％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，我现在使用的是%matplotlib notebook而不是%matplotlib inline，现在可以与我在Jupyter上的绘图进行交互了.但是，当我尝试制作直方图时，会得到一个空白图:

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，则一切正常:

If I use %matplotlib inline everything works fine:

这是怎么回事?

推荐答案

看到我上面的评论确实帮助某人解决了问题，我将其发布为答案.

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

如果在不重新启动内核的情况下从%matplotlib inline切换到%matplotlib notebook，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可以正常工作.

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

因此解决方案是重新启动内核或启动新笔记本.

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

在某些情况下，它似乎有助于重复笔记本后端的设置，即像这样两次调用它

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
