The problem is that I NEED that array sizes to be 1 or 2 bytes and I dont know how to get around this problem without arrays. Any help would be greatly appreciated. TIA AM Aseem Mohanty wrote:
why does a call to array.array() cause an unpickleable error??
the pickle docs on the python site dont mention anything about arrays, nor do the array docs mention about pickling.
i have a feeling that it might be because of the fact that arrays are dynamic data structures and thus the pickler doesnt really know about its limits (of course I could be totally and miserably wrong) i couldnt find anything in the docs to support my 'feeling' and the source is kind of above my current level of expertise in python
any help would be appreciated or i am doomed to a major rewrite....
the source in my product that causes the error :
self.K=array.array('H') self.L=array.array('B') self.R=array.array('H')
TIA AM
