I've never used Jupyter, so I don't know much about it. You might be able to plug your phone into your PC and access the notebook from your phone's storage. You might also be able to run a file server on your phone and access it wirelessly that way, but that would take a lot more setup.
If you have ios you're in luck its pretty simple get the Juno app https://apps.apple.com/app/juno-jupyter-notebook-client/id1315744137 for android its more involved .. Option 1 - get pydroid https://play.google.com/store/apps/details?id=ru.iiec.pydroid3 Use pip to install jupyter (just type the name jupyter) (pip should be in the 3 dot menu) click/tap the terminal icon and type jupyter notebook Option 2 - is who whole hell of complicated https://www.leouieda.com/blog/scipy-on-android.html Hope that helped. You also have another option which I use is to just remote shell into a desktop or the like, I just find that far more reliable as it is inside a proper desktop OS environment Update - I just noticed you have Termux labeled in your tags lol ... so you are probably on android and aware of the method i linked. Better try Option 1.... But if that doesnt work, and or option 2 is necessary, What is the specific issue?
