Execute time not showing in notebook with time stamps in the metadata

Hello,

I’m having issues getting this extension to work. I’ve tried my best to follow the instructions in the README using pip install jupyterlab_execute_time and making sure that I to enable cell timing in the notebook via Settings->Advanced Settings Editor->Notebook: {"recordTiming": true}.

The software versions that I’m using are

$ jupyter --version jupyter core : 4.7.1 jupyter-notebook : 6.3.0 qtconsole : 5.0.3 ipython : 7.22.0 ipykernel : 5.5.3 jupyter client : 6.1.12 jupyter lab : 3.0.14 nbconvert : 6.0.7 ipywidgets : 7.6.3 nbformat : 5.1.3 traitlets : 5.0.5

jupyterlab-execute-time : 2.0.2

I don’t know if this is an issue with the M1 Apple Silicon. I’m running macOS 11.3 and I installed Python 3.9.4 with brew.

The metadata is being recorded correctly, because the time stamps and wall times show up correctly when I open the notebook on a different machine that also uses juypterlab-execute-time. So it is not like this issue. It’s a new installation of JupyterLab v3.0.14, so I don’t think I have any holdover issues like this one. I tried running jupyter labextension enable jupyterlab-execute-time, but nothing changed, and when I list the extensions I’m using it doesn’t return anything.

$ jupyter labextension list JupyterLab v3.0.14

I know there are a lot of issues and stackoverflow questions that have been opened involving the time not showing. This is the only extension that I use and I really appreciate the work that’s been put into it. I’d be grateful for any help or insight. Let me know what kind of details you may need.

Thank you

Glad it works. Closing.

Thank you! The development install process is working.

I had previously installed nodejs using brew. I followed the developer install process in the README by doing the following starting in the jupyterlab-execute-time folder:

jlpm jupyter labextension develop . --overwrite jlpm run build

I then restarted JupyterLab.

The console log now says

[Debug] Starting application in workspace: “default” (jlab_core.26a554263e541eb0c66a.js, line 2) [Log] JupyterLab extension jupyterlab-execute-time is activated!

and the time stamps and execution time now show up for each cell.

Thanks again for the help. I’m not sure why the pip install jupyterlab_execute_time didn’t install correctly, but the developer installation is installed and seems to be working correctly.
