[yt-users] Weighed projections

I'm trying to make a density weighted temperature projection on Kraken, and the weighting seems to be causing problems. I get this error: Traceback (most recent call last): File "./s_p_halos.py", line 23, in <module> p = ph.add_projection("Temperature", 0, weight='Density') I'm puzzled because this exact same script works on my laptop, albeit with a much smaller data set. Any ideas or suggestions would be greatly appreciated. Thanks, Brian
