[yt-users] Help with volume rendering

[Luc Menard]

Hi, I am extremely new to using yt and I have encountered an error while
attempting some simple volume rendering. I was using the yt-cookbook script
to attempt to make some images, and everything was working fine until I get
to the "cam.snapshot()" command. It gives me this error.


>>> cam.snapshot("hello.png", double_check = True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/mnt/home/menardlu/yt-x86_64/src/yt-hg/yt/visualization/volume_rendering/camera.py",
line 764, in snapshot
    self.initialize_source()
  File
"/mnt/home/menardlu/yt-x86_64/src/yt-hg/yt/visualization/volume_rendering/camera.py",
line 716, in initialize_source
    self.no_ghost)
  File
"/mnt/home/menardlu/yt-x86_64/src/yt-hg/yt/utilities/amr_kdtree/amr_kdtree.py",
line 178, in initialize_source
    self.set_fields(fields, log_fields, no_ghost)
  File
"/mnt/home/menardlu/yt-x86_64/src/yt-hg/yt/utilities/amr_kdtree/amr_kdtree.py",
line 165, in set_fields
    del self.bricks, self.brick_dimensions
AttributeError: bricks


Any help would be greatly appreciated.

     Thank you,
             Luc Menard
