[yt-users] parallel config issue

[Sam Skillman]

Hi All,

With the new configuration setup, I'm having issues with parallel analysis:

simple_proj.py:

from yt.mods import *
pf = load('DD1701')
pc = PlotCollection(pf,center=[0.5]*3)
pc.add_projection('Density',0,weight_field='Density')

Below is the full error message.  I'm not sure if this is due to my
implementation somehow or something to do with the config change.  Any help
would be appreciated.

Sam
