Hi,

I just updated yt and now I'm getting, e.g., the following when I run
PlotCollection:
Traceback (most recent call last):
  File "rhot_plot.py", line 6, in <module>
    pc = PlotCollection(pf)

error message)

Ideas?  As a short-term solution, is there a way I can revert to an
earlier version?

Thanks!
