Python Jupyter笔记本内核在尝试运行matplotlib时死机

一般来说，我对Python和编程非常陌生。我试图在Jupyter笔记本中使用matplotlib绘制一个简单的图形，但错误消息不断弹出，说内核已经死了。我试过重新安装水蟒和朱皮特。我也尝试过“conda install nomkl”，但问题仍然存在。下面是一些屏幕截图

这是我的终端窗口的副本：

首先尝试执行matplotlib导入。通常，当您遇到这样的错误时，请逐行执行代码，看看是哪一行导致了错误。从您的屏幕截图中，我们无法判断问题是由导入还是打印引起的，因为两者位于同一个笔记本单元中。顺便说一句，您不需要在笔记本中使用

plt.show（）

。我尝试只运行导入，内核可能是硬件问题？您可以尝试在不使用笔记本的情况下从shell运行matplotlib导入行吗？首先尝试执行matplotlib导入。通常，当您遇到这样的错误时，请逐行执行代码，以查看哪一行导致错误。从您的屏幕截图中，我们无法判断问题是由导入还是打印引起的，因为两者位于同一个笔记本单元中。顺便说一句，您不需要在笔记本中使用
