Hi folks,
I am having a problem making weighted projections in yt-3. Using the
current tip, when I type this:
plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'),
weight_field=None, width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save()
everything works fine, and I get a projection. However, when I try this:
plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'),
weight_field=('gas', 'density'), width=(1.0,'unitary'),
center=[0.5,0.5,0.5]).save()
I get the error:

465 if weight is not None:

467 if 'Cutting' in self.data_source.__class__.__name__:
468 type = 'OffAxisSlice'
AttributeError: 'tuple' object has no attribute 'replace'
I would note that if I use 'density' instead of ('gas','density') for the
weight_field, everything works fine. Is this the expected behavior, or is
this a bug?
Thanks!
