[yt-dev] TipsyDataset Will Not Load, and Requires Parameter File

Hi everyone,

I was trying to use yt 3.0 with the Gasoline sample dataset that we have
available on http://yt-project.org/data , and it fails in two ways:

1) yt cannot figure out what the dataset is using the simple "load" command
as in:

from yt.mods import *
ds = load(filename)
...
yt.utilities.exceptions.YTOutputNotIdentified: Supplied
('agora_1e11.0040',) {}, but could not load!



2) When I manually ask it to see the file as a TipsyDataset, it also fails,
as it expects parameters to be set:

from yt.mods import *
ds = TipsyDataset(filename)
...
  File
"/Users/chummels/src/yt-i386/src/yt-hg/yt/frontends/sph/data_structures.py",
line 396, in __init__
    self.parameters['nbodies'],
AttributeError: 'TipsyDataset' object has no attribute 'parameters'


This seems like a bug.  Any ideas as to a solution?  This dataset did not
come with a parameter file for it.
