JupyterLab on DGX Spark Dashboard Fails to Start

I’ll start by saying, I unintentionally screwed up the integrated installation of JupyterLab on my user account. Normally, you simply click Start next to JupyterLab on the Dashboard and wait for it to install or start. Mine simply says Jupyter failed to start in the visible output log..

Is there a way to reset that integrated installation of JupyterLab to get it working again for my profile?

I attempted running from a new test user account and that test acount WAS able to start the service. So, the issue is most likely within the scope of my user profile.

Any insight / ideas on how to resolve/reset the integrated version of JupyterLab for my profile without resetting to factory?

Hi, you can reboot the DGX Dashboard or the machine to retry the JupyterLab installation. Can you make sure that the “working directory” you want to start your jupyter notebook in does not exist? There is known issue where JupyterLab will fail if the directory already exists.

@martinro73 please inspect /var/log/dgx-dashboard-service.log and /var/log/dgx-dashboard-service.err.log to see why it fails. To restart the service, when Stop won’t work, run sudo systemctl restart dgx-dasboard-admin.service

To get your Jupyter working again using the DGX-Dashboard delete the previous Working Directory and $USER/.local/share/jupyter
