ModuleNotFoundError after pip install notebook==7.0.0

[keejiu]

I upgrade notebook to V7 by pip install notebook==7.0.0a17.
I typed jupyter notebook in Mac terminal as usual but error occurs saying ModuleNotFoundError: No module named 'notebook.notebookapp'.
Anyone know how to deal with it? I have to reinstall notebook 6.5

Thanks @KayjiYu for trying out the Notebook 7 pre-release 👍

It looks like it could be an issue with the terminal not finding the right command for starting the application.

Did you try to install v7 in a new virtual environment?

Thanks for your advice!

I created a virtual environment and installed notebook 7.0.0a18, it works!

However it seems that some packages are not compatible with notebook V7, for example, Jupyterthemes. I'm still being used to the built-in dark mode.

Anyway, v7 works well so far. Thank you so much.

Thanks again for trying the pre-release!

For reference it's possible to use existing JupyterLab themes like JupyterLab Dark (built-in) or JupyterLab Night (third-party):

I opened #6805 to track adding this to the documentation.

However it seems that some packages are not compatible with notebook V7, for example, Jupyterthemes. I'm still being used to the built-in dark mode.

Also the author of https://github.com/dunovank/jupyter-themes has ported some themes for JupyterLab, which should work in Notebook 7:

• https://github.com/dunovank/jupyterlab_legos_ui
• https://github.com/dunovank/jupyterlab_darkside_ui

Thanks a lot!

I have been trying the darkside_ui as well as the jupyterlab built-in dark mode. They are okay but my personal preference is still 'onedork' which is not available right now. Never mind ! I'm getting used to them!

Thank you again for following up with the simple inquiry ! I'm enjoying the notebook 7.

They are okay but my personal preference is still 'onedork' which is not available right now.

There seems to be a One Dark Pro theme available though, not sure how similar to onedork it is: https://github.com/johnnybarrels/jupyterlab_onedarkpro

Closing as answered. I opened #6813 to improve the documentation about migrating to Notebook 7, and documenting the topic of themes there.

Thanks again!
