Hi Francis, That's a good idea. We should have a firedrake-update --environment to also upgrade all the python packages in the virtualenv. Cheers, David On Wed, 1 Mar 2017 at 10:58 Francis Poulin <fpoulin@uwaterloo.ca> wrote:

Hello Lawrence,

Yes, that did the trick. Sorry for the bother.

I realize that normally, we might not want to update everything, including ipython, but is there an option if we wanted to update everything? Might be helpful for people like me who don't know exactly what to update, like ipykernel.

Not to see if I can do the exercises in the notebook.

Cheers, Francis

Thanks for the suggestion. I thought that firedrake-update would update ipython, but I guess not. I will try and remember do that from time to time.

Yes, although it runs the upgrade cycle for direct firedrake components, we don't upgrade every package installed inside the virtualenv (since this would take too long, and we don't directly control all of that).

As you can see below, I have now joined the modern times and have version 5.3.0, but it still seems to have problem with updating the kernel. I did try it again with jupyter and it still failed.

Actually, when I try ipython notebook it fails as well.

Should I remove ipython and try reinstalling it?

Oh, sorry, I think the error was not directly ipython. Please also try:

$ pip install -U jupyter $ pip install -U ipykernel

and then go round again...

Thanks,
