You're probably right in general, for me the 3.3 and 2.7 pickles definitely don't work the same:
3.3: >>> type(pickle.dumps(1)) <type 'bytes'> 2.7: >>> type(pickle.dumps(1, pickle.HIGHEST_PROTOCOL)) <type 'str'> As you can see, in 2.7 when I try to dump something, I get useless string. Look what I gen when I dump an NLTK object such as the sent_tokenize function: '\x80\x02cnltk.tokenize\nsent_tokenize\ng\x00' Now, this is useless. If I try to load it on a platform without NLTK installed on it, I get: ImportError: No module named 'nltk' So it means the actual sent_tokenizer wasn't saved. Just it's module. -- http://mail.python.org/mailman/listinfo/python-list
