Converting a pickle to python3

[Paulo da Silva]

Hi!

I have a big data structure cpickled into a datafile, by python2.
I tried to unpickle it using python3 but got the followin message:
File "/usr/lib64/python3.1/pickle.py", line 1372, in loads
encoding=encoding, errors=errors).load()
_pickle.UnpicklingError: invalid load key, 'x'.

Is there a way to "stream" a class in python2 and then get it back in
python3?

Thanks for any help/comments.

Please ignore this question. The problem is not the pickle thing but a
compress function I have that has problems related with the new
str/bytes stuff.

Sorry.
