Can't access to my notebooks!

Two days ago I installed NBgrader extensio and since then I can’t see my notebooks. It seems like they are open but in the parte of the screen where I must see my notebooks only see a blank area.
Please, help… How can I uninstall the extension?

Hi Manuel,

How exactly did you install NBGrader? Using the terminal or the JupyterLab Extension from the Extensions manager.

Could you try running pip uninstall nbgrader and see if that solves the issue?

Failing that, please provide the full URL that contains the long userID and we can take a closer look at the system packages and try to reset them back to defaults.


Hi Jack. I had just done that when I read your response, uninstalling nbgrader made everything work normally again. I don’t know if it can’t be used or if there is an alternative to nbgrader.
Thanks for your answer.
