Google AI Notebook Jupyterlab won't build with jupytext installed

This is actually more of a support request than bug report.

When I install jupytext via the extension manager in a google ai notebook I get a popup saying that I need to run build. I click on the UI link. Then I get a message that the build failed.

Is this a known problem? Any suggestions?

Actually, when build at the terminal it seems to work:

(base) jupyter@balter-ai-clinvar:~/clinvar-ab$ jupyter lab build
[LabBuildApp] WARNING | Config option `kernel_spec_manager_class` not recognized by `LabBuildApp`.
[LabBuildApp] JupyterLab 1.2.16
[LabBuildApp] Building in /opt/conda/share/jupyter/lab
[LabBuildApp] Building jupyterlab assets (build:prod:minimize)

But still no jupytext manu.

I created another fresh install and it worked! I might write up my steps and put it in a blog post or something. I did need to do things in a very particular order:

1. Create the AI Notebook
2. conda install jupytext -y
3. conda update --all -y
4. jupyter labextension install jupyterlab-jupytext@1.1.1
5. jupyter lab build
6. Restart the AI Notebook

I was worried that if I ran conda update --all again it would move jupytext back up to the latest and require downgrading to 1.1.1 again. I tried it and this did not happen. But I’ll report back if I do run into any problems.

Thanks for your help @mwouts!

Excellent! Thanks for letting us know. Yes you’re right, it is better to explicitely run jupyter lab build. Looking forward to reading your post 👍
