Hi Varadarajan,
does yt's load method any sort of error? Could you try the following script:

from yt.mods import *
pf = load("/.../.../testproblem/data.nnnn.dbl.h5")
slc = SlicePlot(pf, 'z', 'rho')
slc.save()

this should create an slice plot of gas density, but the most
interesting part is load(). It should take care of reading and
interpreting all data from hdf5 file.
Best regards,
Kacper
