[yt-users] yt and ipython notebook

[Mark Krumholz]

Hi All,

I just upgraded to the latest version of yt, including all of yt's favored dependencies, by doing a yt update --all. I found that I can no longer run an ipython notebook. The following command used to work fine before my upgrade:

(yt-x86_64)pfe20:hmc3_mhd_lowden mkrumhol$ ipython notebook --no-browser --port=51707

but now it gives me the following error:

Traceback (most recent call last):

Any suggestions?
