[yt-users] how to call HaloMassFcn

[Matthew Turk]

Hi Geoffrey,

As I mentioned earlier, the version installed on Triton is from before
the reorganization.  Use the yt documentation to get the imports
correctly, and debug the imports on a single core -- you can run the
imports just interactively on the login node.  You don't need the
analysis_modules stuff.  :)

This worked for me:

from yt.mods import *
from yt.extensions.halo_mass_function import *

taken from here:
