Notebook access in Sage 7.3 via Oracle VM
I am a new Sage user. I have been experimenting with Sage 7.3 on my Windows laptop using Oracle VirtualBox (Version 5.1.6 r110634). When I initialize Sage in Jupyter, the only way I have been able to use the notebook version is to first open a saved Jupyter Sage document I named Initialize_Notebook_Sage.ipynb and then executing the command notebook(). From that point, the application resets (after a short delay) and I have access to previously saved Sage Notebooks with the interface I expected. I tried to access notebooks through a browser using http://localhost:8080, but was unsuccessful.
While this workaround gets me to the desired interface, it is not the most elegant. Is there a way to access the Sage Notebook directly from the Jupyter screen or from the VirtualBox screen?
Thanks in advance for your help.
