[yt-users] volume rendering

[Nathan Goldbaum]

Hi Renyue,

Which version of yt are you running?  If you installed using the install
script, the output of 'yt instinfo' run on the command line should be
suffieicebt to figure out exactly which version you are using.

You may have to directly import AMRKDTree from
yt.visualization.volume_rendering.api, although I believe it is still
imported into yt.mods in the current stable release of yt.
