[yt-users] Error on installation of yt on system python

[trobolo dinni]

Dear yt users,

I usually install yt on system python, following the procedure suggested me
in this mailing list some months ago. In general everything goes fine with
the installation and I can normally use yt.

Now I installed Ubuntu from scratch in my computer (where previously yt was
installed and running!) and the installation seems to fine, but when I
insert the command "from yt.mods import * ", I get the following error:

I would like to ask if someone has an idea of how can I solve this problem.

Thanks,
