個項目中，並且能夠毫無問題地運行該聲明。

數據科學體驗是一種託管服務，因此您沒有root訪問權限來安裝_tkinter。

Answer 1

所以修復是相當簡單 - 我只是用在筆記本內核菜單項來重新啓動內核。

我在我的筆記本電腦上本地運行ipython時遇到了同樣的問題，解決方案是安裝tkinter，所以我沒有想到答案與重新啓動內核一樣簡單。

另一次我收到這個錯誤信息，重新啓動內核不起作用。我只好：

• 變化火花後端
• 下載筆記本文件
• 刪除筆記本DSX
• 創建從下載的筆記本
