How to start sage with jupyter notebook listening on port 1234

[ph h]

Hi,

~/sage-9.6/b01$ ./sage --notebook --help

usage: sage-notebook [-h] [--log LOG] [--notebook [NOTEBOOK]]

The Sage notebook launcher is used to start the notebook, and allows
you to choose between different implementations. Any further command
line options are passed to the respective notebook.

optional arguments:
  -h, --help            show this help message and exit. Can be combined with "--notebook=[...]" to see notebook-
                        specific options
  --log LOG             one of [DEBUG, INFO, ERROR, WARNING, CRITICAL]
  --notebook [NOTEBOOK], -n [NOTEBOOK], -notebook [NOTEBOOK]
                        The notebook to run [one of: default, ipython, jupyter, jupyterlab, export]. Default is
                        jupyter

EXAMPLES:

* Run default notebook on port 1234. Note that the first argument
  after "-n" will be interpreted as notebook name unless you stop
  processing with "--":

      sage -n default port=1234
      sage -n -- port=1234      # equivalent
      sage -n port=1234         # ERROR: invalid notebook name

Did I miss something in the attached screen capture?

Thank you for your help.

Regards,

phiho

The correct syntax is
sage -n --port 1234
(no space between -- and port, because --port is just an option name)

it seems to be a doumentation error that one needs a space.

Hi,

Thank you so much for the information. I should have guessed that standard syntax.

Now I can run different versions of sage concurrently through the jupyter notebook.

Your help is much appreciated.

If you do not care about choosing the port number, when you run

    ./sage -n jupyter

and port 8888 is already used, a new Jupyter starts on port 8889,

and so on.

Hi,

Thank you for your sharing but it seems not working on my machine.

Please find attached a series of 5 screen capturing these steps:

1/- For sage in versions (9.4 9.5 9.6B01): 

          ./sage -n (in appropriate console, top to bottom)

          open jupyter notebook (with url shown in console)

          version() shows 9.4 (in all 3 notebooks)

          (also note that only sage 9.4 console was active)

         

2/- Kill sage 9.4 with Control-C in the corresponding console

          9.5 console became active

3/- Restarting notebooks for 9.4, 9.5,9.6B01 in order

          version() showed 9.5

4/- Kill sage 9.5

5/- Restarting notebooks for 9.4, 9.5,9.6B01 in order

          version() showed 9.6 beta1

          9.6 console became active

Please advise if something was done incorrectly in the steps above or something was missing.

Thank you for your help.

Regards,

phiho
