[yt-users] Unpickling phase plots

[david collins]

Hi there--

I have a phase plot that I pickled on one machine, and moved to my
laptop and want to re-plot.  I pickled it like this:
fptr=open(filename,'rb')
cPickle.dump(pc.plots[-1].data,fptr,protocol=-1)

I want to unpickle it like this:
obj = cPickle.load( open(filename) )

but I get this parameter file error (full traceback below):

return self._convert_pf(self._records[hash])
KeyError: (('32aa7d1d4941760ffd8fdcab4ea97e1f',), <function
_reconstruct_pf at 0x101f9d050>,
('32aa7d1d4941760ffd8fdcab4ea97e1f',))

I suspect that the key error is because I don't have the original
dataset on this machine (due to disk space) so the pf store on this
machine doesn't have that key.  Does that sound right, and is there a
work around for that?

This is a technique I've used in the past, so in principle it's sound.

Thanks,
d.
