Re: [yt-users] pc.save with old Enzo
Sorry -- correction: this problem also occurs with a new data set from Enzo 2.0. It doesn't happen, however, with the older version of yt. The version it fails on is 9cb628620da6 (yt). Unfortunately, the version it works on gives an error linked with finding the mercurial libraries when I run yt instinfo, so I'm not sure which version it is.

To get it to work with .grid.cpu*, put this at the top of your script:
import yt.frontends.enzo.api
yt.frontends.enzo.api.EnzoHierarchy._bn = "%s.grid.cpu%%04i"
The error thrown by quiver looks like an out-of-date matplotlib
installation. Sam, Jeff and JC have been improving the quiver plots,
one aspect of which is adding the ability to scale the arrows to a
given length. That uses the scale_units parameter to quiver, which is
definitely part of matplotlib 1.0.0 (the version that ships with the
current yt, and has done so for quite a while). They may be able to
provide more insight, but upgrading matplotlib or re-running the
install script should fix it.
