%matplotlib 笔记本显示空白直方图 [英] %matplotlib notebook showing a blank histogram

问题描述

在我的 Jupyter 笔记本中，我现在使用 %matplotlib notebook 而不是 %matplotlib inline，我现在可以在 Jupyter 上与我的绘图进行交互真是太棒了.但是，当我尝试制作直方图时，我得到了一个空白图:

In my Jupyter notebook I am now using %matplotlib notebook instead of %matplotlib inline, it's awesome that I can now interact with my plots on Jupyter. However, when I try to make an histogram I get a blank plot:

如果我使用 %matplotlib inline 一切正常:

If I use %matplotlib inline everything works fine:

怎么回事?

推荐答案

看到我上面的评论确实帮助某人解决了问题，我将其作为答案发布.

Seeing that my comment above has indeed helped someone to solve the problem I will post it as an answer.

如果您从 %matplotlib inline 切换到 %matplotlib notebook 而不重新启动内核，则会出现问题.

The problem occurs if you switch from %matplotlib inline to %matplotlib notebook without restarting the kernel.

从 %matplotlib notebook 切换到 %matplotlib inline 工作正常.

Switching from %matplotlib notebook to %matplotlib inline works fine.

所以解决方案是要么重启内核，要么启动一个新的 notebook.

So the solution is to either restart the kernel or start a new notebook.

似乎在某些情况下，重复笔记本后端的设置会有所帮助，即像调用两次一样

It seems that in some cases it helps to repeat the setting of the notebook backend, i.e. call it twice like

%matplotlib notebook
%matplotlib notebook
