Hi, I’m using yt 3.2.2 through miniconda on a Mac. I’m just trying to make a simple phase plot (http://paste.yt-project.org/show/6076/), but I’m getting an error that I don’t understand and can’t seem to fix (http://paste.yt-project.org/show/6077/). I haven’t made a phase plot in a while, but the error started earlier today when I was trying to make a more complex phase plot. So I thought it must have been something I had done, but even going back to this simple phase plot, I’m still seeing the error "AttributeError: 'tuple' object has no attribute ‘_determine_fields’". Any help would be deeply appreciated.
