[yt-users] need to set omega_baryon in yt-3

Hmm.  So when I tried that, using:

ad =
ds.region(center=[0.5,0.5,0.5],left_edge=[0,0,0],right_edge=[1,1,1],field_parameters
= {'omega_baryon':0.046})

(as ds.all_data() does not accept any additional arguments), I get this
error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

----> 1 ad =
ds.region(center=[0.5,0.5,0.5],left_edge=[0,0,0],right_edge=[1,1,1],field_parameters
= {'omega_baryon':0.046})

/Users/bwoshea/Desktop/yt-3.0/src/yt-hg/yt/data_objects/selection_data_containers.pyc
in __init__(self, center, left_edge, right_edge, fields, ds, **kwargs)
    577     def __init__(self, center, left_edge, right_edge, fields = None,
    578                  ds = None, **kwargs):
--> 579         YTSelectionContainer3D.__init__(self, center, fields, ds,
**kwargs)
    580         if not isinstance(left_edge, YTArray):
    581             self.left_edge = self.ds.arr(left_edge, 'code_length')

TypeError: __init__() got multiple values for keyword argument
'field_parameters'

Is that expected behavior, or do I misunderstand what you're saying?

Thanks,
Brian
