I'm running Jupyter notebooks (Python 3) on a remote cluster that I'm connected/tunneled to over SSH.
Jupyter's default behavior is to try to open the dashboard in a web browser when it launches -- aparently (I only just updated), at some point they switched to the Python 3 webbrowser library for this.
According to webbrowser's documentation:
text-mode browsers will be used if graphical browsers are not available or an X11 display isn’t available.
This is exactly what happens. I run jupyter notebook, webbrowser launches elinks, and my one-time authentication token gets eaten, preventing me from connecting to the notebook.
Jupyter isn't configured to use a browser -- c.NotebookApp.browser is commented out in my config -- and running BROWSER="" jupyter notebook doesn't help either.
How can I force Jupyter not to open any browser?
jupyter notebook --generate-config
Then edit ~/.jupyter/jupyter_notebook_config.py and Add
NotebookApp.open_browser = False
