Hi Everyone,
I am trying to run Jupyter notebook on remote cluster. After I set up the
ssh tunnel from local machine to the remote cluster, I was able to open
Jupyter using local browser. However, when I tried to start a python 2
notebook. there was an error saying "Unexpected error while saving file:
db/Untitled.ipynb database is locked".
Anyone knows why this happened?
Here are the error messages:
[W 12:03:28.146 NotebookApp] Unexpected error while saving file:
db/Untitled.ipynb database is locked
[E 12:03:28.147 NotebookApp] {
