New issue 417: Lost parameter files, out-of-scope references
https://bitbucket.org/yt_analysis/yt/issue/417/lost-parameter-files-out-of-scope

Anonymous:

This (albiet bad) reference situation invalidates the object created.  An easy way to re-assign the lost references would be handy.

import weakref
pf = load('/scratch/david_c/Paper4/d60_b02_4lev_j32/TD0000/time0000')
h = weakref.proxy(pf.h)
data=h.sphere([0.5]*3,0.05)
pf = load('/scratch/david_c/Paper4/d60_b02_4lev_j32/TD0001/time0001')
h = weakref.proxy(pf.h)
data['Density']

gives
