cPickle.load says 'invalid signature'
The file is pickle saved on i386 and loaded on x86_64. It contains a numpy array (amoungst other things). On load it says: RuntimeError: invalid signature Is binary format not portable?

There's no such message in Numpy source code, so the error does not come directly from Numpy. Did you try to isolate the problem a bit more by producing the pickle file without the array?
It's a wild guess, but try to save your pickle with 'wb' as argument of open, and protocol=-1. Then open it with 'rb'. It helped me fix some cross-platform issues in the past. -=- Olivier 2011/5/18 Neal Becker <ndbecker2@gmail.com>
