[yt-users] YT dies after second attempt to run script

[Francia F. Riesco]

Dear Everybody,
  my name is Francia and I am new working with YT. I have Enzo data  
and I was able to run a basic example of YT. I succeeded to get result  
in my first attempt. However, the same command now gives me and error  
and I am unable to find the solution. I am wondering if somebody has  
gotten this same error.

Mac OS X V 10.7.4
Python 2.7.2 (default, Jul 30 2012, 17:08:59)
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)] on darwin

This is the script I am running:
-----
import sys
from yt.mods import * # set up our namespace

from pkg_resources import load_entry_point
import yt.frontends.enzo.api
yt.frontends.enzo.api.EnzoHierarchy._bn = "%s.grid.cpu%%04i"

from yt.analysis_modules.halo_finding.api  import *


fn = "/Users/friesco/astro/redshift0058/redshift0058"

pf = load(fn) # load data

halos = HaloFinder(pf)

halos.write_out("/Users/friesco/astro/halo_output.out")
---

I got this results

However, when I try to run this same script now I get this

Does anybody have a suggestion?


PS: very nice to meet you! ^_^
