Okay, that's interesting. I am without Internet for a bit, but I have just run on 3.0 with all of the ramses data I have on my laptop without any trouble.

My script is similar to yours, except with "c" instead of [. 5,.5,.5]. I am running on a minor modification of 6fb278bef80f. Which changeset hash are you on?

I'm somewhat worried this will be tricky to debug. Any chance you can also check which fields are in the data file? One sticking point with ramses that I do not yet have a solution for is that the fields must be specified, not guessed, and this is not cleanly implemented yet.

Hi Matt,
Sure, by making the plot "by hand" do you mean something other than:
slc = SlicePlot(pf, 'x', "Density", center=[0.5,0.5,0.5])
slc.save('ramses')

? In that case, I get the same error (sorry -- the "useful" knowledge of yt I've accumulated is still very limited).

Hi Sam,

Could you have a try at making the plot and specifying the center by hand?

Hi yt-users,

I'm compiling from the tip of yt-3.0 where plot seems to be broken for Ramses...
