jupyterlab-执行时间

首先启用扩展管理器

然后你必须重新启动内核

你仍然发现你看不到你想要的东西:

最后recordTiming"=true

并保存在右端！

In jupyter notebook, I can configure an automatic cell timing with nbextensions, the result is like so:

How can I do this in jupyter lab? I didn't find any extensions that do a similar thing.

Obs.: I know that a similar result can be achieved with %%time magic, but I want it to be automatic, so I don't have to place the magic function at the beginning of each cell.

解决方案

Requirement

JupyterLab >= 2.0.2

Let's move step by step

Extension availabel in jupyter lab is

jupyterlab-execute-time

first enable extension Manager

after enable you see new button in side task bar at the end "extension Manager"

You can also enable it with the following steps:

1. Go into advanced settings editor.
2. Open the Extension Manager section.
3. Add the entry "enabled": true.
4. Save the settings. If prompted whether you are sure, read the warning, and click "Enable" if you are still sure. Once enabled, you should see a new tab appear in the left sidebar

By default, the disclaimer is not acknowledged.

As the disclaimer is not acknowledged, you can search for an extension, but can not install it (no install button is available).

To install an extensino, you first have to explicitly acknowledge the disclaimer. Once done, this will remain across sessions and the user does not have to check it again.

Finding Extension

search jupyterlab-execute-time

Install Enable

After enable you have to Rebuild it: A small popup window open on it click on Rebulid;

then you have to restart kernel

Still you find you will not able to see what you want :

Last thing

Note: for this to show anything, you need to enable cell timing in the notebook via Settings->Advanced Settings Editor->Notebook: {"recordTiming": true}

advance setting editor

finally "recordTiming"=true

and save it at right end!
