I wonder if anyone can shed some light on a troublesome intermittent problem I am having. Firstly the necessary: I am running on windows XP, using jython 2.1 and java 1.3.1_03. A pickled file is created as follows: pickle.dump((self.seq.getMotifs(), self.s[self.seqIdx]), newFile) self.seq.getMotifs() simply returns a dictionary containing various complex python objects (which will have been created and used sucessfully) self.s[self.seqIdx] is a python sequence object. Intermittently, when I try and reload from this pickle file I get the following exception: Exception occurred during event dispatching: Traceback (innermost last): File "pars.py", line 129, in OpenFile File "D:\program files\jython-2.1\Lib\pickle.py", line 947, in load File "D:\program files\jython-2.1\Lib\pickle.py", line 567, in load File "D:\program files\jython-2.1\Lib\pickle.py", line 885, in load_setitem TypeError: unhashable type I have read that this error typically can occur when a pyDictionary or pyList is inserted into a hashtable. Is this a problem that anyone else is familiar with, is it a limitation of the jython implementation of pickle? Any help will be appreciated Blobby |
