This is most likely an issue with your backend setting. If you want your plots to show up inline (inside of your notebook) import with this added line:

这很可能是您的后端设置的问题。如果您希望您的绘图显示为内联(在您的笔记本内),请使用以下添加的行导入:

import matplotlib.pyplot as plt
%matplotlib inline

To have your plots show up interactively inline (inside your notebook) import with this line instead:

要使您的图表以内联方式(在笔记本内部)以交互方式显示,请使用此行导入:

import matplotlib.pyplot as plt
%matplotlib notebook

To have your plots show up outside of your notebook (in a new window), import with this line instead:

要让您的图表显示在笔记本之外(在新窗口中),请使用此行导入:

import matplotlib.pyplot as plt
%matplotlib qt

NOTE: You need to restart the kernel to switch between inline notebook and outside qt to avoid the error: Warning: Cannot change to a different GUI toolkit

注意:您需要重新启动内核以在内联笔记本和外部qt之间切换以避免错误:警告:无法更改为其他GUI工具包

Finally, if issues persist, the following might help uncover what is going on:

最后,如果问题仍然存在,以下内容可能有助于揭示正在发生的事情:

import matplotlib
matplotlib.get_backend()

If using any of the options above, it should output one of the following:

如果使用上述任何选项,则应输出以下内容之一:

• 'module://ipykernel.pylab.backend_inline'
• 'nbAgg'
• 'Qt4Agg'

Add this in the beginning of your iPython:

在iPython的开头添加:

% pylab inline
