Hi all,
Thanks to the quick help, I could upgrade my sage to 4.7.1 (from
4.7.0). However, I am unable to run the notebook. And I also get a
similar error when I run sage by itself. Do I need to recompile some
packages? Thanks for any help.
I will present below two logs. The first one is when sage is run. And
the second one is when sage-notebook is run.
