Re: [Numpy-discussion] 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

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?
