Revision history [back]

As a new sage user, I recently compiled Sage-4.7 from source and it runs smoothly in the command line. However, when I set up the sage notebook, the expression returns no result in browser For instance, if you enter 1+1, then click "Evaluate", the cell turns green but then no result is returned.

I originally thought it was a script-display problem, but then I was able to view output from sagenb.org just fine. Then looking at the terminal, I realized every time I press the "evaluate" at the browser, some error is returned:

2011-06-20 12:55:23-0400 [HTTPChannel,0,10.83.104.47] User 'admin' logged in.

I tried checking the installation using make check and it is fine. Can someone give me some ideas on how to proceed?

Thanks so much!

As a new sage user, I recently compiled Sage-4.7 from source and it runs smoothly in the command line. However, when I set up the sage notebook, the expression returns no result in browser For instance, if you enter 1+1, then click "Evaluate", the cell turns green but then no result it keeps running and never returns anything. The terminal displays the following:

sage: notebook(interface='', server_pool=['sage1@localhost'],
....: ulimit='-v 500000', secure=True, directory="/tmp/work", accounts=True)
The notebook files are stored in: work.sagenb

There is returned.

I originally thought it was a script-display problem, but then I was able to view output from sagenb.org just fine. Then looking at the terminal, I realized every time I press the "evaluate" at the browser, some error is returned:
