[yt-users] Iteration Problems

[Stephen Skory]

Hi all,

so it looks like Brian Crosby's problem is that in order to run a multiple-cycle halo finding script, the halos object needs to be explicitly deleted. This is probably my fault with all the various levels of referencing done in halo finding, but for the time being, a script like this will *not* run away in memory. I've confirmed this on both Ranger & Triton for yt-1.7.

from yt.mods import *

for n in range(0,28):
    pf = load("RD%04i/RedshiftOutput%04i" % (n,n))
    halos = HaloFinder(pf,padding=0.1)
    halos.write_out("RD%04i/MergerHalos%04i.txt" % (n,n))
    halos.write_particle_lists("RD%04i/MergerHalos%04i" % (n,n))
    halos.write_particle_lists_txt("RD%04i/MergerHalos%04i" % (n,n))
    del halos

(p.s. Brian Crosby - please note that this is based on your halos.py script on Ranger, but you missed the dir names in the output commands. Without them you're just over-writing your old work!) _______________________________________________________
