導入matplotlib.pyplot時Python崩潰

Question

我試圖從matplotlib導入pyplot使用： import matplotlib.pyplot as plt

我收到以下錯誤，終止我的python程序。

我的代碼最近在我運行El Capitan的舊MacBook Pro 2012上運行。 我現在正在使用High Sierra的2017 Macbook Pro上運行...不知道這是否與它有任何關系。 我嘗試使用pip卸載並重新安裝Matplotlib，但仍然遇到同樣的問題。 我正在使用anaconda安裝的Python。 感謝幫助！

編輯：當我將Matplotlib的后端更改為'Agg'而不是'TkAgg'時，我沒有得到上面的錯誤，程序運行但數字不顯示。

Answer 1

我在這篇文章中找到了解決方案（ Anaconda Runtime Error：Python沒有作為框架安裝？ ）

我卸載了matplotlib： pip uninstall matplotlib

然后使用anaconda重新安裝它： conda install matplotlib

這似乎解決了所有問題，程序正如以前一樣運行。
