Marshalling big objects

Discussion in 'Python' started by =?iso-8859-1?Q?=22Orlando_D=F6hring=22?=, Jul 15, 2007.

  1. Dear community,

    I want to marshal objects:

    - http://docs.python.org/lib/module-marshal.html

    where I have problems with a bigger objects, e.g.
    self.contiguousSurfaceResidues, see below.

    I was writing the object to file:

    fDump1 = open('dump_13PK_C.dat','wb')
    marshal.dump(self.contiguousSurfaceResidues, fDump1)
    fDump1.close()

    loading it again:

    fDump1 = open('dump_13PK_C.dat','rb')
    self.contiguousSurfaceResidues = marshal.load(fDump1)
    fDump1.close()

    which yields nonsense as output, i.e. square-symbols etc. How to handle large objects? Thanks.


    Yours,

    Orlando
