New issue 678: SlicePlots don't work for ART in 3.0 https://bitbucket.org/yt_analysis/yt/issue/678/sliceplots-dont-work-for-art-... Nathan Goldbaum: Just tried to make a SlicePlot and ran into what looked like an API incompatibility error. Sorry for not pasting a traceback but unfortunately I found this error while working with someone else so I don't have access to their data.
