What does it mean when cPickle.load says:
RuntimeError: invalid signature
Is binary format not portable?
Are you sure that's the actual error message?
I cannot find such message anywhere in the sources.
The pickle format is quite portable, even cross-version. As a generic
answer, make sure you open the file in binary mode, both when writing
and
reading.
Yes, that's the message.
Part of what is pickled is a numpy array. I am writing on a 32-bit
linux system
and reading on a 64-bit system. Reading on the 64-bit system is no
problem.
Maybe the message comes from numpy's unpickling?
Maybe, at least 'invalid signature' makes sense in Numpy. In that case, a
better place to ask would be a numpy specific list, see
