[yt-users] YT from 2.1 to 2.2

[Jun-Hwan Choi]

Hi YT user,

I recently move the stable 2.1 to development 2.2.
Then I try to run simple slice script that worked with 2.1, but it crash
My simple script is as follow:

-------------------------------------
from yt.mods import *
from yt.analysis_modules.api import EnzoSimulation
import matplotlib.pylab as pylab

pf = load("DD0000/DD0000")

# create density slices
pc = PlotCollection(pf, center=[0.5,0.5,0.5])

pc.add_slice("Density", 0)
pc.save("DD0000")
--------------------------------------
and the error message is

Traceback (most recent call last):
  File "SliceDenItr.py", line 1, in <module>
    from yt.mods import *
  File 
"/home/jhchoi/common/lib/python2.6/site-packages/yt-2.2dev-py2.6-linux-x86_64.egg/yt/mods.py", 
line 43, in <module>
    from yt.utilities.cookbook import Intent
  File 
"/home/jhchoi/common/lib/python2.6/site-packages/yt-2.2dev-py2.6-linux-x86_64.egg/yt/utilities/cookbook.py", 
line 30, in <module>
    import argparse
ImportError: No module named argparse

Does anyone know the reason of error and way to fix it?

Thanks in advance,
Junhwan Choi
