[yt-users] " cannot import name YTDomainOverflow" after hg update to an earlier version

Did you remember to recompile yt? Doing

$ python setup.py develop

in the root of the repository should do the trick.

I'm not sure which revision 13651 corresponds to (revision numbers are not
shared between mercurial repositories, only commit hashes are), but if you
ended up on yt 3.0 and wanted to switch back to 2.x, you can do:

$ hg update yt-2.x
$ python setup.py develop

to go back to the most up-to-date version of the 2.x branch.
