Yes -- pickling isn't meant to work across different python versions (it might
to some extent, but I wouldn't try it unless there is no way around it). Using
netcdf as a data format instead of pickling might also be a solution (if
intermediate storage on the disk is not too inefficient, but your original
approach involved that anyway). Konrad Hinsen has written a nice wrapper for
python that is quite easy to use:
