英文:
Graphs are no longer displayed in the output of Jupyter Notebook cells (on Visual Studio Code). How to solve this problem?
问题
自从昨天开始，在我运行在Visual Studio Code上编写的Jupyter笔记本中的Python代码时，单元格输出中不再显示图形。相反，只显示一行文本。例如：<IPython.core.display.Javascript object>。
我认为我在Visual Studio Code的设置中不知不觉地更改了一些内容。然而，我找不到任何方法来解决这个问题。
我已经多次重新启动了Visual Studio Code和我的计算机，并尝试了不同的内核，但什么都没有改变。
我尝试通过点击单元格输出左侧的“更改呈现”然后选择“image/png”作为“mimetype”来解决这个问题，但是我无法选择“image”，因为它不在“mimetype”列表中。
一个不再显示图形的单元格输出示例。
在出现此问题之前，这段代码是有效的。
非常感谢您提前的帮助！
英文:
Since yesterday no more graph appears in the cell output when I run my Python codes written as Jupyter notebook on Visual Studio Code. Instead, only one line of text is displayed. For example :
<IPython.core.display.Javascript object>.
I think I changed something without realizing it in the settings of Visual Studio Code. However, I couldn't find anywhere how to solve this problem.
I restarted Visual Basic and my computer several times and used different kernels, but nothing changed.
I tried to solve the problem by clicking on "change presentation" left to the cell output and then to elect "image/png" as "mimetype", but I can't select "image" as it is not in the list of "mimetype".
Example of a cell output where the graph is no longer displayed.
The code was working before this issue.
Thank you very much in advance for your help!

似乎你的ipython出了一些问题。
你可以尝试在终端中使用以下命令重新安装ipython：
pip uninstall ipython
pip install ipython

问题出现在我的代码开头的“%matplotlib notebook”语句。
经过一些调查，我发现Visual Studio Code不支持“%matplotlib notebook”语句。
这个语句在Jupyter笔记本中用于启用交互式图形功能，例如使用鼠标在空间中移动3D图形的能力。
要解决这个问题，只需在Visual Studio Code中使用“%matplotlib widget”代替“%matplotlib notebook”。
英文:
The problem came from the "%matplotlib notebook" statement at the beginning of my code.
After doing some investigation, it occurred to me that the "%matplotlib notebook" statement is not supported by Visual Studio Code.
This statement is used in jupyter notebooks to enable interactive graphics features such as the ability to move a 3D graphic in space with the mouse.
To solve this problem, just use "%matplotlib widget" instead of "%matplotlib notebook" on Visual Studio Code.
